I hear this a lot from parents with children on the dyslexic spectrum. Some have had their children diagnosed and some haven't, but the bottom line remains the same: How do I help my child when the support he or she is receiving just isn't enough?
Children in this situation require two things: quality instruction and intensity. Images taken of the brain show a difference in the neural pathways of good readers versus poor ones. That means that the poor readers actually have to build new neural pathways. Sound hard? It is! The good news, however, is that it can be done. A Carnegie Mellon http://www.sciencedaily.com/releases/2009/12/091209121200.htm study proved that with an intensive remediation plan consisting of 100 hours of instruction, the transmission of brain signals had significantly increased. Even more encouraging, the changes lasted. Ten years later the brain scans of the poor readers were indistinguishable from those of the good readers.
