FORT HOOD, Texas (KXAN) — According to authorities, the shooter at Fort Hood’s military post took his own life and three others while undergoing diagnostic testing for Post Traumatic Stress Disorder.
PTSD can occur after an individual has been through a traumatic or devastating event.
According to the U.S Department of Veterans Affairs, PTSD can occur after witnessing combat exposure, terrorist attacks, serious accidents or natural disasters.
Lt. Gen. Mark A. Milley, senior officer on the post, said the shooter Ivan Lopez was not officially diagnosed with PTSD but was undergoing diagnosis to see if he suffered from the disorder while being treated for anxiety and depression.
The U.S Department of Veterans Affairs states anxiety and depression are problems associated with PTSD.
The National Institute of Mental Health cites causes of PTSD vary from genes and complications in an individual’s brain.
Treatment for PTSD include talking to a therapist who can help the person rethink how to cope with trauma and the aftermath. Antidepressant medication is also utilized as well according to the U.S. Department of Veterans Affairs.
PTSD was attributed to shooter, Aaron Alexis, in the September 2013 Navy Yard shooting in Fort Worth, Washington.
