I have taken a couple of the Parkinson's meds for another medical problem, and sometimes I had nights from hell - thought I was losing my mind. Also, the meds have a fine line between helping and hurting.
I don't know the answers to your questions, just understand a little bit of what the family is going thru. If his PD doesn't suffer too much from it, maybe they could talk to the doctor about trying him on a lower dose. It's a tough position to be in to need a medicine that has so many side effects.
We were told it can be the meds, the disease or a combination of both. I was able to find very little information about it. Good luck with your father. I'm sorry I don't know any places in Mexico, but wanted you to know I have experienced a little of what you are talking about.

I have tardive dyskinesia which is clinically similar to Parkinson's and I am under study for "tardive psychosis" as a criteria which is clinically similar to psychosis from Parkinson's. Zofran (Ondenastron), Clonidine and the natural remedy rhodiola (as supervised by a neurologist) have been of great help. Zofran is an FDA approved medication used off label for Parkinson's psychosis and the good thing about it is unlike conventional antipsychotics it will not cause tardive dyskinesia and thus will not worsen Parkinsons'. Its of some use for schizophrenia but can only be used as an adjunct. It can be used on Parkinson's psychosis. Look up the clinically valid studies linked to from the Wikipedia entry and bring them to your neurologist's attention although clearly a consult with a trained movement disorder specialist is neccessary.
