Trauma -- What Is It?

Trauma includes emotional as well as physical experiences and injuries. Emotional injury is essentially a normal response to an extreme event. It involves the creation of emotional memories, which arise through a long-lasting effect on structures deep within the brain. The more direct the exposure to the traumatic event, the higher the risk for emotional harm. Thus in a school shooting, the student who is injured probably will be most severely affected emotionally. And the student who sees a classmate shot, even killed, probably will be more emotionally affected than the student who was in another part of the school when the violence occurred. But even second-hand exposure to violence can be traumatic. For this reason, all children and adolescents exposed to violence or a disaster, even if only through graphic media reports, should be watched for signs of emotional distress.

How Children and Adolescents React to Trauma

Reactions to trauma may appear immediately after the traumatic event or days and even weeks later. Loss of trust in adults and fear of the event occurring again are responses seen in many children and adolescents who have been exposed to traumatic events. Other reactions vary according to age:

For children 5 years of age and younger, typical reactions include a fear of being separated from the parent, crying, whimpering, screaming, immobility and/or aimless motion, trembling, frightened facial expressions and excessive clinging. Parents may also notice children returning to behaviors exhibited at earlier ages (these are called regressive behaviors), such as thumb-sucking, bedwetting, and fear of darkness. Children in this age bracket tend to be strongly affected by the parents' reactions to the traumatic event.

Children 6 to 11 years old may show extreme withdrawal, disruptive behavior, and/or inability to pay attention. Regressive behaviors, nightmares, sleep problems, irrational fears, irritability, refusal to attend school, outbursts of anger and fighting are also common in traumatized children of this age. Also the child may complain of stomach aches or other bodily symptoms that have no medical basis. School work often suffers. Depression, anxiety, feelings of guilt and emotional numbing are often present as well.

Adolescents 12 to 17 years old are likely to exhibit responses similar to those of adults, including flashbacks, nightmares, emotional numbing, avoidance of any reminders of the traumatic event, depression, substance abuse, problems with peers, and anti-social behavior. Also common are withdrawal and isolation, physical complaints, suicidal ideation, school avoidance, academic decline, sleep disturbances, and confusion. The adolescent may feel extreme guilt over his or her failure to prevent injury or loss of life, and may harbor revenge fantasies that interfere with recovery from the trauma.

Some youngsters are more vulnerable to trauma than others, for reasons scientists don't fully understand. It has been shown that the impact of a traumatic event is likely to be greatest in the child or adolescent who previously has been the victim of child abuse or some other form of trauma, or who already had a mental health problem. And the youngster who lacks family support is more at risk for a poor recovery.
