Magic and Disabilities, Wizard Genetics

I haven't found (though didn't look too long or hard) for bloggy opinions on the shape of autism in the Potterverse. Would wizard therapists use leglimancy in addition to ABA therapy, enabling recoveries or effecting communication breakthroughs in ways we muggle parents can only dream of? Or ameliorating symptoms at least, for those kids who find themselves in horrible pain due to gut injuries, etc., and who act out because they can't tell anyone about their agony?

What would it be like to be a blind wizard child? Deaf? Have cerebral palsy? It seems as though magic abilities would offer fantastic empowerments to disabled kids, and those who work with them.

One item I did run across was a discussion on wizard genetics. And a link to a lightning rod blog, that of the Autism Diva.
