Must the wife be informed about mild epilepsy after marriage, and is the failure to inform considered deceit or a sin?

Mild epilepsy that causes no harm is not considered an illness that necessitates annulment of marriage, nor does it affect the acceptance or rejection of a marriage proposal, unlike madness which causes harm. A mild illness that does not harm its possessor does not need to be disclosed to the wife, and not informing her about it is not considered deception.
