Lucille and Geoffrey Leader are expert clinicians in the field of PD and neurological disorders. This book is essential for all patients and practitioners of PD. There is nothing available quite like it that deals with PD so practically and comprehensively, yet does not overwhelm. Thus it is perfect for the patient as well as the busy clinician. Not only does the book consider issues directly related to PD but also goes further and reveals areas practitioners may not have considered yet have a dramatic effect on the progress and wellbeing of the patient. It is truly invaluable.
