My father had the problem of tremor in fingers and limbs and doctors say it is Parkinson s disease. He was given Syndopa and Syndopa plus apart from other medicines. He then consulted another Neurologist after 6 months and the Doctor advised him to take Syndopa plus, Parkin and Rasalect. Within a week, he had problems of Hallucinations and then he again consulted the doctor. Doctor reduced the dose of SYndopa and increased Parkin 2 mg for 3 times (1/2 tab each time). Later, he got very much difficulty in his mouth and it appears it is psychological. He is having very tough time from his mouth - most of the time, he keeps on washing his mouth and every week his case of mouth kept on changing. For a week, there are two sets of teeth, he has got cages in his teeth, he keeps on cleaning his mouth, he also says there is something like glycerine, sometimes he feels if there is no muscle and skin on his face etc. possibly this problem has emerged as Side effect of medicine. He has left all the medicines and not taking any at the moment since last one month. THough eventually doctor advised him to take Parkin. What should we do? Please suggest.
