Not a doctor or student, but I’m wondering what the purpose is of a short EEG. Sometimes in r/epilepsy, someone will say that they had a seizure, their neurologist had them do a 30 minute EEG which found no seizure activity, and then will just say it’s not epilepsy or will diagnose them with PNES. But the likelihood of catching a seizure in that short of an amount of time is so miniscule, why bother doing it in the first place?
