The basics

Adults with epilepsy

During 2021 and 2022, about 2.9 million U.S. adults 18 and older reported having active epilepsy.1

That is about 1% of all U.S. adults.

Active Epilepsy‎

Adults—an adult has active epilepsy if they were diagnosed with epilepsy or a seizure disorder and they are currently taking medicine to control it or had at least one seizure in the last 12 months (or both).


Children—a child has active epilepsy if their parent or guardian reports that a health care provider ever told them their child had epilepsy or seizure disorder, and their child currently has epilepsy or seizure disorder.2

Children with epilepsy

About 456,000 U.S. children 17 and younger have active epilepsy.2

U.S. data

2021 and 2022 data describing active epilepsy prevalence by age group, educational level, race and ethnicity, sex, current employment status, and insurance coverage are available. Also included are percentages of adults with active epilepsy by self-rated health status and disability status.

Data are also available describing epilepsy-related variables for adults with active epilepsy who have had at least one seizure over the past year, have taken anti-seizure medication, and have seen a neurologist or specialist in the last year.

Health care spending

Health care spending is higher for people with epilepsy or a seizure disorder, than for people without these conditions.

In 2019, the average annual health care spending for epilepsy and seizures alone was $24.5 billion in the United States.

  • Seizure costs were $19 billion.3
  • Epilepsy costs were $5.4 billion.3

Barriers to care

Adults with epilepsy have a harder time getting health care compared to adults without epilepsy.4 They were more likely to:

  • Be unable to afford any medicine or specialty care.
  • Be unable to afford dental or vision care.
  • Skip doses of medicine to save money.
  • Have trouble finding a health care provider or specialist.
  • Delay care because of transportation barriers.
  • Live in families having problems paying medical bills.
