It is becoming increasingly clear that the clinically heterogenous presentation of Parkinson's "Disease reflects compromise of both dopaminergic and non-dopaminergic systems...A more complete understanding of Parkinson's Disease mandates an in-depth exploration of the many other compromised neural systems. The contributions edited by Drs. Halliday, Barker, and Rowe have succeeded remarkably---. But more significantly, each chapter provides a cogent and succinctdiscussion of the relevant basic as well as applied physiology for each compromised system, and can serve as an up-to-date primer of translational clinical neurophysiology for practicing as well asacademic Neurologists. This is an outstanding one-of-a-kind book, and a must read." - Stanley H. Appel MD, Peggy and Gary Edwards Distinguished Endowed Chair for the Treatment and Research of ALS, Chair, Dept of Neurology, Methodist Neurological Institute, Houston, TX"This interesting book...focuses upon a range of Parkinson's disease-related symptoms widely believed to have a non-dopaminergic basis. Such symptoms are almost exclusively "non-motor" in nature. It is thus highly topical, as our awareness of non-motor symptoms is increasing, together with the impact such symptoms have on the patient and their families. The book deals with non-motor symptoms in a systematic and in depth way, with a strong emphasis on the neuroanatomical and pathophysiological basis of the symptoms that will be welcomed by those wishing to acquire a more detailed understanding of the problems. The book... will be best appreciated by the reader with extant basic knowledge, aiming to move to a higher level of understanding." - David J Burn, Professor of Movement Disorders Neurology & Honorary Consultant Neurologist, Clinical Ageing Research Unit, Newcastle University Campus for Ageing and Vitality, Newcastle upon Tyne, UK
