What is the primary characteristic of a Grand Mal seizure?

A Grand Mal seizure, also known as a tonic-clonic seizure, is characterized primarily by a combination of stiffening and jerking of the body. During the tonic phase, the muscles stiffen, causing the person to fall to the ground and become unresponsive. This is followed by the clonic phase, characterized by rhythmic muscle contractions and jerking movements of the body, particularly the arms and legs.

Understanding the features of a Grand Mal seizure is essential for recognizing the severity of the condition, as this type of seizure can lead to loss of consciousness and significant physical danger, such as injury from falling. It differentiates itself clearly from other types of seizures that involve less severe symptoms, such as momentary lapses in awareness or involuntary muscle twitches. Recognizing the hallmark symptoms can aid in identifying appropriate medical interventions and providing support during such episodes.
