"I know that this post, given that it contradicts the conventional wisdom that schizophrenia patients need to be on antipsychotics all their lives, will seem "outlandish" to some readers. But I think there is a consistent evidence trail here, and that it does lead to the conclusion that a difference in medication usage [they used less] in the WHO studies was a primary reason that patients in the developing countries fared better. And if so, that has profound implications for a "best use" model of care today."
