Complex PTSD (CPTSD) differs from PTSD primarily in its origins and symptoms. While PTSD typically results from a single traumatic event, CPTSD develops due to prolonged or repeated trauma over months or years, often in situations where the victim is under the control of the perpetrator. CPTSD includes all the symptoms of PTSD along with additional issues such as difficulty with emotional regulation, an altered sense of the perpetrator (which may include a preoccupation with revenge or giving the perpetrator power), and a distorted self-concept.
