Dear Franca--your father seems to me to be "his own worst enemy" in his refusal to take any PD meds. It must be a great worry to your mother and you to see him in such bad shape. While it is true that many who DO use meds have similar problems, and that the meds are not a CURE, they do provide a better quality of life for the PArkinsonian AND for the caregiver while they are effective. Then, too, every patient is different with this "designer disease" andyou are right that he doesn't know how he might do if he HAD taken them. (A single Sinemet is hardly a fair trial.) It seems that he is delusional at times, and as you say, paranoid--this is terrible for him and for your mother. If you've been on the list for a while, you have perhaps read about meds such as Clozaril, which can relieve the hallucinations,if one will use them. How can your mother survive having to get up with him 10 times a night? Her own health may be at risk, and if he is rational enough at times to realize this, it might motivate him to give the meds a fair trial--for HER sake, if not for his own. I wonder whether he would feel the same way about insulin if he had diabetes? It must be hard for him to see himself as needing meds after a lifetime of such superb health--perhaps it seems like a failure to him? You will certainly understand his thinking better than we can here- but there is the concern about your mother's survival too, and I suspect you may have some doubts yourself, or you wouldn't have written. It isn't clear how much of the time he is rational, and might be able to respond to a rational discussion of what the future holds for him and for her. I hope you don't take offense at what I have said, for I write out of concern for the whole family; all of you in a sense "have Parkinsons" and suffer the results of his refusal to help himself. Please stay in touch and let us know how things go in the future. Camilla Flintermann,CG for Peter,78/6+ Oxford,OH [log in to unmask]
