`
`What Is Epilepsy?
`
`Epilepsy is a disorder of the brain that causes seizures. These seizures are not caused by a temporary underlying
`medical condition such as a high fever.
`
`Epilepsy can affect people in very different ways. This is because there are many causes and many different kinds of
`seizures. Some people may have multiple types of seizures or other medical conditions in addition to epilepsy. These factors
`play a major role in determining both the severity of the person’s condition and the impact it has on his or her life.
`
`
`The way a seizure looks depends on the type of seizure a person is experiencing. Some
`seizures can look like staring spells. Other seizures can cause a person to collapse, shake, and
`become unaware of what’s going on around them.
`
`Epilepsy can be caused by different conditions that affect a person’s brain. Many
`times the cause is unknown. Some causes include:
`
`Stroke (https://www.cdc.gov/stroke/index.htm).
`Brain tumor.
`Traumatic brain injury (https://www.cdc.gov/traumaticbraininjury/index.html) or head injury.
`Central nervous system infection.
`
`A person with epilepsy is not contagious and cannot give epilepsy to another person.

`
`Who Has Epilepsy?
`
`Active Epilepsy
`a
`Active Epilepsy.
`In 2015, 1.2% of the total US population had active epilepsy.
`
`1
`
`This is about 3.4 million people with epilepsy nationwide: 3 million adults and 470,000 children.
`
`1
`
`According to the latest estimates, about 0.6% of children aged 0-17 years have active epilepsy. Think of a school with
`1,2
`1,000 students—this means about 6 of them could have epilepsy.

`page.
`
`a Active epilepsy is defined as adults, participating in the 2015 NHIS, who reported a history of doctor-diagnosed epilepsy or
`seizure disorder and either were currently taking medication to control it, or had one or more seizures in the past year, or
`both.
