Science essay in today’s New York Times adds evidence that diagnoses of Schizophrenia and Bipolar are more controversial than Multiple Personality

It is silly when articles about multiple personality begin by saying it is psychiatry’s most controversial diagnosis. Multiple personality has been known for thousands of years, and is controversial only with people who have never made the diagnosis.

Diagnoses of schizophrenia and bipolar disorder are less specific. For example, an unknown number of people who are given these diagnoses may actually have disorders of the immune system:

This is not to say that schizophrenia and bipolar disorder are invalid diagnoses or should not be treated. I have made these diagnoses many times and employed standard treatments.

But I have also diagnosed multiple personality, and I know it is a more specific condition.
