How epilepsy impacts people's lives

Epilepsy is the fourth most common neurological condition, and one in 26 people in the U.S. will develop epilepsy in his or her lifetime.1 Epilepsy manifests as unprovoked seizures, which are caused by abnormal firing of impulses from nerve cells in the brain.2 Partial-onset seizures, the most common type of seizure, are characterized by bursts of electrical activity that are initially focused in specific areas of the brain and may become more widespread, with symptoms varying according to the affected areas.3

The unpredictable nature of seizures may have a significant impact on those with epilepsy. Reducing the frequency of seizures may lessen the burden of epilepsy.4 With approximately one-third of people living with epilepsy still unable to control seizures, there continues to be a need for new therapies.4 Up to 40% of people living with epilepsy do not respond to the first or second monotherapy5, and approximately 36% fail to achieve adequate control of seizures despite the use of two or more antiepileptic medications.6
