Thoroughly updated and completely reorganized for a sharper clinical focus, the Fifth Edition of this world-renowned classic synthesizes the latest advances in basic neurobiology, biological psychiatry, and clinical neuropsychopharmacology. The book establishes a critical bridge connecting new discoveries in molecular and cellular biology, genetics, and neuroimaging with the etiology, diagnosis, and treatment of the full spectrum of neuropsychiatric disorders. Nine sections focus on specific groups of disorders--disorders of development; schizophrenia and related disorders; anxiety and stress disorders; affective disorders; Alzheimer's and other dementias; substance use disorders; impulsive and compulsive disorders; movement disorders and paroxysmal disorders; and chronobiology and sleep disorders. Each group of disorders is discussed in detail, including clinical course, genetics, neurobiology, neuroimaging, and current and emerging therapeutics. Four sections cover neurotransmitter and signal transduction, emerging methods in molecular biology and genetics, emerging imaging technologies and their psychiatric applications, and drug discovery and evaluation.
