I've been talking with the other Gender Critical Autistics members and sent this in response:
"Hi Terry,
Thank you for the clarification. Apologies for the delay in responding, I was consulting with other autistic adults - there is a large group of us interested in the issue.
Though the 7.8% autism rate in the de Vries et al study is still very high, the study is now ten years old and the demographics of the cohorts at gender clinics today have changed. The Tavistock & Portman clinic's more recent figures show 35% of referrals assessed have moderate to severe autistic traits, and a further 13% with mild autistic traits. In some clinics in Australia, almost half of the patients are diagnosed with an ASD. There appears to be little explanation or appetite to find a reason for the sudden increase in autistic children referred.
"Even though it is possible, and likely, that social and/or medical transition may help to alleviate some of the difficulties related to autism" - specifically, which forms of social transition, and which medical treatments, can help to alleviate which difficulties related to autism? Autism can cause someone to have many different features and traits, and not all autistic people have all of them.
I'm also interested to see what evidence supports this claim. While it's certainly not as strong or as specific a claim as in the 2016 report, it still requires substantiation, particularly if this argument is then used to push for treatments involved in medical transition (which?) for autistic patients who may first benefit from less invasive treatment and support for their difficulties (and then, once those are resolved or those avenues have been exhausted, decide if more invasive treatments would be beneficial).
As I mentioned in my initial message, there have been many different experimental medical treatments given to autistic people with little evidence to support them, and it has resulted in medical malpractice - for example, Andrew Wakefield's experimental colonoscopies and lumbar punctures on autistic children in the late 1990s, and Mark and David Geier's attempts to cure autism with Lupron in the late 2000s. Wakefield was struck off the medical register and the Geiers lost their licenses to practise medicine when the malpractice came to light. (see: scienceblogs.com/insolence/2009/05/22/why-not-just-castrate-them-part-2) Lupron is still used to stop puberty in gender dysphoric children, and has extremely dangerous side effects including sterility and low bone density, hence the need for greater rigour in diagnosis and exhausting all safer treatment options before prescribing it.
In all medicine, the guiding principle is "first do no harm". The risk of any treatment must be weighed against the benefit it can bring, and this must be backed up by evidence - the more invasive or experimental the treatment, the more rigorous we must be in justifying its use.
This section also appears to contradict the "GIRES' conclusion" paragraph, "There is... no evidence that treatment targeting gender dysphoria, [sic] can overcome both gender dysphoria and autism". So, can medical transition alleviate some autistic difficulties, or can't it? Is there evidence to support this claim, or isn't there?
The suggestion that GD was mistaken for ASD also concerns us - if it's easy to mistake gender dysphoria for autism, that implies that autism could also be mistaken for gender dysphoria. It suggests that the diagnostic process as it currently stands is not fit for purpose.
I am encouraged by the conclusion "Clinicians working in the field need to be aware of this possibility. When in doubt, it may be necessary to obtain an opinion from a paediatrician who specialises in ASD", and would entirely agree.
Has the GIRES web-site been updated to reflect this conclusion? Currently, the 2016 report is still on the GIRES site ( www.gires.org.uk/wp-content/uploads/2016/04/GIRES-Young-People-Response-to-Service-Spec-1.pdf ) but I couldn't find anything contradicting or updating this anywhere else on the site. Could you send me the link?"
I suspect it's not actually anywhere else on the site, but I'll give her a chance to respond and possibly update it in the meantime...
