The last time I saw this story come up (if I recall correctly it was on 60 minutes a few years back), it was mentioned that antipsychotics worked to alleviating the symptoms; the real problem is that most of the patients experiencing these symptoms didn't _want_ to be told that it was mental, and would refuse to take antipsychotics as a potential solution.

How else could the doctors informing the patients of the real problem, and pointing them at a real solution to the problem?
