Interepisode phenomenology of bipolar disorder and schizophrenia are qualitatively different (Current Psychiatry, March 2006). Printing Drs. Lake and Hurwitz’ wrong-headed nosology disserves patients because impressionable residents and students reading about it might take it as truth and adopt it unexamined.
I also fear that the authors have been swayed by the idea that DSM-IV-TR is necessarily valid. DSM-IV ensures that all disorders are called by the same names but may or may not represent valid conceptions of mental life and its disorders.
I do agree in part with rejecting the notion of “schizoaffective disorder,” as the term is grossly overused. I think “schizoaffective” is often an easy shorthand for “bad mental illness” and is too frequently used without considering the psychopathologic phenomenology evident over the course of the patient’s life.
