Post Traumatic Stress Disorder or PTSD is a disorder that can develop after a person has experienced or witnessed a traumatic or terrifying event such as a sexual or physical assault,  an accident, a death of a loved one, war, or natural disaster.

People with PTSD have difficulty recovering from traumatic events. The condition may last months or years, with triggers that can bring back memories of the trauma along with intense emotional and physical reactions.

Symptoms may include nightmares or unwanted memories of the trauma, anxiety, depression, and more. 

Treatment includes trauma-focused psychotherapy and medications to manage symptoms.
