@TomPinch I did read the abstract and indeed the whole paper carefully and it still makes me queasy.
We hypothesize that the traits often classified as autistic could be more accurately related to the distress and discomfort evoked by GD.
That's still an extreme statement based on one case that is still evolving. "Exacerbated", yes fine. But "more accurately related"?
The story is reminiscent of The Horse Boy, a lovely humourous documentary film about a young boy whose autism is ameliorated by a trip on horseback to visit shamans in Mongolia. (Yes really!) Some of his worst problems are relieved, he makes a friend and plays imaginary games with him, and he has a much brighter future ahead. No-one says his autism has gone away or was misdiagnosed.
It's dodgy to let a patient go away believing that all their autism has been fixed and gone away for good. Things are going nicely now but they could be in for disappointment later in life. Telling them they deifinitely don't have autism has shut down a pathway they might need later. Just where does this eagerness not be labelled autistic come from? Therapists like to feel that they have been successful but it might have been better to explain the effects of lowered stress and about traits that don't go away which the patient may always need to manage when life throws difficulties in their path.
The same weaknesses in the ADOS that the authors discuss and lead the authors to claim the patient was misdiagnosed with autism in the first place, might lead to a misdiagnosis the other way round when the patient is feeling relaxed and confident and has found ways to communicate. I'd be interested to know how consistent ADOS results are over time.
It's especially risky to give a patient the impression that transition fixed their condition. A lot has gone on in this young person's life. They've grown up and matured, presumably they've been given ways to manage the disconnect from their parents, and they have been getting years of lovely individual therapeutic support. They have friends now in an accepting group as @GCautist says. If the group falls away, if social problems and unhappiness resurface then how tempting will it be to go further along the route to transition? Having professionally confirmed to the patient that none of this is related to autism?
From the paper, stated approvingly:
In particular, we are currently witnessing the process of depathologization of transgender conditions, reflected by the new ICD diagnosis of gender incongruence (WHO, 2018).
Fantastic. We depathologise and at the same time we medicalise and we cut bits off.
