In a long-term study of schizophrenia patients released during the late 1950s and early 1960s from the back wards of Vermont State Hospital, Courtenay Harding reported that twenty years later 25% to 50% of the patients were completely off their medications, suffered no further signs and symptoms of schizophrenia, and were functioning well. She concluded that it was a “myth” that schizophrenia patients must be on the drugs all their lives, and the reality was that “it may be a small percentage who need medication indefinitely.”
