title: Urinary catecholamine metabolites during behavioral changes in a patient with manic-depressive cycles.
abstract: 3-Methoxy-4-hydroxyphenylglycol and normetanephrine were analyzed in daily urine specimens of a patient with manic-depressive cycles who was studied longitudinally. The quantities of these catecholamine metabolites excreted into urine were decreased during periods of depression as compared with periods of mania. Urinary excretion of 3-methoxy-4-hydroxyphenylglycol varied cyclically with a period length of approximately 20 days. Changes in this metabolite, and perhaps in normetanephrine, preceded the affective and behavioral shifts.
