It is another of those people who want to make a name for themselves by trying to question the existence of dyslexia and should simply be ignored! Yes there will be children who have difficulty learning to read for other reasons - but even once a dyslexic child has attained some degree of success in reading (if they actually manage to get the appropriate help) they continue to have spelling and writing issues! I actually couldn’t bear to continue to read it as I feel it once again just negates the real struggle of dyslexics!
About 3/4ths of the way through the article, the point becomes clear. Why should poor readers have to get a dyslexia diagnosis to get help? The point is a good one, but mired among the authors' obvious mistrust of commercially available dyslexia resources, few will see the argument. However to say dyslexia could be easily diagnosed and remediated in a classroom setting is disengenous.
