My main thought is that since you're asking them to do something, it's better to keep the letter short. Maybe something like "Mr. Palmer had difficulties at his next appointment. These are related to his disability. For future visits, he needs" and then a bulleted list of things like "a nonverbal signal that he is having a problem. Soccer-style yellow and red cards work for him. That bulleted list of things you need can include reassurance that you can return and not be accused of wrongdoing, but for this purpose it doesn't matter why that happened.
"In order to return to your practice, I also need you to recognize what went wrong last time. I was doing my best to communicate, and your clinician appeared angry and accused me of being aggressive."
Put the explanations of why you need these things after saying what you need. It's more important that they make those changes, than that they understand why you need them.
I'd write this in the first person, using I/me/my, rather than the third-person "Mr. Palmer," because if the letter says "Mr. Palmer" repeatedly, they will probably think they're hearing from a caregiver/personal assistant, rather than the patient.
It's well known that, Unfortunately, many people will stop reading partway through a letter, email message, or newspaper story. You can't say everything you want to tell them in one paragraph, so try to write a letter that won't be misleading if they only read the first paragraph or two.
I would also drop the word "genius"--some people react badly to someone claiming to be a genius, whether or not it's true. Something like "intelligent patients who sometimes suffer from cognitive impairments, which can trigger a speech impediment" is also true, and more likely to get the results you need.
