Quick answer
What is Complex PTSD?
Complex post-traumatic stress disorder (complex PTSD or CPTSD) is a condition that can develop after experiencing prolonged, repeated, or ongoing traumatic events — particularly ones that are difficult or impossible to escape, and often occurring over a long period, such as childhood abuse or neglect, long-term domestic abuse, or repeated exposure to traumatic situations. It includes the core features of post-traumatic stress disorder (PTSD) — such as reliving the trauma (flashbacks and nightmares), avoiding reminders, feeling constantly on edge (hypervigilance), and being easily startled — but, in addition, it involves further difficulties that reflect the prolonged nature of the trauma: problems with managing and regulating emotions (such as intense or overwhelming feelings, or feeling emotionally numb), a persistently negative sense of self (such as deep feelings of worthlessness, shame, or guilt), and difficulties in relationships (such as finding it hard to trust others or feel close to them).
- How it is treated: Complex PTSD is treated with psychological therapy, usually delivered by mental-health professionals experienced in trauma, and often over a longer period and in a more phased way than treatment for PTSD from a single event, reflecting its complexity.
- Self-care: Engaging with trauma-experienced therapy (often longer-term and phased), learning skills to manage overwhelming emotions, building safety and stability, self-care and grounding techniques, treating any coexisting conditions, and support from trusted people all help.
- When to seek help: See a GP about symptoms of PTSD (flashbacks, nightmares, being on edge) together with ongoing difficulties managing emotions, a persistently negative sense of self, and relationship difficulties, especially after prolonged trauma — complex PTSD is treatable with specialist support.
What it is
Complex post-traumatic stress disorder (complex PTSD or CPTSD) is a condition that can develop after experiencing prolonged, repeated, or ongoing traumatic events — particularly ones that are difficult or impossible to escape, and often occurring over a long period, such as childhood abuse or neglect, long-term domestic abuse, or repeated exposure to traumatic situations. It includes the core features of post-traumatic stress disorder (PTSD) — such as reliving the trauma (flashbacks and nightmares), avoiding reminders, feeling constantly on edge (hypervigilance), and being easily startled — but, in addition, it involves further difficulties that reflect the prolonged nature of the trauma: problems with managing and regulating emotions (such as intense or overwhelming feelings, or feeling emotionally numb), a persistently negative sense of self (such as deep feelings of worthlessness, shame, or guilt), and difficulties in relationships (such as finding it hard to trust others or feel close to them). These additional difficulties can be pervasive and long-standing, and complex PTSD can significantly affect many areas of a person's life. It is important to recognise that these are understandable responses to prolonged trauma, not personal failings, and — crucially — that complex PTSD is treatable, though it often needs longer-term, specialist support than PTSD from a single event.
How it is treated
Complex PTSD is treated with psychological therapy, usually delivered by mental-health professionals experienced in trauma, and often over a longer period and in a more phased way than treatment for PTSD from a single event, reflecting its complexity. A widely used approach involves phases: first, establishing safety, stability, and skills for managing overwhelming emotions and symptoms (which is important before processing the trauma); then, where appropriate, working through the traumatic memories using trauma-focused therapies (such as trauma-focused CBT or EMDR); and, throughout, working on the difficulties with self-worth and relationships and building a sense of safety and connection. A trusting, consistent therapeutic relationship is especially important. Treating any coexisting conditions (such as depression, anxiety, or difficulties with substances or self-harm) is part of care, and medication is sometimes used to help with specific symptoms or coexisting conditions. Support for safety (particularly if the person is still in a harmful situation) is a priority. Because recovery takes time, patience, compassion, and ongoing support matter, and many people improve significantly with the right help. The reassuring message is that complex PTSD is an understandable response to prolonged trauma, not a personal weakness, and that it is treatable with specialist, often longer-term, trauma-focused support — so seeking help from services experienced in trauma is worthwhile.
