From your drug info in post #31:
"Elderly patients with dementia-related psychosis treated with antipsychotic
drugs are at an increased risk of death."
Well if it kills them, then they are no longer psychotic. Problem solved!
Dano, I would suggest having a good talk with a nutritionist and herbal medicine specialist, and try to gradually substitute good quality food and more natural solutions instead of prescription medicines. Since everyone is different physiologically, so is success at this. But worth a try.
