Posttraumatic Stress Disorder (PTSD)

All children and adolescents experience stressful events which can affect them both emotionally and physically. Their reactions to stress are usually brief, and they recover without further problems. A child or adolescent who experiences a catastrophic event may develop ongoing difficulties known as posttraumatic stress disorder (PTSD). A child’s risk of developing PTSD is related to the seriousness of the trauma, whether the trauma is repeated, the child’s proximity to the trauma, and his or her relationship to the victim(s).

Children with PTSD avoid situations or places that remind them of the trauma. They may also become less responsive emotionally, depressed, withdrawn, and more detached from their feelings.

A child with PTSD may re-experience the traumatic event by:

  • Having frequent memories of the event, or in young children, play in which some or all of the trauma is repeated over and over
  • Have upsetting and frightening dreams
  • Acting or feeling like the experience is happening again
  • Developing repeated physical or emotional symptoms when the child is reminded of the event

Children with PTSD may also show the following symptoms:

  • Worry about dying at an early age
  • Losing interest in activities
  • Having physical symptoms such as headaches and stomachaches
  • Showing more sudden and extreme emotional reactions
  • Having problems falling or staying asleep
  • Showing irritability or angry outbursts
  • Having problems concentrating
  • Acting younger than their age
  • Showing increased alertness to the environment
  • Repeating behavior that reminds them of the trauma.
