A large number of neurological conditions result in abnormal movements of the body; these are often characterized by changes in coordination and altered speed of voluntary movement. Many obscure diseases, conditions and environmental insults can cause movement disorders but these are often overlooked. This volume expands and differentiates the many varied clinical presentations of movement disorders. Written by an international team of authors, including some of the most prominent clinicians in the field, disorders are defined and expanded in a clinically useful manner. Pathophysiological theories, genetic discoveries, new classifications, differential diagnoses and therapies are discussed extensively. Uncommon Causes of Movement Disorders provides a broad and comprehensive review of the field, concentrating on conditions infrequently seen but essential for practitioners to recognize in order to implement appropriate management. This is a key text for movement disorders specialists and general neurologists at all stages of their career. Features • Extensive use of tables and figures gives quick and easy access to key clinical, genetic and therapeutic information • Clear and logical format presents history reviews, clinical findings, causes and management strategies • Up-to-date discussion provided by practising clinicians enables learning from real experience Table of Contents Preface 1.
