He is also taking 25 mg of Tasmar everyday (since the last 2-3 weeks). My mother tells me that he is experiencing a lot of hallucinations at times due to this (mostly in the afternoons). His neuro thinks that he might try Olanzapine for the hallucinations. I just typed in the name in Alta Vista and its thrown up a huge list that I am yet to real in details. But skimming across somethings does make me think that this is what Mom was talking about- she told me over the phone and I wrote it down. >> I don't know about "olanzapine" for mental; disturbances. However, Clozapine is useful in PWPs. It returns the mindset of those with medicine induced mental dysfunction (mostly paranoid or inappropriate manic thinking) to something less antisocial. It almost seems good for what ails PWPs in the mental department. However, I do not know if it is prescribed for hallucinations and it requires a lot of blood testing to use. Regards, WHH
