my mother in her 80s became psychotic, delusions, with hallucinations, paranoia, and memory problems and was accusing me of going to murder her (which is not true)
She was admitted to a hospital, put on antipsychotic meds, then returned home, but the problem started up again after a week. It was just awful, so I had to move out.
Now my father, he's in his 80s and he was in hospital for serious problem, but he was able to return home. But I worry about him because of his health problems and trying to survive in the community.
