Neurological Disorders Afflict Millions

BETHESDA, Md., Jan. 30 -- Government investigators have tried to pull together a rough estimate of the scope of neurological diseases in America.

They made estimates of the incidence or prevalence of a dozen diseases or conditions seen commonly by neurologists, and they came up with millions of patients, even by the relatively narrow and arbitrary criteria the researchers selected.

For instance, nearly three million Americans are living after a stroke, more than two million have epilepsy, and more than 35 million live with migraine, reported Deborah Hirtz, M.D., of the National Institutes of Neurological Disorders and Stroke here, and colleagues at the CDC in Atlanta.

The investigators used the best available data on the incidence of some disorders and the prevalence of others, and extrapolated from other sources when reliable data about disease burden were not available, they wrote in the Jan. 30 issue of Neurology.
