PTSD is a disorder in which a person has difficulty recovering after experiencing or witnessing a terrifying event. This disorder usually develops in individuals who have experienced a traumatic or shocking event, but the event doesn't have to be dangerous.

The individual experiences symptoms within three months of the event, but these symptoms can also occur later.

Signs & Symptoms

  1. Constantly on guard for danger, sleep disturbances, difficulty concentrating, irritability, feeling detached

  2. Flashbacks or bad dreams (related to the event), avoidance, hyperarousal, hyperreactivity, cognition and mood changes
