Post-traumatic Stress Disorder

Post-traumatic stress disorder, or PTSD, is an anxiety disorder that stems from a life-threatening event or psychological trauma. PTSD can manifest as nightmares, intense remembrances of the event, challenges in falling or staying asleep, feelings of unreasonable anger, and constant edginess. Sufferers often avoid situations that may produce thoughts or recollections of the traumatic event.

Although PTSD is often associated with soldiers, military, police officers, and other emergency personnel involved in life-threatening situations, the disorder can be triggered by any overwhelming experience. Chances for developing it are greatest if an incident is extreme, long-lasting, or repeated over time. Premeditated, human-inflicted trauma, such as rape or physical attack, tends to be more closely linked to PTSD than impersonal accidents and disasters. The level to which the distressing incident was unforeseen and out of a person’s control also plays a role.
