Complex PTSD

Complex PTSD arises from prolonged or repetitive trauma—such as childhood adversity, domestic violence, or exposure to war or conflict—where escape is perceived as impossible. ICD-11 adds three symptom clusters to core PTSD: emotional dysregulation (intense, unstable emotions), negative self-concept (shame, guilt, worthlessness), and interpersonal difficulties (avoidance, distrust, or preoccupation with perpetrator). These manifest as chronic fatigue, dissociation, or somatic complaints like migraines or GI issues, often without explicit trauma recall.

Distinguishing it from borderline personality disorder is critical: both share emotional instability and identity issues, but C-PTSD’s emotional dysregulation stems from trauma memory, not impulsivity or fear of abandonment alone. Self-harm in C-PTSD tends to express inner pain rather than regulate interpersonal chaos. Comorbid personality traits may exist, but a trauma-focused history usually clarifies the primary diagnosis.

Functional impact often includes occupational instability, strained relationships, and medical nonadherence due to distrust or somatic focus. Screening tools can aid clinical judgment, but diagnosis requires clinician interpretation of trauma exposure and symptom clusters over time. Referral to trauma-specialized therapy is indicated when symptoms persist beyond several weeks of initial intervention.
