trauma and psychosis
the DSM-5 and ICD-11 sections for PTSD and CPTSD don’t mention psychosis, aside from “auditory pseudo-hallucinations” (attributed to dissociation, not psychosis) and differentiating flashbacks from hallucinations and hypervigilance from paranoia.
but there is a link between the two, and researchers have even proposed a subtype of PTSD, psychotic PTSD (or PTSD-SP).
not only is there psychosis caused by trauma, but there’s also trauma caused by psychosis (PTSD-PP). a person can have both trauma caused by psychosis and psychosis caused by trauma.
the difference lies in the reasons why they are experiencing the symptoms: in PTSD-PP, a person has trauma revolving around their psychotic symptoms (e.g., a person who had a psychotic episode involving the FBI spying on them through their TV is now triggered by their TV, even though they’re no longer psychotic), where in PTSD-SP, the psychosis is caused by their trauma (e.g., a person who was religiously abused now has a delusion that they’re a demon).
as someone who has both psychosis-caused trauma and trauma-caused psychosis, i’m interested to see where this research goes!
