Epidemiology of Cerebellar Disorders

Abstract

This chapter explains briefly the epidemiology of several cerebellar disorders, many of which are considered rare, and various risk factors associated with their development. For many cerebellar disorders, prevalence and incidence rates are unknown, or the values have been underestimated; this is true both at the global and regional levels. Scant epidemiological information can be attributed to lack of healthcare systems in various parts of the world, inaccurate classification of disorders in published studies, broad inclusion criteria, or simply rarity of the particular disorder. Information about the prevalence, incidence, or number of cases is important for planning and provision of services to address the needs of affected individuals. Epidemiological studies are also necessary to identify factors that contribute to the development of the disorder, which can be used to prevent or reduce the risk of developing the conditions at the population level.
