Epilepsy is a disorder characterized by recurrent seizures. Seizures are caused by abnormal activity of nerve cells, called neurons, in the brain. In the United States, about 2 million people have epilepsy and as many as 150,000 more develop the condition each year. About a third of them are children. Epilepsy has many possible causes, such as an imbalance of nerve-signaling chemicals, called neurotransmitters, or abnormal nerve connections that form after an injury such as head trauma or stroke. Other types of epilepsy run in families and have been tied to specific genes.
