Of all the PWP we've known, including people who have been on Sinemet for 20 years, we've never known anyone who evidenced the obsessive state you describe, or the paranoia. Hallucinations are not uncommon in the later years of PD, particularly in older patients, but many times those are fairly benign. Other times, of course, the hallucinations take a more frightening or threatening form. At Ron's age and after his shorter period of time on Sinemet, his symptoms are highly unusual. I'd be more likely to attribute them to underlying psychiatric problems. As others have said, it's clear that Ron shouldn't live alone or self-administer his meds. You're a good friend to Ron, and we wish you both the best as you look for solutions to his situation. Margie Swindler, cg for Dick, 52/15 [log in to unmask]
