Post traumatic stress syndrome or post- traumatic stress disorder (PTSD) is defined as a delayed reaction to an exceptionally stressful situation or a life threatening event. The delay can be as long as 6 months or even more. This disorder has gained significant attention during the past few years as more and more researches have commented on the short and long term effects of post traumatic stress disorder.

Causes of Post Traumatic Stress Disorder

Post traumatic stress disorder follows an exceptionally stressful or a catastrophic life event after a dormant period. The causative event usually is so severe that any normal person who experiences it gets affected. The stressful events could be any of the following.

Natural Calamity - e.g. Post -Tsunami, Post- Katrina, Post - Rita
War - e.g. Post - Vietnam war, Post- Gulf war
Rape
Terror - e.g. 9/11, London Bomb Blasts
Serious Accidents like train accidents and building collapse following earth quake
Traumatic death of beloved ones - e.g. Life partner, Parents, Children

The persons who survive the calamities or who witness those events get affected and start manifesting the syndrome after a couple of months. The susceptibility and severity of affliction depends on the following criteria.

The affected person should perceive the event as a dangerous one.
The affected person should feel helpless in response to the event.
The affected person should have high levels of anxiety trait.

Whenever a person perceives an event as a dangerous one, the normal response would be Fight or flight. But when the stress of the event is very severe or the situation is such a one that could not be overcome or avoided it results in post traumatic stress disorder. If the person has a high anxiety trait, the manifestation will be earlier and more severe.

The manifestations of the disorder are seen after a couple of months. The impact of the event is so much that the person who is affected, tries to avoid any stimuli reminding him of that past stressful event. In spite of it, if the person experiences the stimuli, the manifestations become more severe, with more anxiety and more arousal.

An affected person gets repeated recollection of the stressful event as Flashbacks or dreams. The person re-experiences the original trauma and gets affected both physiologically and psychologically and tries to avoid such stimuli. Repeated Re-experiences cause a behavioral change in the person. The changes could be

Psychological numbing
Amnesia of certain aspects of the stressful event
Inability to experience pleasure
Isolation
Reduced interest in activities
Sleeplessness
Agitation

Short Term Effects of PTSD

These effects are seen when the person re-experiences the past trauma as Flash backs or dreams. The short term effects of stress in PTSD are mostly physical effects.
