Schizophrenia-Associated Idiopathic Unconjugated Hyperbilirubinemia (Gilbert's Syndrome)

Abstract

The apparently higher frequency of Gilbert's syndrome in schizophrenic patients may reflect a relationship between hyperbilirubinemia and schizophrenic psychosis. Hypothetical explanations, such as a possible genetic disposition for Gilbert's syndrome, an increased vulnerability of red cell membranes, and the role of estrogens in schizophrenic patients, are discussed.
