The tremendous advances in understanding of the genetics and immunology of multiple sclerosis during the past 20 years have led to the development of experimental treatments and therapeutic approaches. The growing knowledge base and quickly expanding list of associated terms have become increasingly difficult to master. Dictionary of Multiple Sclerosis includes over 600 fully referenced terms and definitions from clinical neurology, genetics, molecular biology, biochemistry, immunology, pathology, pathogenesis, epidemiology, radiology, and clinical trial methodology. This is not a textbook but rather a desktop resource that provides convenient definitions to each term, supported by key references. With an ever-increasing amount of information available from a wide variety of sources, often presented in jargon that can be convoluted, confusing, and difficult to understand, this book is a welcome addition to the literature. It is an invaluable reference tool for clinicians and paraclinical personnel, as well as those personally affected by MS.
