@Testoceratops if they don’t have a medical alert bracelet, and you don’t know why they are having a seizure, please don’t wait five minutes to call for help.
My brother was a type one diabetic who would have seizures if his blood sugar got too low, at that point it’s way less than 50 and the only way to save him is to get glucose in him. The seizure will stop but then he will go into a coma if he doesn’t get glucose.
