Answer:
Post traumatic stress disorder
Explanation:
Post traumatic stress disorder (PTSD) is very commonly found in people who have experienced a severely traumatic event. This is commonly seen in war veterans as a result of traumatic events. Examples include seeing a family member die, or being a part of a terrible accident.
The brain often cannot recognize it as something that actually happened, so it stops the sufferer from functioning as a normal person in society, and sufferers often have to have special care.
