What is the difference between a grand mal seizure and tonic-clonic seizures?
Tonic-clonic seizures are a type of generalized seizure affecting the entire brain. Formerly known as grand mal seizures or gran mal seizures, these terms are now discouraged and rarely used in a clinical setting. Tonic-clonic seizures are the seizure type most commonly associated with epilepsy and seizures in general, though it is a misconception that they are the only type.
