Symptoms of Post-traumatic Stress Disorder (PTSD)

For most people, PTSD starts within about 3 months of the traumatic event. For some people, signs of PTSD don't show up until years later. PTSD can happen to anyone at any age. Even children can have it. Some people get better within 6 months, while others may have the disorder for much longer. Symptoms of PTSD may vary in frequency and intensity over time, and may fall into 3 categories:

  • Re-experiencing the event:
    • Dreams or nightmares
    • Intrusive memories
    • Flashbacks
    • Anxious reactions to reminders of the event
  • Avoidance:
    • Avoidance of external reminders of the event, such as places, situations, or people that can trigger memories
    • Efforts to avoid feelings, thoughts, memories related to the event
  • Negative changes in mood and cognition related to trauma including detachment, numbness, difficulties remembering relevant details of the trauma
  • Arousal:
    • Difficulty falling or staying asleep
    • Anger and irritability
    • Difficulty concentrating or maintaining attention
