My girlfriend's husband had Parkinson's.

One of the things I learned from her is that the medications can cause compulsiveness or impulsiveness. Her husband developed a strong desire to gamble which he never had before, and other inappropriate behaviors due to his meds.

Maybe let your doctor know if anything like this pops up before it gets you in trouble.
Example: Inappropriate sexual advances to women. You don't want to come across as a pervert, especially if it's not who you are, but the meds talking. Another could be excessive shopping.
