Post-Traumatic Stress Disorder (PTSD)

The Post-Traumatic Stress Disorder (PTSD) topic includes research on the causes, diagnosis, prevention, and treatment of PTSD, a disorder that some people develop after they experience or witness a shocking, traumatic, or dangerous event.

Genetics, neurobiology, risk factors, and personal factors may affect whether someone develops PTSD after a traumatic event. Most people who experience a traumatic event will not develop PTSD.
