Just my opinion, but this might be a sign that the medication is working. From your earlier post she seems to had gone catatonic, but now she had regained her motion. Tell the doctor about the temper part, because adjusting the medicine can help. Keep an eye on any patterns to her symptoms. Is it erratic? Cyclical?

As for long term care, sigh.... I have a brother with neurological problem that affects his mental abilities, and to be honest, I don't think the illness itself is the biggest problem, instead it is his behavior, and I think it is from how my parents treat him since childhood. It's too late now to reverse 20+ years of conditioning now, and I don't want to think how I will have to take care of him once my parents pass away.
