About Traumatic Stress
It is 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.
Traumatic exposure may be brief in duration (e.g., an automobile accident) or involve prolonged, repeated exposure (e.g., sexual abuse). The former type has been referred to as "Type I" trauma and the latter form, as "Type II" trauma.
