Neuroepidemiology covers the foundations of neuroepidemiological research and the epidemiology of disorders primarily affecting the nervous system, as well as those originating outside the nervous system. The etiology of many important central nervous system disorders remains elusive. Even with diseases where the key risk determinants have been identified, better prevention and therapy is needed to reduce high incidence and mortality. Although evolving technologies for studying disease provide opportunities for such, it is essential for researchers and clinicians to understand how best to apply such technology in the context of carefully characterized patient populations. By paying special attention to methodological approaches, this volume prepares new investigators from a variety of disciplines to conduct epidemiological studies in order to discern the etiologic factors and underlying mechanisms that influence the onset, progression, and recurrence of CNS disorders and diseases. The book also provides current information on methodological approaches for clinical neurologists seeking to expand their knowledge in research.
