The authors evaluated 108 patients with schizophrenia, 50 patients with
affective disorder, and 74 age- and sex-matched control subjects by CAT
scan for evidence of global cerebellar atrophy. No difference was found
between control subjects and schizophrenic patients or between control
subjects and patients with affective disorder. This study does not confirm
previous reports linking cerebellar atrophy to schizophrenia.
