Complex trauma

What is complex trauma?

Complex trauma (also called complex PTSD, CPTSD, or C-PTSD) is a condition that can develop after prolonged or repeated distressing events that are hard to escape, such as ongoing abuse. On top of the symptoms of ordinary post-traumatic stress disorder, it brings problems with emotions, self-image, and relationships. The World Health Organization added it to the ICD-11 in 2019.

How does complex trauma develop?

Complex trauma develops after prolonged or repeated trauma that is hard to escape. What sets it apart from ordinary PTSD is the nature of the trauma itself. Psychiatrist Chris Brewin describes complex PTSD in BJPsych Advances (2020) as a disorder that can develop after exposure to an event or series of events “of an extremely threatening or horrific nature, usually prolonged or repeated and from which escape is difficult or impossible”. Think of ongoing violence, childhood abuse, or captivity. Not one shock, but something that kept going.

What are the symptoms of complex trauma?

Under the ICD-11, complex PTSD is made up of six groups of symptoms. The first three are those of ordinary PTSD; the last three are added on top.

• Re-experiencing the trauma in nightmares or flashbacks.
• Avoiding anything that recalls the trauma.
• A persistent sense of threat, tense and easily startled.
• Problems with emotions, which surge too strongly or flatten out completely.
• A negative self-image, feeling small, defeated, or worthless.
• Difficulty with relationships, trouble forming and keeping connection.

A familiar picture: someone who lived through years of unsafety as a child seems to function fine on the surface, but keeps hitting the same wall of distrust and self-blame in relationships. That pattern, not one memory, is where complex trauma becomes visible.

What is the difference between complex PTSD and ordinary PTSD?

The difference is that complex PTSD carries three extra symptom groups on top of ordinary PTSD: problems with emotions, self-image, and relationships. The biggest misunderstanding is that complex PTSD is simply “worse PTSD”, and that is not quite right. Brewin stresses that in the ICD-11 you get either PTSD or complex PTSD, not both at once. The distinction is not about severity but about that extra layer that lingers after prolonged trauma. A one-off accident tends to lead to ordinary PTSD, years of unsafety more often to the complex form.

What complex trauma does to closeness and trust

Of the three symptoms that set complex PTSD apart from ordinary PTSD, one touches intimacy directly: the lasting difficulty with relationships. Brewin names “persistent difficulties in sustaining relationships” as one of the core features. In practice that often comes down to a body that reads closeness as danger, even when the mind knows nothing is wrong.

That makes sex and touch complicated in a way that has little to do with technique. Someone can long for contact and shut down the moment it gets truly close. Touch that reassures one person can set off the old alarm bells in someone with complex trauma. This is not unwillingness and not a lack of attraction. It is a nervous system that once learned that close was not safe, and that does not let go of that lesson easily.

The way back happens in small steps, not through a glossary or a single evening. What helps is a slow pace, a sense of what comes next, and the freedom to stop at any moment. Anyone who gets stuck here should talk it over with a therapist who works with trauma. A good intimate experience cannot replace therapy; at most it can give a taste of what safe contact feels like.

Where do you find help for complex trauma?

If you recognize yourself in this, your doctor is the first step, because complex trauma is a diagnosis that belongs in the consulting room, not on a glossary page. Thuisarts.nl explains that talking with a psychologist or psychotherapist, and treatments like EMDR, help you process what happened. I am a gigolo, not a therapist, and nothing on this page replaces that conversation. What I can do is talk about it calmly and think with you about what makes intimacy feel safe for you again, at your own pace.
