Essential to the management of patients suffering from neurological disorders is an understanding of the cognitive aspects of these conditions. This book begins with an outline of the various cognitive domains and how they can be tested, before covering in depth the cognitive deficits seen not only in prototypical neurodegenerative cognitive disorders (Alzheimer's disease, frontotemporal dementias, Huntington's disease, prionoses), but also in other common neurological disorders which may be complicated by cognitive impairment (stroke, multiple sclerosis, Parkinson's disease, brain tumours). This book is an essential reference text for all neurologists, not just those with an interest in cognitive disorders; and for general physicians and specialists who deal with any endocrine, metabolic, vascular, or infective disorders which may compromise cognitive function. Practitioners of professions allied to medicine which involve contact with cognitively impaired patients will also find this text useful.
