Anxiety sensitivity, or the fear of feeling anxious, may put people who are already above-average worriers at risk for depression, according to Penn State researchers. Understanding how sensitivity to anxiety is a risk factor for depression may make anxiety sensitivity a potential target for treating depression in the future. http://www.physorg.com/news178868238.html Medicine & Health Tue, 01 Dec 2009 06:30:01 EST news178868238 Breathing carbon dioxide can trigger panic attacks, but the biological reason for this effect has not been understood. A new study by University of Iowa researchers shows that carbon dioxide increases brain acidity, which in turn activates a brain protein that plays an important role in fear and anxiety behavior. http://www.physorg.com/news178374999.html Medicine & Health Wed, 25 Nov 2009 12:37:43 EST news178374999 It is well known that fear memories are permanent. However, a recent paper in Science, evaluated by three Faculty Members for F1000, reports an extraordinary finding that supports the use of a drug to control recollections of traumatic incidents. http://www.physorg.com/news176990269.html Medicine & Health Mon, 09 Nov 2009 11:58:15 EST news176990269 Researchers have discovered that a primitive region of the brain responsible for sensorimotor control also has an important role in regulating emotional responses to threatening situations. This region appears to work in concert with another structure called the amygdala to regulate social and emotional behavior. http://www.physorg.com/news175348250.html Medicine & Health Wed, 21 Oct 2009 13:00:02 EST news175348250 Depression, anxiety disorders and sexual trauma have all been implicated as risk factors in lower urinary tract symptoms (LUTS) such as incontinence and overactive bladder. The exact nature of these associations is unknown. In a study published online in The Journal of Urology, researchers from the Division of Urology, Virginia Commonwealth University School of Medicine and the Hunter Holmes McGuire Veterans Affairs Hospital, Richmond, Virginia, explored the possible association of LUTS with those factors. http://www.physorg.com/news175235643.html Medicine & Health Tue, 20 Oct 2009 06:00:01 EST news175235643 New research shows that streptococcal infection does not appear to cause or trigger Tourette syndrome or obsessive-compulsive disorder (OCD).
