In this article, we will take a detailed look at the 20 countries with the highest rates of epilepsy with insights into number of epilepsy cases by country and population. For a quick overview of 5 countries with high epilepsy rates, read our article 5 Countries with Highest Rate of Epilepsy.
Epilepsy is a common neurological disorder that affects people of all ages. Recurrent seizures episodes of abnormal electrical activity in the brain characterize it. The prevalence of epilepsy worldwide is estimated to be 70 million people. Each year, approximately 2.4 million new epilepsy cases arise globally, with 90% of cases being from underdeveloped and developing countries. This means that about 1 in 100 people will have epilepsy at some point.
In high-income countries, epilepsy is estimated to affect 49 people out of every 100,000 each year. This figure can be much higher in low and middle income countries, reaching 139 per 100,000. Approximately 60% to 90% of affected individuals remain untreated due to limited healthcare access and the stigma surrounding condition.
However, up to 70% of people can live seizure-free lives if epilepsy is properly diagnosed and treated. With the right treatment, most people with epilepsy can live normal, productive lives.
