Why do some persons succumb to post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? A new UCLA study may shed light on the answer. http://medicalxpress.com/news/2012-04-post-traumatic-stress-disorder-genes-therapies.html Psychology & Psychiatry Mon, 02 Apr 2012 04:33:09 EST news252559973 Individuals with major depressive disorder (MDD) often undergo multiple courses of antidepressant treatment during their lives. This is because the disorder can recur despite treatment and because finding the right medication for a specific individual can take time. http://medicalxpress.com/news/2012-03-brain-antidepressants.html Psychology & Psychiatry Mon, 26 Mar 2012 16:14:04 EST news251997227 Neuroscience might seem to have little to do with economics, but over the last decade researchers have begun combining these disparate fields, mining the latest advances in brain imaging and genetics to get a better understanding of the biological basis for human behavior. http://medicalxpress.com/news/2012-03-brain-science-economics.html Psychology & Psychiatry Tue, 06 Mar 2012 11:33:08 EST news250255977 Previous studies have found that human behavior during a recession is remarkably different than that during a bullish economy. For example, people tend to spend more time focused on working and less time engaging in leisure and recreation activities, resulting in fewer motor vehicle and other accidents. http://medicalxpress.com/news/2012-02-economic-factors-impact-orthopaedic-trauma.html Other Tue, 07 Feb 2012 16:43:34 EST news247855402 A new study uses a mathematical model to predict the potential impact of expanding treatment to discordant couples on controlling the global HIV epidemic-- in these couples one partner has HIV infection and the other does not. The research conducted at ICAP at Columbia University's Mailman School of Public Health and the Semel Institute of Neuroscience and Human Behavior at University of California in Los Angeles (UCLA) is the first to predict the effect of the expansion of such treatment in couples on the HIV epidemic in certain African countries. http://medicalxpress.com/news/2011-10-hiv-treatment-couples-significantly-global.html HIV & AIDS Tue, 18 Oct 2011 11:28:09 EST news238156082 A new study reveals how the delay computer users sometimes experience when making video calls over the internet can actually help communication in some circumstances, even though it is frustrating in many others. http://medicalxpress.com/news/2011-10-video.html Psychology & Psychiatry Tue, 11 Oct 2011 12:02:11 EST news237553316 Winning may not be the only thing, but the human brain devotes a lot of resources to the outcome of games, a new study by Yale researchers suggest. http://medicalxpress.com/news/2011-10-brain.html Neuroscience Wed, 05 Oct 2011 12:32:40 EST news237036740 The human body has a love-hate relationship with iron.

The Brown University-led research also found that participants believed the therapy to be credible and acceptable. http://medicalxpress.com/news/2011-09-computerized-anxiety-therapy-small-trial.html Psychology & Psychiatry Wed, 14 Sep 2011 13:15:09 EST news235224880 (Medical Xpress) -- Women who are clinically depressed at the time they enter drug court have a substantially higher risk of using crack cocaine within four months, according to a new study. Because current but not past depression was associated with a higher risk of use, the study published in the journal Addiction suggests that addressing depression could reduce the number of women who fail to beat crack addiction in drug court. http://medicalxpress.com/news/2011-07-current-prior-depression-cocaine.html Psychology & Psychiatry Thu, 14 Jul 2011 11:22:34 EST news229861334 The Obama administration turned a bright spotlight on prescription painkiller abuse in April when the Office of National Drug Control Policy released a national action plan and a statement from Vice President Joe Biden. With a cover article in the July edition of the Journal of the American Dental Association (JADA), dentists focus that spotlight on themselves both as major sources of opioid drugs and as professionals with largely untapped power to recognize and reduce abuse. http://medicalxpress.com/news/2011-07-dentists-role-painkiller-abuse.html Medications Fri, 01 Jul 2011 10:33:02 EST news228735150 Just like everyone else, people with panic disorder have real stress in their lives. They get laid off and they fight with their spouses. How such stresses affect their panic symptoms hasn't been well understood, but a new study by researchers at Brown University presents the counterintuitive finding that certain kinds of stressful life events cause panic symptoms to increase gradually over succeeding months, rather than to spike immediately. http://medicalxpress.com/news/2011-06-panic-symptoms-steadily-acutely-stressful.html Psychology & Psychiatry Mon, 20 Jun 2011 15:56:34 EST news227804111
