Post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a term for certain psychological consequences of exposure to, or confrontation with, stressful experiences that the person experiences as highly traumatic.

These experiences can involve actual or threatened death, serious physical injury, or a threat to physical and/or psychological integrity.

It is occasionally called post-traumatic stress reaction to emphasize that it is a routine result of traumatic experience.
