POST-TRAUMATIC STRESS DISORDER

Helping Children and Adolescents Cope with Violence and Disasters

Some children and adolescents will have prolonged problems after a traumatic event. These potentially chronic conditions include depression and prolonged grief. Another serious and potentially long-lasting problem is post-traumatic stress disorder (PTSD). This condition is diagnosed when the following symptoms have been present for longer than one month:

Re-experiencing the event through play or in trauma-specific nightmares or flashbacks, or distress over events that resemble or symbolize the trauma.

Routine avoidance of reminders of the event or a general lack of responsiveness (e.g., diminished interests or a sense of having a foreshortened future).

Increased sleep disturbances, irritability, poor concentration, startle reaction and regressive behavior.

Rates of PTSO identified in child and adult survivors of violence and disasters vary widely. For example, estimates range from 2% after a natural disaster (tornado), 28% after an episode of terrorism (mass shooting), and 29% after a plane crash.

The disorder may arise weeks or months after the traumatic event. PTSO may resolve without treatment, but some form of therapy by a mental health professional is often required in order for healing to occur. Fortunately, it is more common for traumatized individuals to have some of the symptoms of PTSD than to develop the full-blown disorder.

People differ in their vulnerability to PTSD, and the source of this difference is not known in its entirety. Researchers have identified factors that interact to influence vulnerability to developing PTSD.

These factors include:

• characteristics of the trauma exposure itself (e.g., proximity to trauma, severity, and duration),

• characteristics of the individual (e.g., prior trauma exposures, family history/prior psychiatric iIIness, gender women are at greatest risk for many of the most common assaultive traumas), and

• post-trauma factors (e.g., availability of social support, emergence of avoidance/numbing, hyperarousal and re-experiencing symptoms).

Research has shown that PTSD clearly alters a number of fundamental brain mechanisms. Abnormal levels of brain chemicals that affect coping behavior, learning, and memory have been detected among people with the disorder. In addition, recent imaging studies have discovered altered metabolism and blood flow in the brain as well as structural brain changes in people with PTSD.

TREATMENT OF PTSD

People with PTSD are treated with specialized forms of psychotherapy and sometimes with medications or a combination of the two.

One of the forms of psychotherapy shown to be effective is cognitive behavioral therapy, or CST. In CST, the patient is taught methods of overcoming anxiety or depression and modifying undesirable behaviors such as avoidance of reminders of the traumatic event. The therapist helps the patient examine and re-evaluate beliefs that are interfering with healing, such as the belief that the traumatic event will happen again.

Children who undergo CBT are taught to avoid "catastrophizing". For example, they are reassured that dark clouds do not necessarily mean another hurricane, that the fact that someone is angry doesn't necessarily mean that another shooting is imminent, etc. Play therapy and art therapy also can help younger children to remember the traumatic event safely and express their feelings about it.

Other forms of psychotherapy that have been found to help persons with PTSD include group and exposure therapy. A reasonable period of time for treatment of PTSD is 6 to 12 weeks with occasional follow-up sessions, but treatment may be longer depending
