I Have Or Know Someone With Parkinson's

My uncle has had it for a while, but only recently has it started to affect him cognitively. Just recently he was sent to the hospital because he was trying to escape the group home he just moved into; he was pulling fire alarms, going into people's rooms and flicking lights, etc. It's hard to see someone that you care about slowly lose their mind, as it were. I just hope that his new medication can help him calm down a bit.
