Print out that research article that said that up to a third of Parkinson's patients on these drugs developed compulsive behaviors. Fax it to his doctor along with a brief note detailing the behavior changes you've seen. Something along these lines:
Dear Dr. X You are currently treating my husband Mr Y for a pituitary growth. Lately he has had numerous behavioral changes including: getting a full sleeve tattoo, change in musical tastes, drinking, interest in swinging, and asking for a divorce.
It has been brought to my attention that dopamine agonist drugs can cause compulsive behavioral changes like pathological gambling and hypersexuality. I am concerned that my husband may be having side effects from his medication.
Please do not tell him that I conveyed this information to you - he will think that I am just trying to avoid a divorce. However I am sincerely concerned for his welfare, and felt you needed to know this information. I can be reached at
