Grand Mal Seizure, Tonic-Clonic Seizure


A grand mal seizure, also known as a tonic-clonic seizure, is a type of seizure characterized by a sudden loss of consciousness, muscle stiffness (tonic phase), and rhythmic jerking movements (clonic phase). It is commonly associated with epilepsy and can result from various causes, including brain injury, infection, genetic factors, or metabolic imbalances.
