Reddit reviews Psychosis, Trauma and Dissociation: Emerging Perspectives on Severe Psychopathology

Cool thanks. I'm a doctoral student in clinical psych and hadn't come across those terms before, so thanks for helping me learn. That being said, based on my understanding of similar concepts and a quick literature check (see here for instance), your definitions here are a little off. Desomatization concerns a lack of physical sensation (not functioning) or numbness. De-ideation concerns a lack of awareness of thoughts and other mental activity. Quite different from what you wrote.

You might want to look into conversion disorder as well (recently redubbed 'functional neurological symptom disorder') which technically involves dissociation of motor and/or sensory functioning from awareness/voluntary control. While the DSM places it in a distinct category, the ICD lists it as a dissociative disorder, for good reason. It was one of the earliest recognized disorders to be labelled as such, back when it known as "hysteria." I highly recommend reading into the history of psychology as dissociation plays an enormous role in it. I cannot recommend this book enough. I see a 2nd editionhas just been released
