What is Posttraumatic Stress Disorder?

Posttraumatic Stress Disorder (PTSD) is a very common mental health disorder, affecting 8.7% of people during their lifetime. The core symptoms are:

  • re-experiencing the trauma psychologically (flashbacks and nightmares)
  • avoiding reminders of the trauma
  • emotional numbing
  • hyperarousal (irritability, and being jumpy or constantly “on alert”)
