It's up to you whether you disclose it or not, considering you don't think you'll need any support for it, but I still would if God forbid it gets worse later and you need to make mitigating circumstances requests. Much easier, lower evidential standard when it's in relation to a worsening of a declared condition that is not the result of just not taking your medication, or you find yourself in need of support later, you're already known the accessibility team.
