What causes post-traumatic stress disorder (PTSD)?
The trigger for post-traumatic stress disorder (PTSD) is a traumatic event experienced by the person. About 10-25% of people who suffer traumatising events go on to develop PTSD. Events that can cause PTSD can include: rape and sexual abuse; wartime and combat experiences (for both soldiers and civilians); natural disasters; violent assault, terrorist attacks, hostage situations, domestic violence; accidents (car accidents, plane crashes, industrial accidents); imprisonment and torture, experiences in detention camps or concentration camps; severe neglect in childhood, and; the sudden, unexpected death of a loved one. In some cases, a person can develop PTSD despite not having experienced it directly, but through learning of a horrific event happening to a close loved one.
