Post-Traumatic Stress Disorder (PTSD) is an anxiety disorder that can be developed by experiencing or witnessing a one-off event, or ongoing events, that are extremely distressing or frightening.
This can be experiences such as a car crash, domestic or sexual abuse or working in a war zone. People with PTSD can relive the trauma through vivid memories and flashbacks and struggle in their daily life.
PTSD can affect people of any age, and the symptoms normally begin within the first three months after the traumatic experience.
