What is PTSD?
It is an anxiety disorder that can develop after exposure to a terrifying event or ordeal in which grave physical harm occurred or was threatened. Traumatic events that can trigger PTSD include violent personal assaults such as rape or mugging, natural or human-caused disasters, accidents, or military combat. PTSD can be extremely disabling.

Signs & Symptoms
People with PTSD have persistent frightening thoughts and memories of their ordeal and feel emotionally numb, especially with people they were once close to. They may experience sleep problems, feel detached or numb, or be easily startled

Treatment
In general, two types of treatment are available for an anxiety disorder-medication and specific types of psychotherapy (sometimes called "talk therapy"). Both approaches can be effective for most disorders. The choice of one or the other, or both, depends on the patient's and the doctor's preference, and also on the particular anxiety disorder. For example, only psychotherapy has been found effective for specific phobias (fear of spiders, fear of flying, etc.). When choosing a therapist, you should find out whether medications will be available if needed.
