Giving birth can cause post-traumatic stress disorder

New research by psychologist Dr Stephen Joseph at the University of Warwick reveals that women who experience traumatic childbirth can develop symptoms of post-traumatic stress disorder (PTSD), a serious condition of anxiety usually associated with events like wars and assaults. Although health workers and psychologists are increasingly aware of postnatal depression, post-traumatic stress disorder goes widely unrecognised. Some PTSD symptoms are very similar to those experienced by those with postnatal depression, so health professionals sometimes misdiagnose the condition. However, the conditions are distinct and women with PTSD often go undetected by health workers as this is not a condition that is routinely screened for.

Intrusive emotional memories make rats forget recently learned information

People who undergo emotional trauma, such as wartime combat, typically have disturbing memories of experiences that can haunt them for the rest of their lives. These intense emotional memories often intrude into their daily lives, interfering with their ability to concentrate and learn new information. Researchers at the University of South Florida and James A. Haley Veterans' Hospital have shown for the first time that a remote, fear-provoking memory disrupts the ability of rats to remember new information ? a symptom common in people with post-traumatic stress disorder (PTSD). The animal model they developed may eventually lead to improved drug treatments for people with anxiety disorders such as PTSD.
