Nearly 70% of people will experience some form of trauma in their lifetime, and a growing understanding of the long-term effects is reshaping how mental health professionals approach treatment. While post-traumatic stress disorder (PTSD) has long been recognized, experts are increasingly focusing on a more complex and debilitating condition: complex PTSD (C-PTSD). This shift in understanding, formally acknowledged in 2018, is leading to more effective interventions for individuals who haven’t responded to traditional therapies.
C-PTSD isn’t simply PTSD with more symptoms; it arises from prolonged or repeated trauma, often experienced in relationships where escape is tough. This can include childhood abuse, domestic violence, or being held captive. The core symptoms of PTSD – intrusive memories, avoidance, negative alterations in cognition and mood, and alterations in arousal and reactivity – are present in C-PTSD, but are accompanied by significant difficulties in three additional areas: difficulty with emotional regulation, a deeply negative self-view, and challenges in maintaining relationships. These added layers can make C-PTSD particularly challenging to treat.
The 2018 Breakthrough: Recognizing Complex Trauma
The formal recognition of C-PTSD as a distinct condition in 2018 was a pivotal moment in the field of mental health. Prior to this, many individuals struggling with the aftermath of chronic trauma were misdiagnosed with PTSD, or their symptoms were attributed to other conditions. This misdiagnosis often led to ineffective treatment, as standard cognitive behavioral therapy (CBT) – a common treatment for PTSD – doesn’t always address the core issues underlying C-PTSD.
According to research, a significant number of people previously diagnosed with PTSD may actually be living with C-PTSD. This realization is prompting clinicians to re-evaluate past diagnoses and tailor treatment plans accordingly. The International Classification of Diseases (ICD-11) by the World Health Organization (WHO) included C-PTSD as a distinct diagnosis in 2018, solidifying its recognition within the medical community. The International Society for Traumatic Stress Studies (ISTSS) has also published guidelines on the diagnosis and treatment of C-PTSD in adults.
Why Traditional Therapy Sometimes Falls Short
Standard CBT for PTSD often focuses on processing traumatic memories and developing coping mechanisms. While helpful for some, this approach can be overwhelming and even re-traumatizing for individuals with C-PTSD, whose difficulties with emotional regulation and self-perception can hinder their ability to engage effectively in the process.
“Many of the patients who couldn’t be treated with standard cognitive behavioral therapy are now being found to have complex PTSD,” explains the source material. This highlights the need for a different therapeutic approach, one that prioritizes building a foundation of emotional stability and relational skills before tackling the traumatic memories themselves.
A New Approach: Building Emotional and Relational Skills
Treatment for C-PTSD typically begins with a focus on developing skills in emotional regulation and improving interpersonal relationships. This might involve therapies like dialectical behavior therapy (DBT), which teaches skills for managing intense emotions, or schema therapy, which addresses deeply ingrained negative patterns of thinking and behaving.
The goal is to help individuals develop a stronger sense of self-worth, learn to regulate their emotions, and build healthier relationships. Once these foundational skills are in place, the classic PTSD treatment approaches – such as trauma-focused CBT – can be more effectively applied.
Ongoing Research and Future Directions
Research into the genetic factors that contribute to PTSD and C-PTSD is also underway. Stanford Medicine is exploring how genetics may influence vulnerability to these conditions and inform more personalized treatment strategies.
The National Institute for Health and Care Excellence (NICE) guidelines for PTSD, originally published in 2018, are continually updated as new research emerges. A review published in the British Medical Bulletin in September 2025 summarizes the current state of evidence and ongoing debates in the treatment of PTSD and C-PTSD.
As understanding of complex trauma continues to evolve, it’s crucial for individuals experiencing these challenges to seek support from qualified mental health professionals who are trained in the latest evidence-based treatments. Early intervention and appropriate care can significantly improve outcomes and help individuals reclaim their lives after trauma.
