What is Post Traumatic Stress Disorder (PTSD)?
PTSD is an anxiety disorder. It is caused by a major physical or emotional trauma e.g., injury, assault, being in a disaster where there are many casualties. It usually occurs at least one month after the traumatic event. The patient can experience images or memories of the event, and these can recur. Nightmares, inability to sleep, and guilt are common. Often mood is low and depression can develop. PTSD usually settles with time; but in some cases, medical treatment such as counselling or other talking therapy may be required.view glossary
