Post -traumatic Stress Disorder (ptsd)
|
Overview of Post -traumatic Stress Disorder (ptsd) 
Post-traumatic stress disorder (PTSD) occurs in people that have experienced extremely distressing events. Such events (natural disasters, murder, rape, war, imprisonment, torture, accidents) produce psychological stress in everyone. Some people, however, do not recover normally from confronting these situations. PTSD occurs when someone frequently re-experiences or re-lives the trauma and associated symptoms. The symptoms may begin right after the event or may develop months or years later.
Causes of Post -traumatic Stress Disorder (ptsd)
Exposure to an overwhelming event is the primary cause of PTSD. The event is sudden, unexpected, bloody or extremely brutal. Prolonged and chronic stress develop from the event. There is often lack of social support to the individual who has developed PTSD.
Signs and Symptoms of Post -traumatic Stress Disorder (ptsd)
PTSD produces recurrent, intrusive, life-like and distressing recollections of the past event. There are often recurrent dreams relating to the event and a sense of reliving the event (flashbacks). PTSD leads to chronic anxiety, insomnia, difficulty concentrating and memory impairment. There may develop a sense of personal isolation and diminished interest in activities. People often demonstrate avoidance of activities that recall memories and past emotions. Emotional changes are common, including irritability, restlessness, tremulousness, explosive outbursts of behavior, a deadening of feelings and painful guilt feelings.
