About Epilepsy
- 200,000 new cases of epilepsy are diagnosed each year.
- Incidence is highest under the age of 2 and over 65.
- 45,000 children under the age of 15 develop epilepsy each year.
- Males are slightly more likely to develop epilepsy than females.
- Incidence is greater in African American and socially disadvantaged populations.
- Trends show decreased incidence in children; increased incidence in the elderly.
- In 70 percent of new cases, no cause is apparent.
- 50 percent of people with new cases of epilepsy will have generalized onset seizures.
- Generalized seizures are more common in children under the age of 10; afterwards more than half of all new cases of epilepsy will have partial seizures.
- Prevalence of active epilepsy (history of the disorder plus a seizure or use of antiepileptic medicine within the past 5 years) is estimated as nearly 3 million in the United States.
- Prevalence tends to increase with age.
- 326,000 children through age 15 have epilepsy.
- More than 300,000 persons over the age of 65 have epilepsy.
- Higher among racial minorities than among Caucasians.
- Cumulative incidence (risk of developing epilepsy):
- By 20 years of age, one percent of the population can be expected to have developed epilepsy.
- By 75 years of age, three percent of the population can be expected to have been diagnosed with epilepsy, and ten percent will have experienced some type of seizure.
