Growth and development of neuroepidemiology in India during the last four decades has been documented highlighting the historical milestones. The prevalence rates of the spectrum of neurological disorders from different regions of the country ranged from 967-4,070 with a mean of 2394 per 100000 population, providing a rough estimate of over 30 million people with neurological disorders (excluding neuroinfections and traumatic injuries). Prevalence and incidence rates of common disorders including epilepsy, stroke, Parkinson's disease and tremors determined through population-based surveys show considerable variation across different regions of the country. The need for a standardized screening questionnaire, uniform methodology for case ascertainment and diagnosis is an essential requiste for generating robust national data on neurological disorders. Higher rates of prevalence of neurological disorders in rural areas, 6-8 million people with epilepsy and high case fatality rates of stroke (27-42%) call for urgent strategies to establish outreach neurology services to cater to remote and rural areas, develop National Epilepsy Control Program and establish stroke units at different levels of health care pyramid.
