The Effects of 5-Hydroxytryptophan (A Serotonin Precursor) in Schizophrenic Patients

Abstract

Woolley has repeatedly drawn attention to the possible role of serotonin (5-hydroxytryptamine) in mental functioning (1, 2, 3, 4). In particular, this author has stressed the possibility that some forms of mental illness, such as schizophrenia, may be related to disorders in cerebral serotonin metabolism.
