My wife suffered a psychotic episode after 3 days on prednisone, stopped taking it, but had to be hospitalized for over a week, still having visual hallucinations that won't stop. She is now taking Aricept to lessen the symptoms, but gets depressed over not being able to stop seeing things and people that are not real. She has recovered to the point of knowing the hallucinations are not real, but can't make them stop.
