Epilepsy is a neurological disorder characterized by recurring seizures. Seizures are periods of abnormal electrical activity in the brain that can cause a person to lose consciousness, have hallucinations, and experience severe muscle spasms.
There are two main types of seizures that people with epilepsy may experience:
-
Focal seizures, where abnormal electrical activity is limited to a specific region of the brain.
-
Generalized seizures (also known as tonic-clonic or grand mal seizures), where abnormal electrical activity affects the whole brain.[1]
