I wouldn't mention it either to be honest, nor would I have it mentioned in a reference. You have the right to a place at university in spite of any personal health condition, and rightly or wrongly it could influence their decision to interview. As could mentioning depression, chronic back pain, multiple sclerosis, HIV. Anything you can think of! Once you have been offered a place they legally cant rescind it, but stigma and discrimination unfortunately arent things of the past, and though it may not be active and conscious it could play a role in how they picture you as a candidate. Dont run the risk. Give yourself the best shot of being offered a place based on the things that matter!
EDIT: If you do go on to get a place you will have to declare any health concerns that could influence your studies, or practice as a doctor, to occupational health. Tell them then.
