They probably didn't exist 9 years ago ZNXY.
No, I'm not a neurologist, but do have to differentiate these things sometime.
"Seizure" is a bit of a word that's sometimes banded around, and isn't always that clearly defined.The word itself is very subjective, even amongst us who have some training.
Anyone actually, with the right stimulus, is capable of having a "seizure."
The first seizure clinic, is designed to sort out the wheat from the chaff.
Usually, it's a single, transient event, sometimes related to fever, stress, tiredness, alcohol, drugs etc. (common)
Obviously, we have to make sure it's nothing more serious, such as a brain tumour or epilepsy. (not as common)
Reassuringly, you've had a single event 9 years ago, which doesn't seem to have recurred.
I suspect the next stage forward is to obtain your notes, and if required, get a specialist report. Have you spoke to to the RAF medical people yet, I suspect you'll have nothing to worry about.
