I really don't know all that much. It's just that medicine and related topics interest me, and so when I read or hear something even remotely related, I remember it.

I saw a thing on a "Dr. Phil" show earlier this year about some people who thought their mom was psychotic because she was hearing voices and acting very strange. But she'd never shown psychotic symptoms at the normal time when schizophrenia and other psychotic illnesses come on--like between the ages of 18 and 24. Turns out, she was badly sleep deprived. They had two sleep doctors on the show who explained how sleep deprivation can mimic mental illness and psychosis.

Anyway, now you know. It was Dr. Phil, not me . . . .
