I'm a student with learning disabilities, and regardless of their "issues" they should be working to help themselves because the "real world" won't. Plain and simple. I have found that the transition to post-secondary can be drastic, which could impact things but if they're disrupting your class, then that's not good.

If they're getting accomodations, then that means someone knows what exactly their issues are. They can't break confidentiality unless the student allows it, but talking to whomever signs off on disability accomodations is a very good idea.

Otherwise, to be honest, as a daughter of a teacher - I'd turf them (throw them out of your class). Bad attitudes are controllable to at least some degree.
