Contrary to popular misconceptions, Post-Traumatic Stress Disorder (PTSD) and Acute Stress Disorder (or Reaction) are not typical responses to prolonged abuse. They are the outcomes of sudden exposure to severe or extreme stressors (stressful events). Yet, some victims whose life or body have been directly and unequivocally threatened by an abuser react by developing these syndromes. PTSD is, therefore, typically associated with the aftermath of physical and sexual abuse in both children and adults.
