What is epilepsy surgery?

Epilepsy surgery is any type of brain surgery where parts of the brain are removed, disconnected, destroyed, or stimulated to stop seizures. There are many different types of epilepsy surgeries. Which procedure is used depends upon the type of seizures presented, where they are localized in the brain, and the training and experience of the neurosurgeon.
Resections are surgeries that cut out part of the brain, while a disconnection is a procedure that disconnects part of the brain while leaving the rest of the brain intact. Other surgeries may destroy a small or large part of the brain with heat (laser), radiation, or by preventing blood flow.
