What is the Definition of a Tonic-Clonic Seizure?
Symptoms of a tonic-clonic seizure involve the whole body, and are characterized by uncontrolled muscle jerking and unconsciousness. This kind of seizure is commonly referred to as grand mal, and affects all age groups. Tonic-clonic seizures can be severe and, in extreme instances, fatal —thus, caregivers must follow safety precautions when tending to a patient during and after this type of seizure.
