This is a scholarly textbook that provides comprehensive chapters on the clinical presentation and biological treatment of the major psychiatric disorders of late life: disordered behavior and psychoses, affective disorders (depression and mania), anxiety disorders, sleep disorders, and dementias. The treatment chapters provide a setting for describing the major classes of psychotropic medications: antipsychotics, antidepressants, mood stabilizers, benzodiazepines, and cognition-enhancing agents. These chapters follow a similar format, with a thorough review of the medication class, excellent tables summarizing the available clinical trials, clinical vignettes, and well-organized bibliographies with suggestions for further reading. The chapters describing the various clinical conditions are also well done. I found Reisberg and Kluger’s "Assessing the Progress of Dementia" to be a particularly useful synthesis of this group’s work.
