The Dissociative Subtype of PTSD: Understanding It in Yourself & Others

Post-traumatic stress disorder is a complex condition that impacts a diversity of trauma survivors in a wide range of ways. Just as no two people’s experiences are the same, no two people will experience PTSD in the exact same way. As a result, clinicians recognize a number of PTSD “subtypes,” one of which is the dissociative subtype (PTSD+DS).


The dissociative subtype of PTSD is a lot more common than you may realize. About 15 million U.S. adults have PTSD, and among them, more than 14 percent have PTSD+DS.


This subtype shares many attributes with complex PTSD (C-PTSD). Studies show that people with PTSD+DS are more likely to have experienced childhood physical or sexual abuse, struggle in interpersonal relationships and experience emotion dysregulation.


When empathizing with someone who experiences PTSD+DS, or trying to make sense of your own diagnosis, it will help to understand which symptoms are most commonly associated with this condition.

Symptoms of PTSD+DS

PTSD+DS includes the core PTSD symptoms associated with any PTSD diagnosis: re-experiencing the traumatic event(s), avoiding reminders of the traumatic event(s), feeling negative emotions and struggling to feel calm or safe (hypervigilance).


However, for people with PTSD+DS, they experience notably higher levels of dissociation.


Dissociation refers to a range of symptoms that impact consciousness, including:

  • Depersonalization
  • Derealization
  • Memory disturbance
  • Disengagement
  • Time loss
  • Trance
  • Gaps in awareness and memory
  • Sensory misperception
  • Reckless or self-destructive behavior

PTSD-DS is also associated with negative (but fortunately reversible with proper treatment) changes in the brain.


Changes in the frontal cortex are heavily associated with PTSD, and even more so with PTSD+DS. This region of the brain is responsible for functions such as inhibiting the “fight-or-flight” response, processing sensory experiences and managing one’s self-perception. As such, PTSD+DS often creates a sense of detachment, which is felt between a person and their emotions, their environment and even their sense of self.


Even among people who are diagnosed with PTSD-DS, their experiences will differ based on their personality, what type of trauma(s) they’ve experienced and other mental health problems they may have.


For example, people experiencing both PTSD-DS and substance use disorder endure more depressive symptoms (suicidal thoughts, suicide attempts and drug overdoses) on average. For those who experienced childhood sexual abuse, PTSD-DS was linked to high hypervigilance, a sense of foreshortened future and sleep difficulties.

How to Help With PTSD+DS

When recovering from PTSD+DS, one should understand neuroplasticity, the brain’s ability to change and adapt based on our experiences, whether good or bad. Just as a traumatic event can alter the way our brain is wired, positive experiences (and a strong treatment plan) allow the brain to physically heal. As you improve your surroundings, you can strengthen your brain’s plasticity and thrive.


One treatment method of PTSD+DS is skills training followed by exposure-based therapy, such as cognitive processing therapy, prolonged exposure and more. Studies found that this combination leads to a reduction in dissociative symptoms throughout the trauma recovery process.


With a treatment plan that works for you, you can find recovery from PTSD+DS.
