Hi, funnylegs,

Crying out is listed as one of the ways people behave during a seizure:

Types of Seizures | Epilepsy | CDC

I've always understood that there's nothing much that anyone needs to do to help someone having a seizure except to let it pass. If it goes on for more than 5 minutes, that's an emergency to call 911 about. Otherwise you just make sure the person isn't in any danger.

Nobody knows much about just what is being experienced by a person having a seizure because there's never any memory of the seizure, but some people have seizures often and live perfectly normal lives otherwise.
