America makes students with additional needs very welcome, and strong laws (rather stronger than in the UK) ensure they are not discriminated against.
If you have any type of disability or Special Educational Needs, make sure you tell the university from the start and confirm that they can accommodate you.
While most US universities are very adept at catering for disabled students and can normally provide an array of services, there may be additional costs - contact the university’s student services division for further information. As you will have to provide evidence of your disability, and the requirements differ from the UK, it is wise to start asking two years before you plan to enrol.
