When someone is diagnosed and treated long-term for schizophrenia, it would be nice if useful information like your post were passed on to children/grandchildren/ siblings.  Although I don't know who would be "in charge" of doing so.  Ideally, maybe the doctor or other professional would schedule a family meeting to answer everyone's questions.  My paternal grandfather had paranoid schizophrenia in the extreme and I saw him die in a straight-jacket in a locked room in a hospital psychiatric unit.  Yet I never once was aware that this increased my own risk of developing schizophrenia.  Even though I had hallucinations and delusions as a child along with deep depression as I got older, the diagnosis at age 37 really took me completely by surprise.  In fact, I didn't tie it in with a genetic element until after I had ECT and my mother off-handedly remarked that this grandfather had received ECT, too.  So, I guess my parents were somewhat negligent in conveniently setting aside the truth even when I was old enough to hear it.  Oh well.  It was a hell of a way to learn, though.  I would have been more alert to the prodromal symptoms and sought treatment earlier had I known.
