Whether or not he was dyslexic, Einstein was a classic case of someone with learning disabilities.

Like what? Started learning violin at 6, calculus at 12, graduated from high school at 17 and got a teaching diploma at 21. Seems to have failed exactly one formal examination in his entire life, at 16. Didn't make much impression on anybody until his 20s, but that's hardly grounds for diagnosing a brain syndrome.
