Epilepsy is a brain disorder caused by recurring, brief changes in the brain's electrical system. These changes in brain activity can lead to a seizure(see Epilepsy Symptoms). It is not known exactly how ethosuximide works to treat absence seizures in people with epilepsy. It may work by affecting certain calcium channels in the brain.
