epilepsy incidence

The incidence of epilepsy reflects the number of new cases diagnosed within a specific time frame and can vary significantly across different populations and countries.

In the United States, the Centers for Disease Control and Prevention (CDC) reports that approximately 2.9 million adults (aged 18 and older) reported having active epilepsy during the years 2021 and 2022. This accounts for about 1% of the adult population in the US. More detailed demographic data regarding these adults can be found on the CDC’s dedicated page for epilepsy statistics here.

Globally, it is estimated that around 5 million people are diagnosed with epilepsy each year, according to the World Health Organization (WHO). In high-income countries, the incidence is approximately 49 per 100,000 individuals. For more information on global statistics about epilepsy, visit the WHO page here.

A systematic review indicated that the annual cumulative incidence of epilepsy is about 67.77 per 100,000 persons, with an incidence rate measured at 61.44 per 100,000 person-years. This statistic illustrates the prevalence of new cases over time and highlights the ongoing burden of the condition within populations. For further insights into this systematic review, refer to the article found here.

Furthermore, a population-based analysis of the global burden of epilepsy has identified over 3 million new cases each year, emphasizing the widespread nature of this neurological disorder. This research can be accessed here.

Overall, while epilepsy is a common neurological disorder with significant implications for affected individuals, these statistics underscore the varying incidence rates and highlight the importance of awareness and research in managing and understanding this condition.
