In a generalized tonic-clonic (grand mal) seizure, the person will usually emit a short cry and fall to the floor. Their muscles will stiffen (tonic phase) and then their extremities will jerk and twitch (clonic phase). Bladder control may be lost. Consciousness is regained slowly.
After a seizure, the person may feel fatigued, confusion, and disorientation. This may last from 5 minutes to several hours or even days. Rarely, this disorientation may last up to 2 weeks. The person may fall asleep or gradually become less confused until full consciousness is regained.
