Six biological variables-platelet monoamine oxidase activity, urine phenylethylamine concentration, brain norepinephrine concentration, abnormalities on computerized tomog-raphy, lateralization asymmetries, and the presence or absence of tardive dyskinesia-are used to discriminate possible biological groups of schizophrenic patients. All variables successfully subclassify patients, some into divisions consistent with phenomological, psy-chosocial, or biochemical descriptions or hypotheses of schizophrenia. None of the measures, however, has sufficiently stood the test of time to be of clinical utility.
