ADHD and other mental issues are under-diagnosed in dysfunctional or toxic families, and of course exist in very stable caring families, so I would be very curious in which data link the very different symptoms you cite directly to trauma. It feels like going back to the era of shaming mothers for autism.
I'm not saying these 3 linked issues are caused by childhood trauma, but that they are diagnosed because of the overlap of symptoms.
This is vaguely among experts (for autism and emotional instability): https://pmc.ncbi.nlm.nih.gov/articles/PMC11724683
This is not ruling out a causal link in the opposite direction, that autism increases vulnerability to traumata.
And while researching case reports on child abuse, i couldn't help to notice that many cases do - indeed - start with an autism diagnosis and only escalate later, example: https://pmc.ncbi.nlm.nih.gov/articles/PMC11886450/
While its true that parents don't cause autism... they can surely cause the diagnosis. Extra bad because it delays appropriate treatment.
I mean at this point we should just grab the first person to post an "it's not environmental" comment and find out who he works for.
