PTSD (post-traumatic stress disorder?j is a psychiatric disorder that can occur following exposure to a traumatic event that poses a serious threat to the life or physical integrity of the exposed individual or his/her close family members. Characteristic symptoms include recurrent and intrusive recollections of the traumatic event; distressing illusion as if the past traumatic event was still happening before his/her eyes; a sense of isolation; sleep disturbances; and startled reactions that occur when the person is exposed to trigger events that resemble the traumatic event. If these symptoms persist for more than one month, then the person will be diagnosed with PTSD.
If recovery from stress reactions is delayed and marked symptoms persist for more than one month, the person is suspected to have developed PTSD and needs to be referred to a mental health specialist. For reference, an evaluation scale to screen persons at high risk of PTSD, called the IES-R. IES-R is considered to be effective for evaluating post-traumatic stress symptoms in the early stages.
