And, I mean, if we're talking about neurodivergence more broadly and including people who generally "pass" as neurotypical, then that's a huge chunk of the population. Really, any time you talk to a patient, you should be assessing where they're at, in terms of general understanding and preferences, and should always tailor your approach to an individual.
It unfortunately is up to the individual to work with their practitioner to come up with an individualized plan of care. It really can't be any other way. Any attempt you make to come up with a universal standard of care for neurodiverse patients will necessarily exclude and likely harm people on other parts of the spectrum.
Over-generalizing these things sounds like a good idea up front, but it ends up causing more harm overall. We get stuck with narrow and rigid standards of care that just don't work for more than a small subset of people. This has been a real problem with autism in particular: until very recently the diagnosis and treatments were only concerned with young white boys. There's a very serious problem with women, adults, and all other groups being drastically under-diagnosed and left untreated. More generally, there are very few resources for autistic adults because of this. It's very slowly changing though
There’s too many particularities that can come up with individuals that are “non standard” for whatever reason. Any new physician for a particular patient could easily get up to speed on those particularities at the time it’s needed and not have to fumble through the friction it presents AND they don’t need any extra training to do so (probably?).
