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 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.
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.
