That's interesting to me Formerlybrilliant and grizmom, because I've been saying ever since my mania, and my depression, that I've lost a lot of brain cells. I'm sure of this because the ability to do things, like spelling a word I know, or even coming up with one, or something simple just no longer can be counted on. The research that grizmom mentioned absolutely chills me. I've read much of it myself but hope that that won't be my experience. My age almost seems to be an advantage to me now. Maybe my meds will hold out as long as I do.
