Epilepsy is a common neurological disease, characterized by recurring, unprovoked seizures. Unprovoked seizures are seen brief episodes of impaired behavior or awareness which are unrelated to other medical conditions, drug or alcohol use, or glucose levels. Those with an epileptic syndrome have forms of epilepsy where the type of seizure episodes (focal versus generalized) is known, with consistent EEG patterns. Epileptic seizures are generally caused by abnormal neurons altering the neural network, at local or global levels.
