In addition to movement per se, movement disorders affect multiple mental processes and complex behavioral functions, and so must be taken into careful account when clinically managing a wide variety of behavioral problems. In Mental and Behavioral Dysfunction in Movement Disorders, internationally renowned researchers and clinicians review the many recent developments in the field, both to shed light on and to establish new standards for the study and treatment of the multiple cognitive, affective, and behavioral dysfunctions associated with movement disorders. These dysfunctions include depression, dementia, psychosis, sleep disorders arising from Parkinson's and Huntington's diseases, and Tourette syndrome, as well as multiple system atrophy, progressive supranuclear palsy, corticobasal degeneration, and many other related disorders. The authors describe these behavioral syndromes and their neurophysiological and neuropathological substratum, as well as their diagnostic criteria and therapeutic guidelines. For each syndrome, the cognitive deficits of attention, memory, language, praxis, and executive functions are spelled out in detail. Also discussed are the neuropsychiatry of movement disorders and the quality of life issues associated with Parkinson's disease.Exhaustive and cutting-edge, Mental and Behavioral Dysfunction in Movement Disorders illuminates the many complex mental and behavioral conditions associated with these disorders, and constitutes an essential guide for all physicians treating these problems or scientists studying these topics today.
