anxietyMale mice exposed to chronic social stress have anxious female offspring    ScienceDaily (Aug. 22, 2012) — A study in mice conducted by researchers at Tufts University School of Medicine suggests that a woman’s risk of anxiety and dysfunctional social behavior may depend on the experiences of her parents, particularly fathers, when they were young.   The study, published online in Biological Psychiatry, suggests that stress caused by chronic social instability during youth contributes to epigenetic changes in sperm cells that can lead to psychiatric disorders in female offspring across multiple generations.   Link

The anxious idiot   The New York Times (Aug. 11, 2012) by Daniel Smith – One day last year, I called my brother Scott in a state of agitation, self-hatred and incipient despair. Scott was at work and short on time. I got straight to the point. “I’m in a state of agitation, self-hatred and incipient despair!” I cried.  “Tell me more,” Scott said. “What is it?”  “I’m anxious — again! I’m anxious day and night. I wake up anxious and I go to bed anxious. I’m a total wreck. And I’m not doing anything to help myself! I know what helps and I’m not doing it! What’s wrong with me? Why am I not doing the things I know full well will make me feel better?”   “Oh,” Scott said. “That’s an easy one. It’s because you’re an idiot.” Then he said he’d call me after work    Link

Anxious girls’ brains work harder   ScienceDaily (June 5, 2012) — In a discovery that could help in the identification and treatment of anxiety disorders, Michigan State University scientists say the brains of anxious girls work much harder than those of boys.  The finding stems from an experiment in which college students performed a relatively simple task while their brain activity was measured by an electrode cap. Only girls who identified themselves as particularly anxious or big worriers recorded high brain activity when they made mistakes during the task.   Link

Obese people can suffer from social anxiety disorder due to weight alone  ScienceDaily (July 1, 2011) — A new study from Rhode Island Hospital researchers shows that obese individuals with social anxiety related only to their weight may experience anxiety as severe as individuals with social anxiety disorder (SAD). The findings directly conflict with the criteria for SAD in the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV). The study is now published online in advance of print in the journal Depression and AnxietyLink

Does eating give you pleasure, or make you anxious?  ScienceDaily (May 21, 2011) — While most people have a great deal of difficulty in dieting and losing weight, particularly if a diet extends over many months or years, individuals with anorexia nervosa can literally diet themselves to death. In fact, this disorder has a very high death rate from starvation. A new study sheds light on why these symptoms occur in anorexia nervosa.  Link

When parents try to control every little bite:  Being too restrictive about your child’s diet can backfire, experts say  msnbc.com: Health (Sep. 3, 2009) by Bridget Murray Law — Driven by concern about childhood obesity or other food anxieties, more nutrition-focused parents are turning into food cops, monitoring every morsel their children eat…In fact, a recent study found that being too restrictive about the foods children eat can cause more weight gain. Researchers from the Center for Childhood Obesity Research at Pennsylvania State University, University Park, found the highest weight gain among girls who considered their parents most restrictive about eating certain foods. The study tracked 200 girls for 10 years from age 5.  Link

Finding fear: Neuroscientists locate where it is stored in the brain  ScienceDaily (July 8, 2009) — Fear is a powerful emotion, and neuroscientists have for the first time located the neurons responsible for fear conditioning in the mammalian brain. Fear conditioning is a form of Pavlovian, or associative, learning and is considered to be a model system for understanding human phobias, post-traumatic stress disorder and other anxiety disorders.   Link

Brain chemical reduces anxiety, increases survival of new cells  ScienceDaily (May 13, 2009) — New research on a brain chemical involved in development sheds light on why some individuals may be predisposed to anxiety. It also strengthens understanding of cellular processes that may be common to anxiety and depression, and suggests how lifestyle changes may help overcome both.  Link

Genetics of fear: Specific genetic variations contribute to anxiety disorders, study suggests  ScienceDaily (Mar. 11, 2009) — Polymorphisms are variations in genes which can result in changes in the way a particular gene functions and thus may be associated with susceptibility to common diseases. In a new study in Psychological Science, psychologist Tina B. Lonsdorf and her colleagues from the Karolinska Institutet in Sweden and the University of Greifswald in Germany examined the effect of specific polymorphisms on how fear is learned and how that fear is subsequently overcome.   Link
