Who is more likely to have a problem communicating accurately and concisely? Someone with four years of college, four more of medical school, and three years of residency in a specialty, or someone with a disorder which has as a defining feature "difficulties with social communication"? So don't blame it on the doctor. Either improve your communication style, or bring an advocate. Of the two solutions, I think bringing an advocate is a faster and easier solution than a person with autism suddenly becoming a good communicator.
Well, happily, my own current doctor is ready and willing to make what one could call "reasonable accommodations" and reach out to communicate with me, knowing that communication in real time is something I was born unable to keep up with and never will be able to keep up with: the neuropsychological report says there is no hope of "improving" my communication beyond wherever it currently is; my processing speed is slow, and that's that.
If I were in a wheelchair, my wonderful doctor would undoubtedly come down the stairs to talk to me, rather than expect me to drag myself bodily up his staircase; or else maybe he'd have a lift I could use (actually his surgery is in a single-storey building, so this is just a metaphor, obviously).
The fact that I have a G.P. who can establish a conducive rapport and find a way for us to communicate effectively, and have previously had a psychotherapist who was also able to do those things, indicates it is possible for a professional with the will and right personality and the right attributes, such as sensitivity and empathy, to achieve this. But I have seen (or been seen by) countless professionals who either couldn't or wouldn't establish the necessary rapport, and couldn't or wouldn't go the extra mile to communicate: hence my sympathy for the plight Bellacat was describing.
I have heard some research on the B.B.C. indicating that psychiatrists typically spend more time talking than listening, during a consultation, and that chimed with my own experiences; this would be among the reasons it took them from 1995 until 2014 to diagnose my Asperger's, even after I attempted to suggest an A.S.D. diagnosis myself in 1998 (the two psychiatrists who saw me that year were not interested in listening).
Again, it would be wrong to condemn an entire profession, but the standard is not universally high; quality varies, within any profession.
I can't speak for Bellacat, but superadding the extra dimension of an "advocate" would only add to my confusion, not to mention my embarrassment. Still, it does sound a valuable option if available, and worth considering.
