Post-traumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is an anxiety disorder that develops after a traumatic event. PTSD has also been called "shell shock" or "battle fatigue."
The exact cause of PTSD is unknown. PTSD is triggered by exposure to a traumatic event. Situations in which a person feels intense fear, helplessness, or horror are considered traumatic. PTSD has been reported in people who experienced:
- Physical assault
- Natural disaster such as earthquakes, hurricanes, or fires
- Sexual abuse
- Motor vehicle accidents
- Animal attack
Researchers are studying how problems with synapses in the brain may be linked to PTSD.
