This unique text offers practitioners both a review of the basic concepts of epidemiology, statistics, and clinical trials and a discussion of the epidemiologic aspects of many neurological diseases. Much of the information contained in Principles of Neuroepidemiology, such as cost-effectiveness analyses, has been difficult for busy practitioners to find in the past. By reading this book, physicians will acquire the skills they need to critically evaluate randomized trials that have affected the clinical practice of neurology.
