The book serves as an overview of concepts and methods rather than as an exhaustive treatise on all neuropsychiatric problems, and it is divided into three major sections. Part 1 (chapters 1–7) reviews the history and current status of neuropsychiatry. In this section, Arciniegas and Beresford introduce a neuropsychiatric approach to use for conceptualizing and understanding basic and complex cognition, emotion, personality, and psychological adaptation. Part 2, A Neuropsychiatric Approach to Evaluating the Patient, describes the fundamental tools that should be used to understand neuropsychiatric disorders, including the neuropsychiatric evaluation, mental status examination, electrophysiology, and neuroimaging techniques. Finally, part 3 (chapters 12–18) examines several neuropsychiatric disorders with the purpose of providing an explicit application of the relevant concepts and methods discussed in part 1. Selected topics relevant to clinical neuropsychiatry are highlighted, including delirium, dementia, obsessive-compulsive disorder, Parkinson’s disease, and traumatic brain injury, as well as diminished motivation, apathy, and alcoholism and other alcohol-related disorders. The ultimate goal is to permit generalizability and application of the approach to the clinical management and care of patients with other neuropsychiatric disorders.
