Epilepsy is one of the most common neurological disorders.
An estimated 2.3 million Americans, at least 750,000 of them age 18 or younger, have epilepsy. Roughly 30 percent of epilepsy cases are attributed to severe head injury, brain tumor, poisoning, infection affecting the brain, or stroke. Some forms of epilepsy appear to have a genetic basis. But in most cases, the cause of the disorder is unknown. People who are able to bring their seizures under control with anti-seizure medications are able to live personally and professionally fulfilling lives.
