Abstract
A factor analysis was performed on data from 55 consecutive hospitalized psychiatric patients who showed 1 or more of 8 catatonic motor features. Two factors were extracted, accounting for 32% of the variance. Factor 1 (mutism, negativism and stupor) corresponded to the clinical family history or treatment response. Factor 2 (mutism, stereotypy, catalepsy and automatic obedience) corresponded to the classical description of catatonia, was associated with a research diagnosis of mania, and tended to predict a favorable treatment response. The 2 factors may reflect different forms of cerebral dysfunction which, in the case of factor 2, may provide clues as to the nature of the morbid process in mania.
