Epilepsy is a tendency to have recurrent seizures.
Seizures occur when there is an imbalance in the electrical activity of the brain.
The abnormal electrical activity causes seizures. The seizures may occur one at a time, or they may occur one after another with little or no recovery in between. Any pattern of recurrent seizures can be called epilepsy. Epilepsy may or may not have an obvious cause. It can be hereditary.
