If you are planning to use your Class One for commercial purposes and it transpires at a later date that you have lied on the form (which it almost certainly will) you are guilty of fraud....... a criminal offence .
I had a similar problem many years ago with a family history of Epilepsy and had a the same conversation with the AME . Its better to get it sorted at the start before you go spending big bucks or you get into trouble with the CAA or the law.
Good Luck
