Complex PTSD (C-PTSD) is what can develop when trauma isn’t a single event but something prolonged, repeated, or inescapable. If standard descriptions of PTSD have never quite fit your experience, C-PTSD may explain why.
What causes complex PTSD
While PTSD often follows a single traumatic event, C-PTSD typically arises from repeated or prolonged trauma, especially where escape felt impossible — for example childhood abuse or neglect, domestic violence, trafficking, or prolonged captivity. It’s now recognised in the international diagnostic system (ICD-11) as a distinct condition.
How it differs from PTSD
C-PTSD includes the core features of PTSD — intrusion, avoidance and hyperarousal (see PTSD symptoms) — plus three additional areas often described as “disturbances in self-organisation”:
- Emotional dysregulation — intense, hard-to-manage emotions, or feeling emotionally numb.
- Negative self-concept — persistent feelings of worthlessness, shame or guilt, often carried since childhood.
- Relationship difficulties — trouble feeling close to others, or a pattern of unstable relationships.
Many people with C-PTSD have spent years being treated for depression, anxiety or a personality disorder without the underlying trauma being recognised.
Why an accurate assessment matters
Because C-PTSD overlaps with other conditions, a careful assessment is important — it shapes the treatment. A psychiatrist can distinguish C-PTSD from conditions it resembles (such as borderline personality disorder or bipolar disorder) and make sure you get trauma-informed care rather than treatment for the wrong target.
Treatment and recovery
C-PTSD is treatable, though recovery is usually a longer, phased process. Effective approaches include:
- Trauma-focused psychotherapy — including approaches like trauma-focused CBT and EMDR, often within a phased model that builds safety and stability first.
- Medication — can help manage co-occurring depression, anxiety or sleep difficulties, prescribed and monitored by a doctor.
- A strong therapeutic relationship — safety and trust are themselves part of the treatment.
