They don't say "Parkinson's Disease," because he wasn't diagnosed with it, he was diagnosed with "Parkinsons's Syndrome" which is a collection of symptoms that resemble the symptoms caused by the genetic defect known as Parkinson's Disease.
:::::::::::::::::::::::::::::::::::
A syndrome is a set of medical signs and symptoms that are correlated with each other and, often, with a particular disease or disorder.[1] The word derives from the Greek σύνδρομον, meaning "concurrence".[2] In some instances, a syndrome is so closely linked with a pathogenesis or cause that the words syndrome, disease, and disorder end up being used interchangeably for them.
If an underlying genetic cause is not suspected but known, a condition may be referred to as a genetic association (often just "association" in context). By definition, an association indicates that the collection of signs and symptoms occurs in combination more frequently than would be likely by chance alone.[3]

The case of Muhammad Ali is absolutely unique. I will provide a list of the most well known boxers who fought in his era at the highest level and took as much, if not much more punishment than Ali at the end of this rant.
If you examine as many boxers as you can, in video interviews available anywhere online, you will notice none of them display the same symptoms that Ali did, nor is their mental decline very similar. Ali was rendered completely silent at a relatively young age for a boxer. The mental decline of almost all of the fighters listed below can be observed through watching interviews of any particular fighter in ascending or descending order. Ali, due to his well known speed and athleticism, height and agility, did not take nearly as much punishment as other boxers in his era, such as "Smokin'" Joe Frazier who had all his wits and was able to speak until dying of liver cancer at age 67, and cases such as "Irish" Jerry Quarry, full blown dementia and an early death. But it's essential to point out that Ali never suffered any form of dementia. He simply lost his ability to speak.
He is seen at age 71 playing chess with former Undisputed Heavyweight Champion of the World "Iron" Mike Tyson here only a few years ago...https://www.youtube.com/watch?v=CJY8YQKFjfo
For a brief period in the late 1980's and early 90's Ali displayed muscle spasms and "shaking" but this only lasted a few years. He is seen numerous times for long periods of time in public completely normal looking, wearing sunglasses, and engaging people with handshakes and maybe a word or two. But he was never seen speaking for long periods of time, and even just a few words caused him much difficulty.
Muhammad Ali was a massive threat to the US Government and the Military Industrial Complex (MIT), as well as other governments across the globe. His anti-Vietnam stance and draft refusal have been publicized and taught at schools in all grades everywhere. His stance that certain white men who had elite power status on the planet were evil and needed to be eliminated was heard by everyone. Once he retired from boxing, he could have very easily run for President of the United States and won in a landslide victory. To say that it is more than likely that the US Government and MIT wanted him silenced is an understatement to a massive degree.
I submit he was very conveniently silenced, but not physically "assassinated." Assassination would have caused a massive uproar and chaos in the country and the world, and would have been extremely obvious. The way it was done was much more sophisticated and meticulous, and less obvious, and took until it was far too late to even speculate about.
