DRG Epidemiology’s coverage of epilepsy comprises epidemiological estimates of key patient populations in 45 countries. We report both the incidence and the prevalence of epilepsy for each country, as well as annualized case counts projected to the national population.

Most patient populations are forecast over a period of 20 years for the major mature pharmaceutical markets and 10 years for the other countries covered.

DRG Epidemiology’s epilepsy forecast will answer the following questions:

  • Of all people with epilepsy, how many in the countries have been formally diagnosed?
  • Of all people diagnosed with epilepsy, how many in each country across the major mature pharmaceutical markets are drug-treated?
  • How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of epilepsy over the forecast period?

All forecast data are available on the DRG Insights Platform in tabular format, with options to download to MS Excel. All populations are accompanied by a comprehensive description of the methods and data sources used, with hyperlinks to external sources. A summary evidence table generated as part of our systematic review of the epidemiological literature is provided for full transparency into research and methods.

In addition to the total number of cases for each forecast year, DRG Epidemiology provides at least ten years of forecast data for the following epilepsy subpopulations:

  • Total prevalent cases by level of seizures.

Note: Coverage may vary by country.
