The authors examined a sample of 111 consecutively admitted patients who
satisfied inclusion criteria for mania and further characterized them as
exhibiting none, one, or two or more of five clinical features often
believed to be associated with a diagnosis of schizophrenia: formal thought
disorder, first-rank symptoms, auditory hallucinations, persecutory
delusions, and catatonia. The presence and number of such symptoms were
unrelated to any of the major demographic, clinical, historical,
laboratory, or familial variables studied. The authors conclude that
schizophrenic symptoms do not play an important role in patients who
satisfy modern criteria for the diagnosis of mania.Abstract Teaser
