MEDICAL DICTIONARY
Post-traumatic stress : An anxiety disorder that develops in some individuals who have had major traumatic experiences. The person is typically numb at first but later has symptoms including depression , excessive irritability, guilt (for having survived while others died), recurrent nightmares, flashbacks to the traumatic scene, and overreactions to sudden noises.
Post-traumatic stress became known in the 70s due to the adjustment problems of some Vietnam veterans. It was first listed as a diagnostic category by the American Psychiatric Association in 1980. Although the name "post-traumatic stress" was new, the condition was not. It was known as "shell shock" in World War I and "battle fatigue" during World War II.
