When brain cells are not working properly, a person's consciousness, movements or actions may be altered for a short time. These physical changes are called seizures. Epilepsy is sometimes called a seizure disorder. It affects people in all nations and of all races.
Epilepsy can begin at any time of life.
The remaining 41 percent of new cases start between the ages of 15 and 64. About one percent of the population, or an estimated 2.3 million people, have epilepsy. In more than 70 percent of all cases, no cause can be found. Epilepsy can be prevented by reducing risks of head injury or by developing new vaccines to prevent seizure-producing illnesses. For example, safety belts and air bags, motorcycle helmets, and safety seats for infants in automobiles protect against epilepsy as a result of auto accidents.
