How Common is PTSD in Adults?

Posttraumatic stress disorder (PTSD) can occur after you have been through a trauma. A trauma is a shocking and dangerous event that you see or that happens to you. During this type of event, you think that your life or others' lives are in danger.

Going through trauma is not rare. About 6 of every 10 men (or 60%) and 5 of every 10 women (or 50%) experience at least one trauma in their lives. Women are more likely to experience sexual assault and child sexual abuse. Men are more likely to experience accidents, physical assault, combat, disaster, or to witness death or injury.

PTSD can happen to anyone. It is not a sign of weakness. A number of factors can increase the chance that someone will develop PTSD, many of which are not under that person's control. For example, if you were directly exposed to the trauma or injured, you are more likely to develop PTSD.
