Can simple partial seizures kill me? I go for an EEG on the 12th of August. What can I do until then?

It cannot really. Simple partial seizures are small seizures that are restricted to a small part of the brain and would be highly unlikely to cause death. You need to be on seizure medications to control them before and likely after EEG. The EEG does not cure you of the seizures. It is merely diagnostic and can miss your seizure if you are not having one at the time of your test.
