Of course they "CHECK". It's part of your Federal Medical RECORD. The AME will not issue, but will defer the application. I too picked up the tone of "I would like to maybe leave it off". But that is not an option. I would remind you of a motion picture director named Roman Polanski. Google him. He's always fighting extradition. The Feds never forget.
Now, if you had epileptic seizures and have had no medication and have had four years without another event, you will need:
(1) Current evaluative visit with a board certified neurologist. He has to verify the history, agree and have no findings on a good exam.
(2) Current EEG (awake/asleep)
(3) Current Brain MRI.
Nine years after the event, if all are well, you can be issued BY THE AGENCY.
If, you had but one seizure, then you may not need 2 and 3. But it is your burden to prove lifelong (without observational break) that you have had one and only one- and you would not remember then, right? But you certainly will need #1 and the AME is NOT permitted to issue you. You get deferred.
