My mother suffers schizoaffective disorder that caused her dementia. seems both feed each other. besides medicines, cognitive therapy would help her, how to improve her brain health? i think dementia prevents her from abandon her manic ideas from sd?

Dementia is the general term for cognitive dysfunction, and this encompasses numerous structural brain disorders, and toxic and inflammatory conditions, with the classic culprit Alzheimer's disease. Schizoaffective Psychosis is a psychiatric disorder and does NOT cause classical dementia. If this is confusing, a second opinion should be sought. Are her symptoms secondary to her medication?
