What Is C-PTSD? What You Need to Know About Complex PTSD
What is C-PTSD? Complex PTSD follows prolonged or repeated trauma and adds emotional dysregulation, negative self-image and relationship difficulties. Learn signs and treatment.
C-PTSD (complex post-traumatic stress disorder) is a condition recognized in the ICD-11 that develops after prolonged or repeated trauma from which escape was difficult, such as childhood abuse, domestic violence, trafficking or captivity. It includes core PTSD symptoms (re-experiencing, avoidance, sense of threat) plus disturbances in self-organization: difficulty regulating emotions, a deeply negative self-concept (shame, worthlessness) and persistent relationship difficulties.
Key takeaways
- C-PTSD is in the WHO’s ICD-11; the U.S. DSM-5-TR does not list it separately.
- It usually follows chronic, interpersonal trauma, often in childhood.
- Emotional dysregulation, shame and relationship difficulties are key features.
- It is often misdiagnosed as borderline personality disorder, depression or anxiety.
- Phased, trauma-focused therapy is effective.
Some trauma is a single event: an accident or an assault. Other trauma is a climate: years of abuse, neglect, violence or control, often beginning in childhood, with no way out. People who grow up or live in these conditions can develop symptoms that go beyond classic PTSD, shaping how they feel about themselves and relate to others.
This guide answers what is C-PTSD, its symptoms, how it differs from PTSD, causes and treatment. See also PTSD treatment and hypervigilance.
What is C-PTSD?
Complex PTSD was formally added to the World Health Organization’s ICD-11 in 2019. Diagnosis requires all core PTSD symptoms plus three additional areas called disturbances in self-organization (DSO):
- Emotional dysregulationIntense emotions, difficulty calming down, or emotional numbness and dissociation.
- Negative self-conceptPersistent shame, guilt, worthlessness or feeling permanently damaged.
- Relationship difficultiesTrouble trusting, feeling close, or staying in relationships.

How C-PTSD is treated
Safety and stabilization
Building safety, coping skills and emotional regulation (for example, DBT-informed skills).
Trauma processing
Trauma-focused therapies such as CPT, prolonged exposure, EMDR or STAIR-plus-exposure approaches, at a manageable pace. See EMDR.
Integration and reconnection
Rebuilding self-worth, relationships and meaning.
Medication support
SSRIs or SNRIs for PTSD symptoms, depression and anxiety; other medications for sleep and nightmares.
Why C-PTSD is often missed
C-PTSD shares features with borderline personality disorder, depression, anxiety, ADHD and dissociative disorders. A trauma-informed evaluation that asks about lifetime trauma helps ensure an accurate diagnosis and the right treatment.
