ABOUT THIS BOOKThis is the first book-length treatment of the frequency and distribution of neurologic and sense disorders. It is based primarily on special tabulations of mortality data for 1959–1961 applied to the U.S. census of 1960. Information on incidence, prevalence, and survivorship is provided for each major disorder and a summary chapter considers the frequency and geographic distribution of neurologic disorders in terms of age, sex, color, and demographic characteristics.
