Advances in the study and understanding of myasthenia gravis have led to the need for the publication of this important new edition. The goal of Myasthenia Gravis and Related Disorders, Second Edition is identical to the first – to provide the clinician and the scientist with a common resource for understanding this complex disorder. This new edition begins with discussions of neuromuscular junction structure and function and follows with updated chapters covering a wide range of topics, such as the acetylcholine receptor, clinical presentation, diagnostic evaluation, and treatment. Importantly, new supplemental chapters have been added; these discuss rigorous clinical assessments of patients for research trials and the epidemiology and genetics of myasthenia gravis. The discussion of the most challenging aspects of myasthenia gravis, its impact on patients’ psychological make-up, has been expanded as well. Myasthenia Gravis and Related Disorders, Second Edition retains the personal approach of the authors regarding treatment and is a valuable resource for meeting the many and varied needs of patients with myasthenia gravis.
