I think this is a case where Wikipedia is not a sufficient source (wonderful though the website is). While I respect you and your mother's experiences, I prefer published evidence over anecdotal. I'll refer you to the book rather than continue this thread: http://goo.gl/yjKGxj
You're confusing two things we're providing witness of:
My mother's anecdotal experience with the revolution of treatment of schizophrenia with anti-psychotics in the '50s, which merely dovetails with the Federal government also recognizing that this deserved a serious rethink of how we treat these formerly "hopeless" cases.
Our non-anecdotal watching of current events as this good impulse was totally botched over the next N decades.
E.g. I suppose it's an "anecdote" that I read not that long ago that the state is shutting down an institution for the mentally retarded a bit to the north of me, but that's not using the word in the way you mean.
Anyway, for us, "published 'evidence'" that per your statements contradicts the facts as we contemporaneously observed them, and for obvious political motives, is less than interesting. Especially when there are so many good, honest accounts of this out there.
