PTSD Study Could Lead to New Therapies, Screenings
Why do some persons succumb to post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? UCLA scientists have linked two genes involved in serotonin production to a higher risk of developing PTSD. Published in the online edition of the Journal of Affective Disorders, the findings suggest that susceptibility to PTSD is inherited, pointing to new ways of screening for and treating the disorder.
Affecting about 7 percent of Americans, PTSD has become a pressing health issue for a large percentage of war veterans returning from Iraq and Afghanistan. The UCLA team’s discovery could be used to help screen persons who may be at risk for developing PTSD.
