This might not be an accepted and standard test yet but I sure hope the potential for it being a diagnostic tool can be verified soon. A family friend's child got diagnosed at 5/6 years of age. They couldnt accept it at first and were in denial for a bit. This will be of great help if ever. Early diagnosis could mean a lot for both the family and child especially with the adjustments that would have to be made to ensure a better quality of care. Thanks for the post.
