From what I can tell about the law school admissions process, the top two considerations that schools will look at is your GPA and your LSAT score. If you have killer scores, your odds are that much better.
Having said that, it doesn't necessarily mean you will be shut out because of poor scores, either. Which where the Personal Statement comes into play.
Regarding your disability, because it sounds as though your disablity is an on-going issue and also because you seem to have overcome it as a challenge versus an obstacle, I would bring it up as a point in the Personal Statement and accentuate the positive (assuming the application asks for factors as to why you would succeed at law school). In other words, put a positive spin on it to show the admissions committees that even with your disability you will be a successful student and future attorney.
As a matter of fact, your disability could be your PS theme, if done tactfully.
Hope this helps. Godspeed.
