These are the most universally recognised seizures. They often begin with a sudden cry, the body becomes quite stiff (tonic) shortly followed by jerking of the muscles (clonic). The seizure usually lasts no more than 2 minutes and is followed by a period of confusion, agitation or sleep. Headaches and soreness are common afterwards. Previously called “Grand Mal”
