An understanding of seizures and epilepsy often begins with an appreciation of the brain's basic structure and function. The brain is the body's control center. It is responsible for our senses and memory, our vision and motor control, and a host of vital functions, with specific regions of the brain controlling particular functions.

A seizure disrupts normal brain activity and function. How a seizure affects an individual depends largely on which part and how much of the brain is involved. Thus, an individual's seizure type is directly linked to brain structure and function.

To see how this connection plays out in a child with epilepsy, first explore four key brain regions in the BRAIN ANATOMY section. Then, in the SEIZURE TYPES section, see and hear descriptions of three primary seizure types and how they relate to brain structure and function.
