New findings have surfaced on the role of dopamine in the treatment of schizophrenia. This volume presents a review of those findings, first explaining the etiology of the disease and then profiling the action of antipsychotic drugs. The author presents all aspects of the pathophysiology and treatment of schizophrenia, including the imaging of dopamine systems in the brain. The text identifies genetic polymorphisms that affect dopaminergic neurotransmission and their possible impact on familial forms of schizophrenia. It also explores the neurophysiological and neurochemical studies of dopaminergic function.
