Anxiety linked to higher long-term risk of stroke

American Heart Association Rapid Access Journal Report The greater your anxiety level, the higher your risk of having a stroke, according to new research published in the American Heart Association journal Stroke. The study is the first in which researchers linked anxiety and stroke independent of other factors such as depression. Anxiety disorders are one of the most prevalent mental health problems. Symptoms include feeling unusually worried, stressed, nervous or tense. Over a 22 year period, researchers studied a nationally representative group of 6,019 people 25-74 years old in the first National Health and Nutrition Examination Survey (NHANES I). Participants underwent an interview and took blood tests, medical examinations and completed psychological questionnaires to gauge anxiety and depression levels. Researchers tracked strokes through hospital or nursing home reports and death certificates. After accounting for other factors, they found that even modest increases in anxiety were associated with greater stroke risk. People in the highest third of anxiety symptoms had a 33 percent higher stroke risk than those with the lowest levels. "Everyone has some anxiety now and then. But when it's elevated and/or chronic, it may have an effect on your vasculature years down the road," said Maya Lambiase, Ph.D., study author and cardiovascular behavioral medicine researcher in the Department of Psychiatry at the University of Pittsburgh School of Medicine, in Pittsburgh, Penn. People with high anxiety levels are more likely to smoke and be physically inactive, possibly explaining part of the anxiety-stroke link. Higher stress hormone levels, heart rate or blood pressure could also be factors, Lambiase said. In earlier work, researchers found that depression was linked to greater risk of stroke. In contrast to anxiety, depression is a persistent feeling of hopelessness, dejection, and lack of energy, among other symptoms.

Heavy marijuana users have abnormal brain structure and poor memory

Drug abuse appears to foster brain changes that resemble schizophrenia CHICAGO --- Teens who were heavy marijuana users -- smoking it daily for about three years -- had abnormal changes in their brain structures related to working memory and performed poorly on memory tasks, reports a new Northwestern Medicine® study. A poor working memory predicts poor academic performance and everyday functioning. The brain abnormalities and memory problems were observed during the individuals' early twenties, two years after they stopped smoking marijuana, which could indicate the long-term effects of chronic use. Memory-related structures in their brains appeared to shrink and collapse inward, possibly reflecting a decrease in neurons. The study also shows the marijuana-related brain abnormalities are correlated with a poor working memory performance and look similar to schizophrenia-related brain abnormalities. Over the past decade, Northwestern scientists, along with scientists at other institutions, have shown that changes in brain structure may lead to changes in the way the brain functions. This is the first study to target key brain regions in the deep subcortical gray matter of chronic marijuana users with structural MRI and to correlate abnormalities in these regions with an impaired working memory. Working memory is the ability to remember and process information in the moment and -- if needed -- transfer it to long-term memory. Previous studies have evaluated the effects of marijuana on the cortex, and few have directly compared chronic marijuana use in otherwise healthy individuals and individuals with schizophrenia. The younger the individuals were when they started chronically using marijuana, the more abnormally their brain regions were shaped, the study reports. The findings suggest that these regions related to memory may be more susceptible to the effects of the drug if abuse starts at an earlier age. "The study links the chronic use of marijuana to these concerning brain abnormalities that appear to last for at least a few years after people stop using it," said lead study author Matthew Smith, an assistant research professor in psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine. "With the movement to decriminalize marijuana, we need more research to understand its effect on the brain." Alcoholism and Drug Abuse Counselors Continuing Education The paper will be published Dec. 16 in the journal Schizophrenia Bulletin. In the U.S., marijuana is the most commonly used illicit drug and young adults have the highest -- and growing -- prevalence of use. Decriminalization of the drug may lead to greater use. Because the study results examined one point in time, a longitudinal study is needed to definitively show if marijuana is responsible for the brain changes and memory impairment. It is possible that the abnormal brain structures reveal a pre-existing vulnerability to marijuana abuse. But evidence that the younger a subject started using the drug the greater his brain abnormality indicates marijuana may be the cause, Smith said. The groups in the study started using marijuana daily between 16 to 17 years of age for about three years. At the time of the study, they had been marijuana free for about two years. A total of 97 subjects participated, including matched groups of healthy controls, subjects with a marijuana use disorder, schizophrenia subjects with no history of substance use disorders, and schizophrenia subjects with a marijuana use disorder. The subjects who used marijuana did not abuse any other drugs. Few studies have examined marijuana's effect on the deep regions in the brain -- the 'subcortical gray matter' below the noodle-shaped cortex. The study also is unique in that it looked at the shapes of the striatum, globus pallidus and thalamus, structures in the subcortex that are critical for motivation and working memory. The Marijuana and Schizophrenia Connection Chronic use of marijuana may contribute to changes in brain structure that are associated with having schizophrenia, the Northwestern research shows. Of the 15 marijuana smokers who had schizophrenia in the study, 90 percent started heavily using the drug before they developed the mental disorder. Marijuana abuse has been linked to developing schizophrenia in prior research. "The abuse of popular street drugs, such as marijuana, may have dangerous implications for young people who are developing or have developed mental disorders," said co-senior study author John Csernansky, M.D., chair of psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine and Northwestern Memorial Hospital. "This paper is among the first to reveal that the use of marijuana may contribute to the changes in brain structure that have been associated with having schizophrenia." Chronic marijuana use could augment the underlying disease process associated with schizophrenia, Smith noted. "If someone has a family history of schizophrenia, they are increasing their risk of developing schizophrenia if they abuse marijuana," he said. While chronic marijuana smokers and chronic marijuana smokers with schizophrenia both had brain changes related to the drug, subjects with the mental disorder had greater deterioration in the thalamus. That structure is the communication hub of the brain and is critical for learning, memory and communications between brain regions. The brain regions examined in this study also affect motivation, which is already notably impaired in people with schizophrenia. "A tremendous amount of addiction research has focused on brain regions traditionally connected with reward/aversion function, and thus motivation," noted co-senior study author Hans Breiter, M.D., professor of psychiatry and behavioral sciences and director of the Warren Wright Adolescent Center at Feinberg and Northwestern Memorial. "This study very nicely extends the set of regions of concern to include those involved with working memory and higher level cognitive functions necessary for how well you organize your life and can work in society." "If you have schizophrenia and you frequently smoke marijuana, you may be at an increased risk for poor working memory, which predicts your everyday functioning," Smith said. ### The research was supported by grants R01 MH056584 and P50 MH071616 from the National Institute of Mental Health and grants P20 DA026002 and RO1 DA027804 from National Institute of Drug Abuse, all of the National Institutes of Health.

Gene found to be crucial for formation of certain brain circuitry

Identified using new technique that can speed identification of genes, drug candidates Using a powerful gene-hunting technique for the first time in mammalian brain cells, researchers at Johns Hopkins report they have identified a gene involved in building the circuitry that relays signals through the brain. The gene is a likely player in the aging process in the brain, the researchers say. Additionally, in demonstrating the usefulness of the new method, the discovery paves the way for faster progress toward identifying genes involved in complex mental illnesses such as autism and schizophrenia — as well as potential drugs for such conditions. A summary of the study appears in the Dec. 12 issue of Cell Reports. "We have been looking for a way to sift through large numbers of genes at the same time to see whether they affect processes we're interested in," says Richard Huganir, Ph.D., director of the Johns Hopkins University Solomon H. Snyder Department of Neuroscience and a Howard Hughes Medical Institute investigator, who led the study. "By adapting an automated process to neurons, we were able to go through 800 genes to find one needed for forming synapses — connections — among those cells." Although automated gene-sifting techniques have been used in other areas of biology, Huganir notes, many neuroscience studies instead build on existing knowledge to form a hypothesis about an individual gene's role in the brain. Traditionally, researchers then disable or "knock out" the gene in lab-grown cells or animals to test their hypothesis, a time-consuming and laborious process. In this study, Huganir's group worked to test many genes all at once using plastic plates with dozens of small wells. A robot was used to add precise allotments of cells and nutrients to each well, along with molecules designed to knock out one of the cells' genes — a different one for each well. "The big challenge was getting the neurons, which are very sensitive, to function under these automated conditions," says Kamal Sharma, Ph.D., a research associate in Huganir's group. The team used a trial-and-error approach, adjusting how often the nutrient solution was changed and adding a washing step, and eventually coaxed the cells to thrive in the wells. In addition, Sharma says, they fine-tuned an automated microscope used to take pictures of the circuitry that had formed in the wells and calculated the numbers of synapses formed among the cells. The team screened 800 genes in this way and found big differences in the well of cells with a gene called LRP6 knocked out. LRP6 had previously been identified as a player in a biochemical chain of events known as the Wnt pathway, which controls a range of processes in the brain. Interestingly, Sharma says, the team found that LRP6 was only found on a specific kind of synapse known as an excitatory synapse, suggesting that it enables the Wnt pathway to tailor its effects to just one synapse type. "Changes in excitatory synapses are associated with aging, and changes in the Wnt pathway in later life may accelerate aging in general. However, we do not know what changes take place in the synaptic landscape of the aging brain. Our findings raise intriguing questions: Is the Wnt pathway changing that landscape, and if so, how?" says Sharma. "We're interested in learning more about what other proteins LRP6 interacts with, as well as how it acts in different types of brain cells at different developmental stages of circuit development and refinement." Another likely outcome of the study is wider use of the gene-sifting technique, he says, to explore the genetics of complex mental illnesses. The automated method could also be used to easily test the effects on brain cells of a range of molecules and see which might be drug candidates Continuing Education for Social Workers ### Other authors on the paper are Se-Young Choi, now of Seoul National University School of Dentistry; Yong Zhang, Shunyou Long and Min Li of Johns Hopkins University School of Medicine; and Thomas J.F.

Aging and gene expression -- possible links to autism and schizophrenia in offspring

Advanced paternal age has been associated with greater risk for psychiatric disorders, such as schizophrenia and autism. With an increase in paternal age, there is a greater frequency of certain types of mutations that contribute to these disorders in offspring. Mutations are changes in the genetic code. Recent research, however, looks beyond the genetic code to "epigenetic effects", which do not involve changes in the genes themselves, but rather in how they are expressed to determine one's characteristics. Such epigenetic changes in sperm, related to ageing, have been linked with psychiatric disorders in offspring. Maria Milekic, PhD, reported today, at the American College of Neuropsychopharmacology annual meeting in Hollywood Florida, that old mice have an epigenetic change ‒ a loss of DNA methylation at the locations where the genetic code starts being transcribed. DNA methylation is a biochemical process that plays an important regulatory role in development and disease. The work was done by a research team in the Department of Psychiatry at Columbia University. Offspring of old fathers showed the same deficit in DNA methylation, and they differed in their behavior from the offspring of the young fathers. They showed less exploratory activity and differed in the startle response and in habituation. Two groups, with 10 breeder mice per group, were tested. The breeders were either old (12 month) or young (3 month) males, each bred with two young (3 month) female mice. Then the behavior of the offspring was tested when they were 3 months old. DNA methylation also was tested in the young and old fathers' sperm, and brains of the offspring were tested for DNA methylation as well as gene expression. "We were interested in understanding the mechanism of the paternal age effect", said Dr. Milekic."The risk for schizophrenia increases 2-fold when a father is over 45 years of age, and the risk for autism increases 2-5-fold. It seemed unlikely that mutation alone could account for this. We therefore speculated that DNA methylation could provide an alternative mechanism." Not only did the offspring of the old fathers differ from their counterparts with young fathers in DNA methylation, they also showed significant differences in the expression of genes that have been implicated in autism spectrum disorders and that are known to regulate the development and function of the brain. These findings point to possible factors that can lead to autism spectrum disorders and schizophrenia, and ultimately may lead to more effective therapeutic interventions. With respect to studies in the immediate future, Dr. Milekic said,"We are trying to evaluate changes in different brain regions. Our studies before did not compare brain regions. Most of the genes that have altered expression are in the cerebellum. We are interested in how DNA methylation in the cerebellum is affected by paternal age."

Mental stress + heart disease: Stronger presence in women under 50

Patients with recent heart attack tested with public speaking task Researchers have found that women younger than 50 with a recent heart attack are more likely to experience restricted blood flow to the heart (myocardial ischemia) in response to psychological stress. The finding may partly explain why younger women who are hospitalized after a heart attack face a greater risk of complications and dying, compared to men of the same age. The results are scheduled to be presented Wednesday, Nov. 20 at the American Heart Association Scientific Sessions meeting in Dallas. Researchers at Emory University have been studying the responses of patients who recently had a heart attack to exercise stress and mental stress, in the form of public speaking on an emotional topic. They have found that women age 50 and below are more likely to experience mental stress-induced ischemia, compared to men of the same age (52 percent compared to 25 percent). The MIMS (Myocardial Infarction and Mental Stress) study included 49 men and 49 women, age-matched pairs who all had a heart attack in the last six months. Their ages ranged from 38 to 59. Among study participants older than 50, there were no significant sex differences in mental stress-induced ischemia;, however, men older than 50 had a rate of exercise-induced ischemia that was twice as high as women of a similar age. "This is the first study to examine the cardiovascular effects of psychological stress as a possible mechanism for the greater mortality after myocardial infarction among younger women," says study leader Viola Vaccarino, MD, PhD, professor and chair of the Department of Epidemiology, Rollins School of Public Health. "We saw a dramatic difference in mental stress-induced ischemia specifically in younger women. In addition, when ischemia was graded in a continuous way, we saw that it was twice as severe among the younger women." Women who experience a heart attack before age 50 are relatively rare, suggesting that perhaps those who do simply have more severe heart disease. However, even when investigators adjusted for different rates of traditional heart disease risk factors such as smoking and diabetes, the disparity remained. In fact, women tended to have less severe coronary artery disease, measured by examining the degree of blockage in their coronary arteries. One possible explanation the Emory investigators considered was a higher burden of psychosocial stress, Vaccarino says. In the study, the younger women were more often poor, of minority race, with a history of sexual abuse and with higher levels of depressive symptoms. "Yet if we look at the statistics, factors such as poverty, race and depression do not explain the difference," she says. "Yes, women have more stressors. But our data show that women also may be more vulnerable to the effects of mental stress on the heart." "This could be an added stimulus to the medical community to pay more attention to the emotional factors in cardiac patients. We are now taking a closer look at potential physiological factors that account for the additional susceptibility in younger women." Emory researchers working with Vaccarino have identified two areas where there are specific differences in younger women who had a recent heart attack: inflammation and heart rate variability, a measure of the responsiveness of the autonomic nervous system. Low heart rate variability has been previously linked to greater heart disease risk. The inflammation data is being presented in a poster by postdoctoral researcher Cherie Rooks, PhD on Sunday, Nov. 17 and the heart rate variability data in a poster by assistant professor Amit Shah, MD on Tuesday, Nov. 19. Interleukin-6 is a marker of inflammation that goes up and down quickly depending on someone's environmental exposures including mental stress, even in healthy individuals. In the MIMS study, women age 50 and below had much higher levels of IL-6 in their blood, compared to age-matched men, both before the mental stress test and afterwards. Women and men older than 50 had similar levels of IL-6. Heart rate goes up in response to physical or psychological stress, but the beats also become more evenly spaced. Heart rate variability is a measure of how much moment-to-moment fluctuation is present; higher heart rate variability is a marker of a more flexible, and thus healthier, autonomic system. In the MIMS study, younger women had their heart rate variability dip more in response to stress, compared to men the same age. This is additional evidence that young women after a heart attack may be more vulnerable to the adverse effects of psychological stress on the heart. Vaccarino and her colleagues are continuing to investigate mental stress-induced ischemia, including how it affects mortality and complication rates, in a second phase of the MIMS study at Emory, which will include a larger sample with patient follow-up Alcoholism and Drug Abuse Counselors Continuing Education ### How the study was conducted The mental stress test part of the study was a public speaking task involving an emotional topic. Participants were asked to imagine a real-life stressful situation, such as a close relative been mistreated in a nursing home. They had to quickly prepare a speech and deliver it in front of a video camera and an audience wearing white coats, while their blood pressure and other vital signs were monitored. Immediately afterwards, cardiac imaging was performed to assess blood flow within the heart via SPECT (single photon emission computed tomography). On a separate day, study participants performed a standard exercise test on a treadmill; a few were unable to exercise at a high heart rate and had to have a "pharmacological" stress test with a drug that dilates coronary arteries.

Brain connectivity study reveals striking differences between men and women

Penn Medicine brain imaging study helps explain different cognitive strengths in men and women PHILADELPHIA—A new brain connectivity study from Penn Medicine published today in the Proceedings of National Academy of Sciences found striking differences in the neural wiring of men and women that's lending credence to some commonly-held beliefs about their behavior. In one of the largest studies looking at the "connectomes" of the sexes, Ragini Verma, PhD, an associate professor in the department of Radiology at the Perelman School of Medicine at the University of Pennsylvania, and colleagues found greater neural connectivity from front to back and within one hemisphere in males, suggesting their brains are structured to facilitate connectivity between perception and coordinated action. In contrast, in females, the wiring goes between the left and right hemispheres, suggesting that they facilitate communication between the analytical and intuition. "These maps show us a stark difference--and complementarity--in the architecture of the human brain that helps provide a potential neural basis as to why men excel at certain tasks, and women at others," said Verma. For instance, on average, men are more likely better at learning and performing a single task at hand, like cycling or navigating directions, whereas women have superior memory and social cognition skills, making them more equipped for multitasking and creating solutions that work for a group. They have a mentalistic approach, so to speak. Past studies have shown sex differences in the brain, but the neural wiring connecting regions across the whole brain that have been tied to such cognitive skills has never been fully shown in a large population. In the study, Verma and colleagues, including co-authors Ruben C. Gur, PhD, a professor of psychology in the department of Psychiatry, and Raquel E. Gur, MD, PhD, professor of Psychiatry, Neurology and Radiology, investigated the gender-specific differences in brain connectivity during the course of development in 949 individuals (521 females and 428 males) aged 8 to 22 years using diffusion tensor imaging (DTI). DTI is water-based imaging technique that can trace and highlight the fiber pathways connecting the different regions of the brain, laying the foundation for a structural connectome or network of the whole brain. This sample of youths was studied as part of the Philadelphia Neurodevelopmental Cohort, a National Institute of Mental Health-funded collaboration between the University of Pennsylvania Brain Behavior Laboratory and the Center for Applied Genomics at the Children's Hospital of Philadelphia. The brain is a roadmap of neural pathways linking many networks that help us process information and react accordingly, with behavior controlled by several of these sub-networks working in conjunction. In the study, the researchers found that females displayed greater connectivity in the supratentorial region, which contains the cerebrum, the largest part of the brain, between the left and right hemispheres. Males, on the other hand, displayed greater connectivity within each hemisphere. By contrast, the opposite prevailed in the cerebellum, the part of the brain that plays a major role in motor control, where males displayed greater inter-hemispheric connectivity and females displayed greater intra-hemispheric connectivity. These connections likely give men an efficient system for coordinated action, where the cerebellum, which involves perception, and the front of the brain, which involves action, are bridged together, according to the authors. The female connections likely facilitate integration of the analytic and sequential processing modes of the left hemisphere with the spatial, intuitive information processing modes of the right side. The authors observed only a few gender differences in the connectivity in children younger than 13 years, but the differences were more pronounced in adolescents aged 14 to 17 years and young adults older than 17. The findings were also consistent with a Penn behavior study, of which this imaging study was a subset of, that demonstrated pronounced sexual differences. Females outperformed males on attention, word and face memory, and social cognition tests. Males performed better on spatial processing and sensorimotor speed. Those differences were most pronounced in the 12 to 14 age range. "It's quite striking how complementary the brains of women and men really are," said Dr. Ruben Gur. "Detailed connectome maps of the brain will not only help us better understand the differences between how men and women think, but it will also give us more insight into the roots of neuropsychiatric disorders, which are often sex related." Next steps are to quantify how an individual's neural connections are different from the population; identify which neural connections are gender specific and common in both; and to see if findings from functional magnetic resonance imaging (fMRI) studies fall in line with the connectome data Professional Counselor Continuing Education ### Co-authors of the study include Madhura Ingalhalikar, Alex Smith, Drew Parker, Theodore D.

PTSD raises risk for obesity in women

Women with PTSD gain weight more rapidly than women without disorder Women with post-traumatic stress disorder (PTSD) gain weight more rapidly and are more likely to be overweight or obese than women without the disorder, find researchers at Columbia University's Mailman School of Public Health and Harvard School of Public Health. It is the first study to look at the relationship between PTSD and obesity over time. Results appear online in JAMA Psychiatry. One in nine women will have PTSD at sometime over the course of their lifetime—twice as often as men. Women are also more likely to experience extreme traumatic events like rape that carry a high risk for the disorder. "PTSD is not just a mental health issue," says study senior author Karestan Koenen, PhD, Mailman School associate professor of Epidemiology. "Along with cardiovascular disease and diabetes, we can now add obesity to the list of known health risks of PTSD." PTSD - Clinical Practice Guideline for Management of Post Traumatic Stress CEU Course "The good news from the study is that it appears that when PTSD symptoms abate, risk of becoming overweight or obese is also significantly reduced," says first author Laura D. Kubzansky, PhD, Professor of Social and Behavioral Sciences at Harvard School of Public Health. However, despite the growing evidence of potential far-reaching problems associated with PTSD, it's estimated that only half of women in the United States with the disorder are ever treated. "Hopefully, wider recognition that PTSD can also influence physical health will improve this statistic, leading to better screening and treatments, including those to prevent obesity," says Dr. Kubzansky. While it's known that women with PTSD have high rates of obesity, it has been unclear whether PTSD was actually driving the weight gain. To explore the issue, the researchers analyzed data collected from 50,504 women, aged 22-44 years, taking part in the Nurses' Health Study II between 1989 and 2009. Participants were asked about the worst trauma they experienced and if they had related post-traumatic stress symptoms. The threshold for PTSD was the persistence of four or more symptoms over a month or longer. Common symptoms include re-experiencing the traumatic event, feeling under threat, social avoidance, and numbness. Normal-weight women who developed PTSD during the study period had 36% increased odds of becoming overweight or obese compared with women who experienced trauma but had no symptoms of PTSD. The higher risk was evident even for women with sub-threshold symptoms levels and remained after adjusting for depression, which has also been proposed as a major risk factor for obesity. In women with PTSD that began prior to the study period, body mass index increased at a more rapid pace than women without PTSD. The observed effect of PTSD on obesity is likely stronger in the general population of women than in nurses, notes Dr. Koenen. "Nurses are great for studies because they report health measures like BMI with a high degree of accuracy. But they are also more health conscious and probably less likely to become obese than most of us, which makes these results more conservative than they would otherwise be." Symptoms of PTSD rather than the trauma itself seemed to be behind the weight gain. "We looked at the women who developed PTSD and compared them to women who experienced trauma but did not develop PTSD. On the whole, before their symptoms emerged, the rate of change in BMI was the same as the women who never experienced trauma or did experience trauma but never developed symptoms," says Dr. Kubzansky. How exactly does PTSD lead to weight gain? The biological pathway is unknown, but scientists have a number of guesses. One is through the over-activation of stress hormones. PTSD may lead to disturbances in functioning of the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, each of which are involved in regulating a broad range of body processes, including metabolism. Another is through unhealthy behavior patterns that may be used to cope with stress. Ongoing research is looking at whether PTSD increases women's preference for processed foods and decreases their likelihood of exercising Social Worker Continuing Education ### Co-authors include Pula Bordelois, MPH, and Andrea Roberts, PhD, at Harvard School of Public Health; Hee Jin Jun, DrPH, at the Channing Division of Network Medicine at Brigham and Women's Hospital; Noah Blustone, BA, at Harvard Medical School and Boston University; and Magdalena Cerda, DrPH, at Columbia's Mailman School.

Focusing on faces

Researchers find neurons in amygdala of autistic individuals have reduced sensitivity to eye region of others' faces Difficulties in social interaction are considered to be one of the behavioral hallmarks of autism spectrum disorders (ASDs). Previous studies have shown these difficulties to be related to differences in how the brains of autistic individuals process sensory information about faces. Now, a group of researchers led by California Institute of Technology (Caltech) neuroscientist Ralph Adolphs has made the first recordings of the firings of single neurons in the brains of autistic individuals, and has found specific neurons in a region called the amygdala that show reduced processing of the eye region of faces. Furthermore, the study found that these same neurons responded more to mouths than did the neurons seen in the control-group individuals. "We found that single brain cells in the amygdala of people with autism respond differently to faces in a way that explains many prior behavioral observations," says Adolphs, Bren Professor of Psychology and Neuroscience and professor of biology at Caltech and coauthor of a study in the November 20 issue of Neuron that outlines the team's findings. "We believe this shows that abnormal functioning in the amygdala is a reason that people with autism process faces abnormally." The amygdala has long been known to be important for the processing of emotional reactions. To make recordings from this part of the brain, Adolphs and lead author Ueli Rutishauser, assistant professor in the departments of neurosurgery and neurology at Cedars-Sinai Medical Center and visiting associate in biology at Caltech, teamed up with Adam Mamelak, professor of neurosurgery and director of functional neurosurgery at Cedars-Sinai, and neurosurgeon Ian Ross at Huntington Memorial Hospital in Pasadena, California, to recruit patients with epilepsy who had electrodes implanted in their medial temporal lobes—the area of the brain where the amygdala is located—to help identify the origin of their seizures. Epileptic seizures are caused by a burst of abnormal electric activity in the brain, which the electrodes are designed to detect. It turns out that epilepsy and ASD sometimes go together, and so the researchers were able to identify two of the epilepsy patients who also had a diagnosis of ASD. By using the implanted electrodes to record the firings of individual neurons, the researchers were able to observe activity as participants looked at images of different facial regions, and then correlate the neuronal responses with the pictures. In the control group of epilepsy patients without autism, the neurons responded most strongly to the eye region of the face, whereas in the two ASD patients, the neurons responded most strongly to the mouth region. Moreover, the effect was present in only a specific subset of the neurons. In contrast, a different set of neurons showed the same response in both groups when whole faces were shown. "It was surprising to find such clear abnormalities at the level of single cells," explains Rutishauser. "We, like many others, had thought that the neurological abnormalities that contribute to autism were spread throughout the brain, and that it would be difficult to find highly specific correlates. Not only did we find highly specific abnormalities in single-cell responses, but only a certain subset of cells responded that way, while another set showed typical responses to faces. This specificity of these cell populations was surprising and is, in a way, very good news, because it suggests the existence of specific mechanisms for autism that we can potentially trace back to their genetic and environmental causes, and that one could imagine manipulating for targeted treatment." "We can now ask how these cells change their responses with treatments, how they correspond to similar cell populations in animal models of autism, and what genes this particular population of cells expresses," adds Adolphs. To validate their results, the researchers hope to identify and test additional subjects, which is a challenge because it is very hard to find people with autism who also have epilepsy and who have been implanted with electrodes in the amygdala for single-cell recordings, says Adolphs. "At the same time, we should think about how to change the responses of these neurons, and see if those modifications correlate with behavioral changes," he says MHC Continuing Education ### Funding for the research outlined in the Neuron paper, titled "Single-neuron correlates of abnormal face processing in autism," was provided by the Simons Foundation, the Gordon and Betty Moore Foundation, the Cedars-Sinai Medical Center, Autism Speaks, and the National Institute of Mental Health.

Most teen mental health problems go untreated

Less than half of teenagers with mental health problems receive any sort of treatment DURHAM, N.C. -- More than half of adolescents with psychiatric disorders receive no treatment of any sort, says a new study by E. Jane Costello, a Duke University professor of psychology and epidemiology and associate director of the Duke Center for Child and Family Policy. When treatment does occur, the providers are rarely mental health specialists, says the study, which was based on a survey of more than 10,000 American teenagers LPC Continuing Education The country's mental health system has come under scrutiny in recent years, following a string of mass shootings, such as the murders at Columbine High in Colorado, in which mental illness seems to have played a role. The new study underlines the need for better mental health services for adolescents, Costello said. "It's still the case in this country that people don't take psychiatric conditions as seriously as they should," Costello said. "This, despite the fact that these conditions are linked to a whole host of other problems." Costello noted that not all teens in the study fared the same. Treatment rates varied greatly for different mental disorders, for instance. Adolescents with ADHD, conduct disorder or oppositional defiant disorder received mental health care more than 70 percent of the time. By contrast, teens suffering from phobias or anxiety disorders were the least likely to be treated. Results also varied greatly by race, with black youths significantly less likely to be treated for mental disorders than white youths. The care that teenagers received also varied greatly. In many cases, care was provided by pediatricians, school counselors or probation officers rather than by people with specialized mental health training. There simply are not enough qualified child mental health professionals to go around, Costello said. "We need to train more child psychiatrists in this country," Costello said. "And those individuals need to be used strategically, as consultants to the school counselors and others who do the lion's share of the work." The study draws on data from the National Comorbidity Survey Adolescent Supplement, a nationally representative face-to-face survey of 10,148 adolescents between the ages of 13 and 17. It was published online Nov. 15 in Psychiatric Services Youth with Co-occuring Substance Abuse and Mental Health Disorders CE Course ### The research was supported by NIDA (grants U01-DA024413, DA011301, and DA022308), NIMH (grant MH083964), and the NIMH Intramural Research Program.

Bradley Hospital researchers link lack of sleep in teens to higher risk of illness

Study also finds consistent sleep pattern can reduce risk of illness EAST PROVIDENCE, R.I. – Newly released findings from Bradley Hospital published in the Journal of Sleep Research have found that acute illnesses, such as colds, flu, and gastroenteritis were more common among healthy adolescents who got less sleep at night. Additionally, the regularity of teens' sleep schedules was found to impact their health. The study, titled "Sleep patterns are associated with common illness in adolescents," was led by Kathryn Orzech, Ph.D. of the Bradley Hospital Sleep Research Laboratory CEUs For Nurses Orzech and her team compared three outcomes between longer and shorter sleepers: number of illness bouts, illness duration, and school absences related to illness. The team found that bouts of illness declined with longer sleep for both male and female high school students. Longer sleep was also generally protective against school absences that students attributed to illness. There were gender differences as well, with males reporting fewer illness bouts than females, even with similar sleep durations. Orzech's team analyzed total sleep time in teens for six-day windows both before and after a reported illness and found a trend in the data toward shorter sleep before illness vs. wellness. Due to the difficulty of finding teens whose illnesses were spaced in such a way to be statistically analyzed, Orzech also conducted qualitative analysis, examining individual interview data for two short-sleeping males who reported very different illness profiles. This analysis suggested that more irregular sleep timing across weeknights and weekends (very little sleep during the week and "catching up" on sleep during the weekend), and a preference for scheduling work and social time later in the evening hours can both contribute to differences in illness outcomes, conclusions that are also supported in the broader adolescent sleep literature. "Some news reaches the general public about the long-term consequences of sleep deprivation, such as the links between less sleep and weight gain," said Orzech. "However, most of the studies of sleep and health have been done under laboratory conditions that cannot replicate the complexities of life in the real world. Our study looked at rigorously collected sleep and illness data among adolescents who were living their normal lives and going to school across a school term." "We showed that there are short-term outcomes, like more acute illness among shorter-sleeping adolescents, that don't require waiting months, years or decades to show up," Orzech continued. "Yes, poor sleep is linked to increased cardiovascular disease, to high cholesterol, to obesity, to depression, etc., but for a teenager, staying healthy for the dance next week, or the game on Thursday, may be more important. This message from this study is clear: Sleep more, and more regularly, get sick less." Mary Carskadon, Ph.D., director of the Bradley Hospital Sleep Research Laboratory, commented on Orzech's study, "We have long been examining the sleep cycles of teenagers and how we might be able to help adolescents - especially high school students - be better rested and more functional in a period of their lives where sleep seems to be a luxury." Carskadon continued, "In the future, these findings identifying specific issues in individual sleep patterns may be a useful way to help adolescents begin to prioritize sleep." ### Research reported in this publication was supported by the National Institute of Mental Health of the National Institutes of Health under award numbers MH45945 and MH79179, and T32 training grant MH19927.

Regenstrief and IU study: Older adults with severe mental illness challenge healthcare system

INDIANAPOLIS – Although older adults with serious mental illness didn't have more recorded physical illness and had fewer outpatient visits to primary care physicians, they made more medical emergency department visits and had considerably longer medical hospitalizations than older adults without mental illness according to a study conducted by researchers from the Regenstrief Institute and the Indiana University Center for Aging Research. "Our comparison of health care utilization between seriously mentally ill patients and age-matched primary-care patients provides critical data for the physicians, health care systems and policy makers who will be caring for the growing number of older adults, many of whom have mental illness," said Regenstrief Institute investigator Hugh C. Hendrie, M.B., Ch.B., D.Sc., Indiana University Center for Aging Research center scientist and professor of psychiatry at the IU School of Medicine. Dr. Hendrie, who is a geriatric psychiatrist and health services researcher, is the first author of the study. The study, "Comorbidity Profile and Healthcare Utilization in Elderly Patients With Serious Mental Illnesses," is published in the December issue of The American Journal of Geriatric Psychiatry. A 2012 report from the Institute of Medicine estimated that as many of one in five older adults have one or more mental health conditions or problems stemming from substance misuse or abuse. The IOM report authors included Regenstrief Institute investigator Christopher Callahan, M.D., Cornelius and Yvonne Pettinga Professor of Medicine at the IU School of Medicine who is also a co-author of the new study. Dr. Callahan is founding director of the IU Center for Aging Research Social Worker Continuing Education The American Journal of Geriatric Psychiatry study notes, "The increased likelihood of falls together with the significantly greater number of emergency department visits and length of hospitalization also suggest that those with severe mental illness represent a vulnerable elderly population that deserve more intensive studies, leading hopefully to a better integrated model of medical and psychiatric care including consideration of psychosocial factors." Individuals with severe mental illness in the study were patients of Eskenazi Health Midtown Community Mental Health. The patients had severe chronic depression (48 percent), schizophrenia (39 percent) and bipolar disorder (14 percent). Others in the study were patients from Wishard-Eskenazi primary care sites. "This study highlights a major challenge faced by older adults with severe mental illnesses and the increased burden it places on our health care system," said Julie L. Szempruch, RN, CNS, associate vice president of Eskenazi Health Midtown Community Mental Health. ### Authors of "Comorbidity Profile and Healthcare Utilization in Elderly Patients With Serious Mental Illnesses," in addition to Drs.

Clinician observations of preschoolers' behavior help to predict ADHD at school age

Consider how preschool children behave across multiple contexts to identify those at risk for later ADHD, study emphasizes Don't rely on one source of information about your preschoolers' inattention or hyperactivity. Rather, consider how your child behaves at home as well as information from his or her teacher and a clinician. This advice comes from Sarah O'Neill, of The City College of New York, based on research she conducted at Queens College (CUNY), in an article published in Springer's Journal of Abnormal Child Psychology. The study examines how well parent, teacher, and clinician ratings of preschoolers' behavior are able to predict severity and diagnosis of attention deficit hyperactivity disorder (ADHD) at age six Professional Counselor Continuing Education Characterized by developmentally inappropriate levels of inattention, hyperactivity, and impulsivity, ADHD is one of the most frequently diagnosed childhood psychiatric disorders. Although many studies focusing on school-aged children have shown that parents and teachers -- rather than clinician observations alone -- are more likely to assess ADHD accurately, scant evidence exists to support similar conclusions with preschoolers. To fill this gap in the research, O'Neill and colleagues followed a group of 104 hyperactive and/or inattentive three- and four-year-olds for a period of two years. Both parents and teachers rated the preschoolers' behavior. In addition, clinicians, who were blind to parent and teacher reports, completed ratings of preschoolers' behavior during a psychological testing session. By the time the children reached age six, more than half (53.8 percent) had been diagnosed with ADHD. The likelihood of such a diagnosis increased when all three informants had rated the child as high on symptoms at age three or four. Furthermore, after analyzing the reports separately, the research team found that parents' reports were critical, particularly when combined with either teacher or clinician reports. Teacher reports alone were not as useful, and the research team ascribed the relative inability of educators' reports to predict a child's ADHD status over time to possible situational variables. Preschoolers may initially have difficulty adjusting to the structured classroom setting, but this disruptive behavior is time-limited to the transition to school. Teachers' perceptions of "difficult" behavior may also be affected by factors such as classroom setting and size as well as their expectations of children's behavior. As a result of the study findings, O'Neill and her team emphasize the importance of using information from multiple informants who have seen the child in different settings. Parent reports of preschoolers' behavior appear to be crucial, but these alone are not sufficient. Augmenting the parent report with that of the teacher and/or clinician is necessary. Also important are clinician observations of preschoolers during psychological testing, which are predictive of an ADHD diagnosis and its severity over time. Being able to identify children at risk for poorer outcomes may help educators and clinicians to plan appropriate interventions. "Consider a preschool child's behavior in different contexts," O'Neill emphasized. "Although parents' reports of preschoolers' inattention, hyperactivity, or impulsivity are very important, ideally we would not rely solely on them. At least for young children, the clinician's behavioral observations appear to hold prognostic utility." ### Reference: O'Neill, S. et al. (2013).

Johns Hopkins research may improve early detection of dementia

Using scores obtained from cognitive tests, Johns Hopkins researchers think they have developed a model that could help determine whether memory loss in older adults is benign or a stop on the way to Alzheimer's disease. The risk of developing dementia increases markedly when a person is diagnosed with mild cognitive impairment, a noticeable and measurable decline in intellectual abilities that does not seriously interfere with daily life. But physicians have no reliable way to predict which people with mild cognitive impairment are likely to be in the 5 to 10 percent a year who progress to dementia. In a proof-of-concept study, the Johns Hopkins investigators analyzed records of 528 people age 60 and over, who were referred to the Johns Hopkins Medical Psychology Clinic for cognitive testing as part of a dementia work-up between 1996 and 2004. The results were compared to those of 135 healthy older adults who participated in a study of normal aging. Both groups completed tests of memory, language, attention, processing speed and drawing abilities from which 13 scores were recorded Nursing CEUs Since each person is naturally more skillful in some areas than in others, the scores of healthy adults showed a symmetrical, bell-shaped range: Most of their scores were high, a few were a bit lower, and a few were even lower. By grouping the patients into cohorts based on the severity of their dementia, the researchers found a trend in the test scores that is likely to mimic the deterioration of an individual's scores over time. At the outset, he says, Alzheimer's disease subtly disrupts some mental abilities, while leaving others intact. Thus, well before a person develops clear cognitive impairment, his or her performance declines slightly on a few measures. When shown on a graph, these changes cause the healthy symmetric, bell-shaped curve to shift and become asymmetrical. Regardless of how low a person's test scores were, the researchers determined that lopsidedness in their score distribution correlated with dementia. They predicted that people with low scores that were evenly distributed were not likely to develop dementia. But those with clearly lopsided test score distributions on the 13 measures administered were already experiencing varying levels of dementia. "Departures from the normal bell-shaped pattern of variability on cognitive tests might determine which people with low scores develop dementia," says David J. Schretlen, Ph.D., a professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine and leader of a study published online Nov. 12 in the journal Neuropsychology. Since these declines can be subtle, the researchers also increased the precision of cognitive testing by accounting for the effects of age, sex, race and education on test performance. The challenge for doctors, Schretlen explains, is that most normal, healthy people will produce a few low scores on cognitive testing. That makes it nearly impossible to know at the outset whether a patient who reports forgetfulness and produces one or two low scores has a benign form of mild cognitive impairment, or is in the earliest stage of dementia. As a result, doctors often tell such patients to return for follow-up testing in a year or two. But if future research confirms it, this new statistical model could help doctors get the prognosis right earlier in the disease, at the first visit, and start treating patients accordingly. Mostly, Schretlen says, doctors could use the new model to reassure patients who are not at risk of dementia, while fast-tracking interventions for those who are. Because there currently are no effective treatments for Alzheimer's disease, those likely headed that way could be counseled to take the good time they have to organize their affairs, and do things they have always wanted to do. They also could be fast-tracked into clinical trials of medications to slow the progression of dementia. "If we are going to have any hope of helping patients with Alzheimer's disease, we need to do it as early as possible," Schretlen says. "Once the brain deteriorates, there's no coming back." Recent failures of drugs in late-stage clinical trials for Alzheimer's disease have been a real blow, he adds, but new treatments are being developed. The new way of reading existing test scores follows a 2008 study by the same researchers showing that one of every six healthy adults scored poorly on two or more of 10 tests in a brief cognitive battery — even though there was nothing wrong with them. The main reason it is difficult to tell whether older people have benign mild cognitive impairment or not is because they are not routinely screened for cognitive impairment, he says. A visit to a specialist comes only after someone has noticed symptoms, and then cognitive testing is interpreted without the benefit of a baseline assessment. What would solve this problem, he says, would be for everyone over the age of 55 to get routine neurocognitive testing every five years. ### The study was supported by the Therapeutic Cognitive Neuroscience Fund; the Benjamin and Adith Miller Family Endowment on Aging, Alzheimer's and Autism; the William and Mary Ann Wockenfuss Research Fund Endowment; and the National Institutes of Health's National Institute of Mental Health (MH60504).

New study identifies signs of autism in the first months of life

Scientists at Marcus Autism Center, Children's Healthcare of Atlanta and Emory University School of Medicine identify markers of social disability present in 2 to 6-month-old infants later diagnosed with autism Researchers at Marcus Autism Center, Children's Healthcare of Atlanta and Emory University School of Medicine have identified signs of autism present in the first months of life. The researchers followed babies from birth until 3 years of age, using eye-tracking technology, to measure the way infants look at and respond to social cues. Infants later diagnosed with autism showed declining attention to the eyes of other people, from the age of 2 months onwards. The results are reported in the Nov. 6, 2013 advanced online publication of the journal Nature. The study followed two groups of infants, one at low and one at high risk for having autism spectrum disorders. High-risk infants had an older sibling already diagnosed with autism, increasing the infant's risk of also having the condition by 20 fold. In contrast, low-risk infants had no first, second, or third degree relatives with autism. "By following these babies from birth, and intensively within the first six months, we were able to collect large amounts of data long before overt symptoms are typically seen," said Warren Jones, Ph.D., the lead author on the study. Teams of clinicians assessed the children longitudinally and confirmed their diagnostic outcomes at age 3. Then the researchers analyzed data from the infants' first months to identify what factors separated those who received an autism diagnosis from those who did not. What they found was surprising MFT Intern Continuing Education "We found a steady decline in attention to other people's eyes, from 2 until 24 months, in infants later diagnosed with autism," said co-investigator Ami Klin, Ph.D., director of Marcus Autism Center. Differences were apparent even within the first 6 months, which has profound implications. "First, these results reveal that there are measurable and identifiable differences present already before 6 months. And second, we observed declining eye fixation over time, rather than an outright absence. Both these factors have the potential to dramatically shift the possibilities for future strategies of early intervention." Jones is director of research at Marcus Autism Center and assistant professor in the Department of Pediatrics at Emory University School of Medicine. Klin is director of Marcus Autism Center, chief of the Division of Autism & Related Disorders in the Department of Pediatrics at Emory University School of Medicine and a Georgia Research Alliance Eminent Scholar. The researchers caution that what they observed would not be visible to the naked eye, but requires specialized technology and repeated measurements of a child's development over the course of months. "To be sure, parents should not expect that this is something they could see without the aid of technology," said Jones, "and they shouldn't be concerned if an infant doesn't happen to look at their eyes at every moment. We used very specialized technology to measure developmental differences, accruing over time, in the way that infants watched very specific scenes of social interaction." Before they can crawl or walk, babies explore the world intensively by looking at it, and they look at faces, bodies, and objects, as well as other people's eyes. This exploration is a natural and necessary part of infant development, and it sets the stage for brain growth. The critical implications of the study relate to what it reveals about the early development of social disability. Although the results indicate that attention to others' eyes is already declining by 2 to 6 months in infants later diagnosed with autism, attention to others' eyes does not appear to be entirely absent. If infants were identified at this early age, interventions could more successfully build on the levels of eye contact that are present. Eye contact plays a key role in social interaction and development, and in the study, those infants whose levels of eye contact diminished most rapidly were also those who were most disabled later in life. This early developmental difference also gives researchers a key insight for future studies. "The genetics of autism have proven to be quite complex. Many hundreds of genes are likely to be involved, with each one playing a role in just a small fraction of cases, and contributing to risk in different ways in different individuals," said Jones. "The current results reveal one way in which that genetic diversity may be converted into disability very early in life. Our next step will be to expand these studies with more children, and to combine our eye-tracking measures with measures of gene expression and brain growth." ### The study, Attention to Eyes is Present But In Decline in 2-6 Month-Olds Later Diagnosed with Autism was funded by the Simons Foundation, the National Institute of Mental Health, the Marcus Foundation and the Whitehead Foundation.

OHSU Vollum Institute research gives new insight into how antidepressants work in the brain

Vollum Institute scientist publishes two papers on neurotransmission in today’s edition of Nature Research from Oregon Health & Science University's Vollum Institute, published in the current issue of Nature, is giving scientists a never-before-seen view of how nerve cells communicate with each other. That new view can give scientists a better understanding of how antidepressants work in the human brain — and could lead to the development of better antidepressants with few or no side effects. The article in today’s edition of Nature came from the lab of Eric Gouaux, Ph.D., a senior scientist at OHSU's Vollum Institute and a Howard Hughes Medical Institute Investigator. The article describes research that gives a better view of the structural biology of a protein that controls communication between nerve cells. The view is obtained through special structural and biochemical methods Gouaux uses to investigate these neural proteins. The Nature article focuses on the structure of the dopamine transporter, which helps regulate dopamine levels in the brain. Dopamine is an essential neurotransmitter for the human body's central nervous system; abnormal levels of dopamine are present in a range of neurological disorders, including Parkinson's disease, drug addiction, depression and schizophrenia. Along with dopamine, the neurotransmitters noradrenaline and serotonin are transported by related transporters, which can be studied with greater accuracy based on the dopamine transporter structure. The Gouaux lab's more detailed view of the dopamine transporter structure better reveals how antidepressants act on the transporters and thus do their work Alcoholism and Drug Abuse Counselors Continuing Education The more detailed view could help scientists and pharmaceutical companies develop drugs that do a much better job of targeting what they're trying to target — and not create side effects caused by a broader blast at the brain proteins. "By learning as much as possible about the structure of the transporter and its complexes with antidepressants, we have laid the foundation for the design of new molecules with better therapeutic profiles and, hopefully, with fewer deleterious side effects," said Gouaux. Gouaux's latest dopamine transporter research is also important because it was done using the molecule from fruit flies, a dopamine transporter that is much more similar to those in humans than the bacteria models that previous studies had used. The dopamine transporter article was one of two articles Gouaux had published in today’s edition of Nature. The other article also dealt with a modified amino acid transporter that mimics the mammalian neurotransmitter transporter proteins targeted by antidepressants. It gives new insights into the pharmacology of four different classes of widely used antidepressants that act on certain transporter proteins, including transporters for dopamine, serotonin and noradrenaline. The second paper in part was validated by findings of the first paper — in how an antidepressant bound itself to a specific transporter. "What we ended up finding with this research was complementary and mutually reinforcing with the other work — so that was really important," Gouaux said. "And it told us a great deal about how these transporters work and how they interact with the antidepressant molecules." Gouaux's discoveries over the years in neurotransmission have established him as one of the top investigators in his field. His research has important implications for understanding the mechanisms of not just antidepressants, but also drugs used for the treatment of a wide range of psychiatric and neurological diseases. Gouaux's co-authors on the dopamine transporter paper were both members of his lab; Aravind Penmatsa, Ph.D., and Kevin Wang, Ph.D. Gouaux's co-authors on the second Nature paper were also members or former members of his lab: Hui Wang, Ph.D.; April Goehring, Ph.D.; Kevin Wang, Aravind Penmatsa and Ryan Ressler, Ph.D. Both papers were funded by the American Heart Association, the National Institute of Mental Health, (1F32MH093120 and 5R37MH070039) and the Howard Hughes Medical Institute.

Depression Therapy Effective for Poor, Minority Moms

Faced with the dual demands of motherhood and poverty, as many as one fourth of low-income minority mothers struggle with major depression. But the stigma associated with mental illness coupled with limited access to quality treatment prevent the majority of these struggling women from receiving help. Now a new study shows that screening for the disorder and providing short-term, relationship-focused therapy through weekly home visits can relieve depression among minority mothers, even in the face of poverty and personal histories of abuse or violence. Such help can have far reaching benefits not only for mothers, but also for their children, say the authors. "It's amazing, really," says psychologist Sheree Toth, lead author and executive director of the University of Rochester's Mt. Hope Family Center. "This research tracked a 14-week intervention for mothers who are terribly overwhelmed, surrounded by high-crime neighborhoods, lacking social support, and often traumatized—my fear was, 'this is never going to work.'" But to the surprise of Toth and her Rochester team, the series of convenient, one-hour therapy sessions relieved depression in participants much better than standard clinic-based care. The study participants also continued to improve eight-months after the treatment ended, regaining a sense of hope and control over their lives and reporting feeling more connected to and supported by others. For example, on the Beck Depression Inventory (BDI), a widely used questionnaire in which a score of 19 or above indicates major depression, women in the study group saw their depressive symptoms decline from an average of 27 at the beginning of therapy to 9.6 eight months after the program concluded. By contrast, women who received community care remained clinically depressed, with an average BDI score of 21 at the follow-up.

Women who received home-based interpersonal therapy saw their depression subside by the end of treatment and continue to improve eight months later. Women who received standard care experienced much less relief. The results, says Toth, point to the need for screening high-risk populations. None of these women were seeking treatment, but were identified instead through a questionnaire and an interview at physicians' offices and clinics for the Women, Infants, and Children (WIC) subsidized nutrition program. Says Toth: "When I go to the doctor, they ask me if I use my seatbelt. Why would we not be asking questions about depression when we know the chances of being hit by a car are way less than the chances of being hit by depression? People are suffering needlessly." Published online November 8 in Development and Psychopathology, the findings are good news for mothers and their children alike. "Extensive research has shown that young children whose primary caregivers are depressed often begin life on the wrong foot," explains Toth. "They may fail to develop secure attachments, setting them up for a cascade of difficulties, from behavior problems during childhood and failure in school to involvement in the juvenile justice system and major psychiatric problems down the road." Despite the widespread prevalence of depression among minority mothers, researchers have largely overlooked this vulnerable population. "In fact, studies that formed the empirical base for the American Psychiatric Association guidelines for depression treatment included 3,860 participants, with only 27 identified as African American and none as being of Latina descent," the authors write. To address the imbalance, the researchers tracked 128 low-income mothers of one-year-olds, 60 percent of whom were Black, 20 percent Hispanic, and 20 percent Caucasian. In addition to poverty, the vast majority of these mothers faced extensive life challenges. All but 6 percent had been depressed for more than a year, 87 percent reported histories of child abuse, 30 percent had been raped or sexually assaulted by a relative, and 27 percent suffered from posttraumatic stress disorder. The study tested the effectiveness of interpersonal psychotherapy, a short-term depression treatment that has worked with more advantaged populations. "A big part of this approach is instilling hope," says Robin Sturm, a co-author and one of the family therapists who worked on the study. She and other therapists first help clients recognize that feelings, such as a lack of energy or motivation, are symptoms of depression not signs of laziness or other character flaws. "If they can separate themselves from the symptoms, it helps them see that they can get better," says Sturm. The bulk of the intervention then focuses on identifying and easing one or two key relationship problems in clients' lives. This could be overcoming the loss of a loved one, reconnecting with a family member, or learning how to resolve conflicts with a partner. Using a variety of tools, from role-playing to analyzing arguments, participants practice more effective ways to interact. "The aha moment is when these women realize, 'I have a sense of control,'" says Sturm. "Perhaps there is domestic violence. They can't control what the other person does, but they can control what they do. That stuck feeling is the hallmark of depression." A critical element of the study model was to offer therapy in clients' homes, an option chosen by 85 percent of participants. "It sends a powerful message that I am willing to come to you," explains Sturm, who, if needed, also met with clients in her car or drove them to the clinic for their appointment. "When people are depressed, it may be too hard to have the energy to make it to appointments," she says. The program's flexibility also reduced the need for childcare and transportation, resulting in a compliance rate of 100 percent, the authors report. Therapists were also sensitive to the stigma of mental illness in minority communities. If clients appeared uncomfortable with a diagnosis like depression, therapists used terms like overwhelmed or moody instead and stressed that such feelings were common for parents faced with the demands of childrearing. Instead of therapy, they sometimes describe their appointments as "spending some time talking about how you are feeling." The program involved no anti-depressants or other medication, further distancing the intervention from psychiatric care, says Sturm. To assess the effectiveness of this flexible, problem-solving approach, the study randomly assigned a second group of mothers to standard community care, matched by race, education, age, and other factors. The control group received clinic-based counseling or cognitive behavior therapy, a common short-term treatment for depression, along with a variety of other interventions, including medication, support groups, and marital and family counseling. The comparison was clear: home-based, interpersonal psychotherapy lifted depression much more effectively than standard care. The findings underscore the importance of actively screening and offering culturally sensitive, convenient care for our most vulnerable populations, says co-author Fred Rogosch, associate professor of psychology at the University of Rochester and director of research for Mt. Hope Family Center. In one clinical trial, 83 percent of low-income young minority women referred for treatment for depression did not attend even one session. "Most of these women don't even like to talk about depression. Most of these women would never have asked for treatment," says Rogosch. "When I go to the doctor, they ask me if I use my seatbelt," says Sheree Toth. "Why would we not be asking questions about depression when we know the chances of being hit by a car are way less than the chances of being hit by depression? People are suffering needlessly." "We also are concerned about the children of mothers who feel isolated, helpless, and angry. That is not the ideal emotional environment for infants and toddlers to grow up in. Reaching out to these mothers is critical for their children," says Rogosch. Even with the creative accommodations offered in this study, Rogosch notes that 40 percent of mothers identified as depressed declined all care. The authors suggest that future research should explore ways to make the interview process even more welcoming.

CWRU study finds mending ruptures in client-therapist relationship during PTSD treatment has positive benefits

In order for prolonged exposure therapy, an evidence-based psychotherapy for PTSD, to reach its full potential, any misperceptions or ruptures in trust and communication between therapist and client need fixing, according to a new Case Western Reserve University study. The study, reported in the Journal of Consulting and Clinical Psychology online article, “Patterns of Therapeutic Alliance: Rupture-Repair Episodes in Prolonged Exposure for PTSD,” is among the first to examine how ruptures in the relationship between the therapist and client can damage a patient’s treatment outcome. An alliance rupture may occur when there is a break in the therapist-client bond. For example, ruptures in the therapeutic relationship may occur when therapeutic progress stalls, negative feelings arise between the therapist and client, or when the work in therapy becomes challenging PTSD - Clinical Practice Guideline for Management of Post Traumatic Stress “We want therapists to know that a rupture in the therapeutic relationship isn’t a bad thing, as long as the therapist tends to it,” said Stephanie Keller, one of the study’s researchers and a Case Western Reserve doctoral student in clinical psychology. “However, if the rupture is not repaired, then your patient may not do as well in treatment.” The research study included 116 people who experienced a traumatic event such as childhood sexual or physical abuse, physical assault, or combat exposure, and had a primary diagnosis of PTSD. Participants engaged in a 10-session treatment program called prolonged exposure (PE) therapy. To help therapists chart progress and examine the therapeutic relationship, each client assessed his or her own PTSD symptoms and perception of their relationship with the therapist during treatment. This helped researchers to identify those clients who experience no ruptures in the therapeutic relationship (a stable relationship), clients who experienced a rupture that was subsequently repaired, and those with ruptures that went unrepaired LCSW Continuing Education The first PE session outlined what would happen over the course of treatment to set specific goals. Exposure-based exercises began in the second session, which included exposure to anxiety-provoking situations that served as trauma-reminders and talking about their traumatic experiences. In this sample, 28 percent of patients experiences a repaired rupture and 18 percent experienced a rupture, or dip in the therapeutic relationship, that was never repaired. An unresolved rupture in the therapist-client relationship became a predictor for a poorer outcome in treatment, Keller said. She also said more research is needed to figure out why these alliance ruptures occur and how to best repair them. The research was funded through a National Institute of Mental Health PTSD research project, directed by Norah Feeny, Ph. D. from Case Western Reserve University and Lori A. Zoellner, Ph. D. from the University of Washington. Other researchers contributing to the project were lead investigator and Case Western Reserve alumna AnnaMaria Aguirre McLauglin, and Eric A. Youngstrom, of the University of North Carolina at Chapel Hill.
