I am a new subscriber. My husband was diagnosed with PD about 6 yrs ago. He is now 71. I am the 24 hour caregiver. My husband has been under the care of a local neurologist since he was first diagnosed, and he has also been evaluated at Stanford .5 visits over several months, and since January, I have been taking him to Loma Linda to the movement disorder team. After the PD started, he slowly developed Dementia. This has become my biggest problem, since he walks all night, getting into things and generally making a mess and making lots of noise. Loma Linda put him on Hydergine, which has helped his dementia a great deal during the daytime. He seems to be a different person, at night, once he has slept even for a very short period. The doctors have tried a number of medications to make him sleep, but with no success. Some I can remember are Haldol, Zoloft, Risperdal. He jumps, yells, talks loudly, and is in general, worse than he is without the med. He takes Sinemet 25/100 3 times daily, Hydergine 15 mg daily, Theodur and Proventil tabs for asthma, B-6, B complex and a banana every night. I would be interested in any information about patients that have had the pallidotomy, and if they had previously had sleep disorder, did the surgery help the sleep problem?
