About 3.4 million Americans have a seizure disorder, also known as epilepsy, according to the Centers for Disease Control and Prevention (CDC). This number includes both adults and children, as the disorder can affect people very early in life.

Even if you have firsthand experience with epilepsy, you may still have questions about seizures, how the condition is diagnosed, and the ways it can be treated. Here are insights from Lee Dresser, MD, a neurologist in Wilmington, Delaware, about epilepsy.
