After a century of studying schizophrenia, the cause of the disorder remains unknown.

For bipolar in adults, I think there's pretty good agreement about what this looks like. For bipolar in children, there is some considerable debate about where are the boundaries. At the mild end, are these just kids who are active? Is this the class clown at the very severe - is this something other than a mood disorder?

Patients with DID or other dissociative disorders may be misdiagnosed as Schizophrenics on account of their auditory hallucinations, distrust, feelings of depersonalization, and on the MMPI (Kluft, 1987; Spiegel & Fink, 1979; Steingard & Frankel, 1985).

Undiagnosed DID patients received incorrect diagnoses of schizophrenia in 25% to 40% of cases in two large series (Putnam, 1989; Ross, 1989), while in one stores 12% and in the other 16% had received electroconvulsive therapy.

Many DID patients have been misdiagnosed as schizophrenics and treated with neuroleptics.

I was diagnosed with everything from schizophrenia to multiple personality disorder.
