What Distinguishes Complex PTSD from PTSD?
Traumatic experiences can be devastating to those who are exposed to them. They can lead to significant mental health problems and changes in how a person functions and copes—even long after the trauma has passed. Posttraumatic Stress Disorder (PTSD) and Complex PTSD (CPTSD) are 2 types of diagnoses people may be given, based on symptoms that result from significant emotional and/or physical trauma.
Generally speaking, PTSD can develop after a single traumatic event that is life-threatening—or perceived to be—by the person who experiences it. Common examples of such situations include:
- Military combat
- Being in a destructive natural disaster
- Sexual assault
- Being held at gunpoint during a robbery
- A prisoner of war
- Subjected to torture
- Kidnapped
- Living in a war-torn area
- A victim of human trafficking
- Abused by a domestic partner over an extended period of time
Symptoms in PTSD and Complex PTSD
Right now, the most current version of the Diagnostic and Statistical Manual (DSM-V) does not separate PTSD from CPTSD in its classifications; however, the ICD-11 (International Classification of Diseases) identifies these as 2 separate conditions. While both PTSD and CPTSD share some of the same symptoms, there are specific characteristics in complex PTSD that are not seen in regular PTSD. To be diagnosed with PTSD, a person must have significant problems in functioning due to the following core symptoms that last for at least several weeks:- Have nightmares or flashbacks during which the fear of the traumatic event is vividly re-experienced
- Avoidance of activities, situations—or even thoughts and memories—of the traumatic event
- Being in a state of hypervigilance or being easily startled because of an ongoing perceived sense of threat (even though the traumatic event has passed)
- Problems controlling their emotions
- Believe they are worthless or a failure and inferior to others
- Have feelings of profound shame and guilt related to the traumatic event that distorts their perspective of themselves and the traumatic event(s)
- Have difficulty getting close to others and sustaining relationships
