Electrical brain activity leads to seizures
Epilepsy is a neurological disorder — not a disease — characterized by repeated seizures.
According to the Epilepsy Foundation of America, epilepsy affects people of all ages, races and ethnicities, and is the fourth most common neurological disorder in the U.S. after migraine, stroke, and Alzheimer's disease. It affects 65 million people worldwide.
One in 10 adults will have a seizure sometime during their life, but only about 1 to 3 percent of people will have epilepsy. Epileptic seizures are a result of abnormal electrical activity in part or all of the brain.
