Why do some people develop post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? A new UCLA discovery may shed light on the answer.
UCLA scientists have linked two gene variants to the debilitating mental disorder, suggesting that heredity influences a person’s risk of developing PTSD. Published in the February 2015 edition of the Journal of Affective Disorders, the findings could provide a biological basis for diagnosing and treating PTSD more effectively in the future.
“Many people suffer with post-traumatic stress disorder after surviving a life-threatening ordeal like war, rape or a natural disaster,” explained lead author Dr. Armen Goenjian, a researcher at the Semel Institute for Neuroscience and Human Behavior at UCLA. “But not everyone who experiences trauma suffers from PTSD.
