Effects of PTSD
PTSD, or post traumatic stress disorder, is a mental illness triggered by an outside event. PTSD is more simply explained as a state in which one can't stop remembering said event.
It can effect one's ability to adapt to life after they experience the traumatic event.
Effect on troops
PTSD wasn't fully identified until after the Vietnam war, when 1.7 million U.S. troops were effected or had symptoms. Only 6% of troops suffered PTSD due to a physical injury.
Effect on civilians
About 60% of civilian men and 50% of civilian women are effected by some sort of PTSD, be it minor or major, in their lifetime. About 75% of civilians who had PTSD also had another psychiatric disorder.
Aftereffect on troops
Military personnel often have trouble living a normal life after service. New programs that promote more job opportunities and psychiatric help are now being instated in society.
