Dear Irv, Thanks for the info about Clozaril. My Mom is contacting the neurologist this week about the meds and will ask about this. My dad seemed to be doing much better when the amantadine (Symadine) was stopped, Buspar (buspirone) added, and the Sinemet dose was reduced. Unfortunately, the dementia is again pretty bad although the visual hallucinations have not returned. Perhaps he needs to be taken off the Sinemet completely. Thanks for your note. I hope your wife continues to do well. Roni Liebowitz
