Explore complex post traumatic stress disorder: causes, symptoms, treatment & how it overlaps with depression, ADHD, anxiety and more.
Complex post traumatic stress disorder (CPTSD or C-PTSD) is a trauma-related mental health condition that arises from prolonged, repeated, or relational trauma—often beginning in childhood or in situations where escape is difficult.
Unlike the more widely known Post‑traumatic stress disorder (PTSD), which frequently stems from a single traumatic event (such as an accident or natural disaster), CPTSD involves complex trauma—such as chronic domestic abuse, childhood neglect, ongoing violence, human trafficking, or war-zone captivity.
Key features of CPTSD include classic PTSD symptoms (flashbacks, avoidance, hyper-arousal), plus:
At the heart of CPTSD is the concept of complex trauma: trauma that is repetitive, relational (i.e., by another person), and occurs in a context of powerlessness. Examples include childhood abuse/neglect, ongoing intimate partner violence, captivity, human trafficking, or prolonged exposure to war or organised violence.
When trauma occurs early in life, it disrupts key developmental processes—attachment, self-regulation, identity formation—which increases risk for CPTSD later.
Prolonged trauma can alter brain circuits (e.g., stress response, emotional regulation), impact executive functioning, and lead to pervasive self-conceptions of helplessness or worthlessness. Social-environmental factors—such as lack of safe relationships, unstable home environments, socio-economic adversities—further elevate risk.
CPTSD often does not occur in isolation. Individuals may also develop or present with conditions like depression, anxiety disorders, ADHD, OCD, BPD, and eating disorders. These overlap conditions can compound risk and complicate treatment.
For example:
Similar to PTSD, CPTSD involves reliving traumatic memories through flashbacks or nightmares, avoiding reminders of trauma, and experiencing heightened threat responses (hypervigilance, startle).
But CPTSD goes further:
Because of the symptom overlap, CPTSD may be mis-diagnosed or co-occur with:
Because CPTSD is newly codified in ICD-11 and not yet standard in DSM-5, clinicians must carefully differentiate it from classic PTSD and other disorders. The takeaway is that CPTSD adds three extra symptom clusters (emotional regulation, self-concept, relationships) on top of PTSD criteria.
Key considerations:
Because CPTSD involves deep relational and identity wounds, treatment often follows multi-phase models:
Because CPTSD often overlaps with depression, anxiety, ADHD, OCD, eating disorders, BPD or psychosis, integrated treatment is essential. Treating only trauma without addressing, say, ADHD or eating-disorder behaviours may limit gains.
Key supportive strategies: establishing routines, physical activity, mindfulness, safe social connections, trauma-informed peer support. Education about trauma’s impact helps reduce self-blame and fosters healing.
While CPTSD may involve deeper wounds, it is treatable. With the right trauma-informed, relational approach, many individuals learn to rebuild identity, improve relationships, regulate emotions and live meaningful lives.
Understanding complex post traumatic stress disorder helps clinicians and systems recognise that many people labelled with depression, anxiety, BPD, or even schizophrenia-spectrum disorders may actually have underlying trauma histories. For example:
