Queener, I agree with Susie. She needs to see a specialist, a neurologist. I have not had any episodes like this but from what I have read, this is not something to be ignored. Of course, they would want to check for any kind of medication or drugs in her system as a matter of course. In addition to an EEG, there might be other tests as well.
