Post traumatic stress disorder (PTSD) is a mental health condition that may develop after experiencing or witnessing a traumatic event such as violence, abuse, natural disasters, serious accidents, combat, or other life-threatening situations. Not everyone who experiences trauma develops PTSD, and symptoms vary widely.
It is normal to have fear, stress, or intrusive memories after trauma. Most people begin to recover with time; however, when symptoms persist for longer than one month, significantly interfere with daily functioning, or worsen over time, PTSD may be present.
