Epidemiology of epilepsy in India.

The article briefly reviews literature pertinent to the incidence, prevalence, prognosis, etiology, and treatment gap of epilepsy in India. Despite defective methodology, Indian studies have shown prevalence rates comparable with those from other countries. No incidence studies exist. Prognosis for those with epilepsy is worse in developing countries. The role of infection, especially neurocysticercosis, in the etiology of epilepsy has still to be fully worked out, as must the relative contributions of the other known etiological factors. Neuroimaging is needed to calculate attributable risk. Reasons for the treatment gap are discussed briefly, pointing out that in India, people seek alternative forms of treatment concurrently. The occurrence and effects of stigma are mentioned. The article ends with the author's opinion on how and where the epidemiology of epilepsy should proceed in the future.
