What phase follows the tonic phase in a Grand Mal seizure?

During a Grand Mal seizure, also known as a tonic-clonic seizure, the tonic phase is characterized by muscle rigidity and a loss of consciousness. Following this phase, the clonic phase occurs, which involves rhythmic jerking movements of the body's muscles. This phase is marked by alternating contractions and relaxations, leading to observable shaking or convulsions.

The clonic activity follows the initial tonic phase as the brain’s electrical activity transitions from the sustained contraction to the rapid, repetitive muscle movements typical in the clonic phase. Understanding this sequence is crucial for recognizing the different stages of a seizure and providing appropriate care. Recognizing this progression also aids in understanding the dynamics of seizure activity and the typical presentation in a patient experiencing a Grand Mal seizure.
