Just checked this site ,again,after a long time. Have had 2 appointments with a new doctor. One I wanted no longer takes new patients, I think he is head of department.. new one is a movement disorder specialist. We were told my husband does not Parkinson’s. He has cerebellum ataxia. Stopped the sinemet and it made no difference.Dr saw him twice, one month apart. Tapered him off the sinemet and he had not taken it for 2 weeks before the appointment. Exam was unchanged from 1st appontment. will start PT again and get a Walker for bad times. He is very reluctant to use one. Have noticed that he is much worse in am , needs to eat frequently, I think he is having hypoglycemic periods, his walking is terrible when this happens. Will try keto diet n and see if it helps.
