Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after experiencing or witnessing a terrifying or dangerous event. While it was previously classified as an anxiety disorder, it is now considered a "trauma- and stressor-related disorder". It's estimated that 3.9% of the world's population has experienced PTSD at some point in their lives. Although approximately 70% of adults globally experience a potentially traumatic event, only a minority develop PTSD. Women are more likely to develop PTSD than men.
Symptoms of PTSD can include re-experiencing the event through flashbacks, nightmares, and intrusive memories, as well as avoidance of reminders of the trauma. Negative thoughts and feelings, such as feeling detached from others, losing interest in activities, and having trouble concentrating, are also common. PTSD can also manifest as hyperarousal, including irritability, difficulty sleeping, and feeling constantly on guard. While symptoms usually begin within 3 months of the traumatic event, they can sometimes emerge later. PTSD can affect a person's ability to work, perform day-to-day activities, and maintain relationships. Effective treatments are available to reduce or eliminate symptoms.
