Host: What is Post-traumatic Stress Disorder?
Dr. Hayley Sherwood: Post-traumatic Stress Disorder or PTSD is an anxiety disorder that can develop after exposure to a terrifying event or an ordeal, in which serious physical harm occurred or was threatened. The person who develops PTSD maybe the one who was harmed or one who witnessed a harmful event or the harm may have happened to a loved one. People with PTSD may startle easily, feel emotionally numb, lose interest in things they previously enjoyed, have trouble feeling affectionate, be irritable, become aggressive or violent, avoid the situation that remind them of the event or experience flashbacks in which they repeatedly relive the event during the day or in nightmares.
PTSD symptoms usually begin within three months of the incident, but occasionally emerge years afterward. They must last more than one month to be considered PTSD. The course of PTSD varies. Some people recover within six months while others have symptoms that last much longer or become chronic. 1
