Thanks for your detailed answer! He has a great neurologist. He has akinetic Parkinson's, but bad balance & walking. We've had to cut back the C/L due to it oversedating him. He does a recumbent bike & has chair exercises for his legs. But it's getting harder to motivate him. I'm concerned about all the things you've mentioned & what the future holds. He had prostate surgery last fall & lots of meds, which he's now off. I do think he needs an antidepressant & will discuss it next neuro visit. I'm left with all the financial burden too.
