Very interesting news about an ADHD eye movement test. Since this article is almost three years old, I wonder if there have been any more developments. Is this test used now to diagnose ADHD? If so, I sure hope it's not the only test used to determine if a child needs to be on medication for the disorder. It seems a bit too simple to be the only diagnostic tool. Perhaps a child just has trouble seeing and needs glasses, not ritalin.
