Ashleyk,
If I remember correctly, isn't your wife taking Nuplazid? Is it not helping the psychosis? If not, what does the doctor recommend? Everything I have read indicates it's a real balancing act-the more levodopa you take for movement, the worse the psychosis....but if you cut back on the levodopa, moving is a real problem but there are (usually) less hallucinations. It's a lousy choice to have to make
