Complex PTSD (C-PTSD) develops in response to prolonged or repeated trauma, such as childhood abuse, domestic violence, or sustained neglect. It shares features with PTSD but also involves deeper difficulties with emotion regulation, identity and relationships. Specialist therapy can make a significant difference, and recovery — while often a longer journey — is absolutely possible.
See therapies that may helpComplex PTSD is a condition that can develop after exposure to prolonged, repeated trauma — particularly trauma that is interpersonal in nature and from which escape felt impossible. Common causes include childhood physical, emotional or sexual abuse, domestic abuse, trafficking, torture, and prolonged neglect.
While standard PTSD typically develops from a single traumatic event and centres on re-experiencing, avoidance and hyperarousal, C-PTSD involves these features plus additional difficulties that arise from sustained trauma exposure:
C-PTSD is recognised in the ICD-11 (the World Health Organisation's diagnostic manual) and is increasingly well understood within the therapeutic community, though it remains underdiagnosed.
Signs of complex PTSD often include the core PTSD symptoms alongside additional features:
Many people with C-PTSD have received other diagnoses — including depression, BPD, or bipolar disorder — before receiving a C-PTSD diagnosis. If you recognise these patterns and have a history of prolonged trauma, it is worth raising with a trauma-informed professional.
C-PTSD requires specialist trauma-informed therapy, delivered by a therapist with specific training and experience in complex trauma. It is not suitable for standard short-term CBT approaches, and pushing into trauma processing before adequate stabilisation can be harmful.
Effective approaches include:
Good C-PTSD therapy typically follows a phased approach: first building safety and stabilisation, then processing traumatic memories, then integration and reconnection. Do not be discouraged if early sessions focus on coping skills rather than diving into trauma — this is best practice.
If you recognise C-PTSD in yourself, finding a trauma-specialist therapist is important — not all therapists have the training required to work safely with complex trauma. When looking for a therapist, ask specifically about their experience with complex trauma or C-PTSD, and what therapeutic model they use.
The EMDR Association UK and the British Psychoanalytic Council both have directories of specialist practitioners. The NHS also offers trauma-focused therapies through IAPT and specialist services, though waiting times can be long for complex presentations.
Recovery from C-PTSD is a longer journey than recovery from single-event PTSD, and progress is rarely linear. Working with a therapist who offers consistent, boundaried, long-term support is more important than the specific modality.

PTSD typically develops from a single traumatic event and centres on intrusive memories, avoidance and hyperarousal. Complex PTSD develops from prolonged or repeated trauma and includes these features plus additional difficulties with emotion regulation, self-perception and relationships. C-PTSD is recognised in the ICD-11 but not yet in the DSM-5.
There is no single best therapy, but EMDR, trauma-focused CBT, schema therapy and somatic approaches all have good evidence. Crucially, therapy should be delivered by a trauma-specialist with experience of complex presentations, and should follow a phased approach — stabilisation before trauma processing.
Recovery from C-PTSD is possible, though it is typically a longer process than recovery from single-event PTSD. Many people achieve significant improvement in symptoms, quality of life and relationships. The goal of therapy is not necessarily to eliminate all traces of the past but to reduce its hold on the present and build a life that feels liveable.
There is significant overlap in symptoms between C-PTSD and BPD, and many people with C-PTSD have previously received a BPD diagnosis. The key difference is aetiology — C-PTSD is understood as a trauma response rather than a personality disorder. The distinction matters because the treatment approach differs.
Yes, though access varies by area. NHS IAPT services offer trauma-focused therapy, and some areas have specialist complex trauma services. Waiting times can be long. You can self-refer to IAPT in England. For complex presentations, many people access specialist therapy privately while waiting for NHS provision.
