Post-traumatic stress disorder is a mental health condition that develops in some people who have witnessed a scary, shocking, or terrifying event or experienced emotional and psychological trauma.

To diagnose post-traumatic stress disorder in adults, all of the following symptoms must be present for at least 1 month: at least one avoidance symptom, or at least one re-experiencing symptom, or at least two arousal and reactivity symptoms.

In the diagnosis of PTSD, the physician is more likely to undergo a physical test to check for medical problems and to conduct a psychological evaluation.

Treatment of PTSD includes various types of psychotherapy as well as medications to manage symptoms.
