Seizures in children manifest in various forms, but they all share characteristics of sudden onset, sudden cessation, and periodic occurrence. Common types include grand mal seizures, absence seizures, and benign childhood epilepsy. During a grand mal seizure, the child suddenly loses consciousness, stops breathing, turns blue-purple, pupils dilate, limbs stiffen, hands clench into fists, followed by spasmodic convulsions, foaming at the mouth, with the episode generally lasting 1-5 minutes. Absence seizures in children present as sudden loss of consciousness, interruption of activity, staring or rolling of the eyes, but without falling down or convulsing, lasting 1-10 seconds, with consciousness quickly returning after the episode. Benign childhood epilepsy seizures often involve twitching of one side of the face, lips, or tongue, possibly accompanied by abnormal sensations in the area, inability to speak, drooling, generally with clear consciousness, with episodes occurring more frequently at night.
