Whole lotta shaking: As jerry lee lewis says. Grand mal seizures are the kind of seizure that most people think of: people pass out, and their muscles contract violently. It usually lasts less than 5 minutes. Sometimes people have only 1 seizure & never have it again. Sometimes people have more than 1 seizure & need to take medicine to prevent them.

Electric chaos: The brain functions by electrical circuit communication. These circuits are usually very well regulated and modulated. If something causes them to go into chaos, an electrical storm may occur. When this electrical storm affects the regions of the brain that control the muscles, tonic and then clonic spasms of the muscles will develop. The storm then subsides and the body wants to sleep.
