Cerebellar morphology in chronic schizophrenic patients: a controlled computed tomography study.

Simple, objective, linear, and density measures were used to evaluate by computed tomography (CT) the cerebellum-fourth ventricular region of 23 chronic schizophrenic patients and 23 normal controls. Our data suggest that a subgroup of chronic schizophrenic patients have cerebellar atrophy associated with a strong but nonsignificant trend toward increased cerebellar density. The implications of these findings are discussed in view of previous CT and neuropathological studies.
