Unless CD interferes with your work, I wouldn't tell the new supervisor. Let some time go by. Let the new supervisor find out how well you can perform. I have never found the biz world to be forgiving about anything.
It would be unethical for the existing supervisor to mention your condition to the new one.
I am starting a new job Monday and I plan to wait until I get to know everyone first. I will only tell them after I have shown them what a great employee I am. If I never feel like I should tell them then I won't tell them...
good luck making your decision. I agree some people are quick to judge and might automatically think something bad of you. Give yourself a chance to show them you are great first.
