Kanye  West is being slammed as “ignorant” and “distasteful” over a lyric on  his new album which uses Parkinson’s disease as a punch line … TMZ has  learned.

The song in question is called “On Sight” — which includes the  lyric, “A monster about to come alive again / Soon as I pull up and park the  Benz / We get this bitch shaking like Parkinson’s.”

Now, TMZ has learned  the American Parkinson Disease Association is upset about the  lyric — with the org.’s VP Kathryn Whitford telling us, “We find these lyrics  distasteful and the product of obvious ignorance.”

FYI — the APDA has  been around for over 50 years and it’s the largest organization in the country dedicated to helping those with Parkinson’s and furthering efforts to find a  cure.

So far, no response from Kanye’s camp.
