Posttraumatic Stress Disorder
Captions available
The idea
Posttraumatic stress disorder can follow exposure to a traumatic event and involves intrusion symptoms, avoidance, negative mood changes, and heightened arousal.
In practice
A survivor re-experiences the event involuntarily, avoids reminders, and remains startle-prone months afterward.
Where people slip
Most people exposed to trauma do not develop the disorder. Exposure is a criterion, not a prediction.
