Yes. I'd just like to describe what it looks like when somebody has what you referred to as a grand mal seizure. We actually call them tonic-clonic seizures these days.
What happens is that the seizure is happening all over the unconscious person's brain. They become rigid. They become unconscious. They fall down. They begin to shake. Every muscle in their body is clenching and unclenching, clenching and unclenching. This can go on for a long time, but most seizures last less than five minutes. Of course, if it does go on longer, you call the ambulance.
That's basically what it looks like: the person's lying on the ground, totally unconscious, and they're unclenching and clenching their muscles and moving in a very spasmodic way. That would be the kind of seizure you're mentioning. It used to be called a grand mal seizure.
