There is no evidence to substantiate PTSD diagnosis.
Okay, so like there is no evidence to substantiate depression, Autism, etc (like we don't have a blood test and ..."aha!"). I think the symptoms themselves, along with Criterion A, is the "evidence" enough...guess that's where I was going. But to stay on topic...
We need to stay focused on PTSD diagnosis and creating one based on what we know and what is available to us
Since I fit a few of the proposed categories (PTSD, CPTSD, and DTD), I'm not sure how it would sort out even in sub-categories. I think if working with a trauma specialist it all fits decently (or good enough) in the current DSM description. Lack of criterion A would make it a mess. The only added thought I have is a different way to word criterion A for children. Chronic neglect is felt as life threat to a young child. Witnessing chronic violence in the home wires them into chronic hypervigilence because they cannot escape. Direct abuse is obviously more likely connected to the more globalized symptoms suggested under complex trauma proposals.
I'd probably call them all
disorders of extreme stress (NOT an anxiety disorder), as a heading, and break it down into PTSD, CPTSD, DTD (specify early, developmental trauma), and DESNOS (like traumatized responses from cops after witnessing too much violence) ??? . Many people would find overlap, but that happens with a whole bunch of mental illnesses anyway.
The diagnosis option of DTD might give professionals another angle to study before diagnosing things like ADHD, ASD, and ODD (oppositional-defiant) in children. Obviously these are real issues too, but I'm always a little suspicious when a youngster has a list of like four to seven separate mental health diagnosis that all relate to nervous system and emotional dysregulation. But with DTD as a proposal, the politics involved are likely gnarly. Like do you have to prove a trauma or can you treat as trauma-informed and not just jump to assuming a kid needs to be removed from their homes? And if you dig for the trauma and find it, who pays for those treatment services? Right now most children who struggle, in any way, end up getting special education services through their school and lumped somehow into one of those categories. I don't love it. Van Der Kolk's proposal had support of the other major experts involved in the proposal process...and then DTD mysteriously did not show up in the DSM. There are a lot of unturned rocks here.
