No, I don't think you can cure autism. You can provide therapies that help autistics deal with their symptoms, but the underlying neurological anomaly is still there.

It is like the diabetic whose glucose levels may be in the normal range when he follows a strict diet, but his body is still incapable of functioning properly if he eats sugar. The condition isn't cured, just controlled.

I don't see cures. I see ways of alleviating symptoms.
