One of my friends who has PD, and has had two DBS, has a problem speaking. Both the ability and the volume have been affected. He was told it was because they passed thru the speech center of the brain while performing his DBS. The docs are considering botox injections on the vocal chords to help him.

My husband with PD has more trouble because he mumbles, perhaps more from never being able to stand up straight, and his voice goes straight down to the floor. My favorite word now is, "What?".

It's frustrating, I know. As our friend says, "Can't walk. Can't talk. Can't pee. Can't see. What next?".

Gotta keep laughing!
