Steven Spielberg says movies saved him from the stress and shame of dyslexia. (TE call home?) Henry Winkler (The Fonz) became master of the ad lib, since he couldn't make sense of the "Happy Days" scripts. Toby Cosgrove became a cardiac surgeon and is now CEO of Dr. Mike's Cleveland Clinic. These are just three of the more than 50 million North Americans who have dyslexia.

  But what exactly is dyslexia? Simply put, it's the inability to connect letters with sounds and put those sounds in the right order. Reading depends on accurate, consistent sound processing and ordering - even if, while you're reading, those sounds are heard only inside your brain!

  This new understanding of the sound-reading connection means some kids can ease their reading woes with auditory therapy. The therapy involves listening to sounds, syllables, words, and sentences (no reading), then trying to identify differences in pitch and accurately ID the meaning of a word or phrase by choosing a picture that represents it. This can rewire the brain so that sound is processed more accurately, and, yep, that improves reading.

  Early indications of dyslexia include: difficulty repeating a list of numbers or words, an inability to rhyme words or to enjoy hearing rhymes, confusing up/down and over/under, or misstating colors' names (saying "blue" for "green").

So, if you suspect your child has processing problems, get a diagnosis and begin auditory therapy BEFORE he or she starts trying to read. Remember, dyslexia needn't keep your child from enjoying school or success as an adult.

More research on the cause of dyslexia. 
Researchers at Northwestern University’s Auditory Neuroscience Laboratory investigated the underlying biological causes of dyslexia and found that a child’s reading ability is directly related to how efficiently the brain encodes sound. The study's results, published in the current issue of the Journal of Neuroscience, suggest that personal listening devices can improve reading ability by limiting the sounds that the brain encodes.

Dyslexia is a learning disability that impairs a person’s ability to either read or comprehend the written word. According to Nina Kraus, the study’s co-author and a professor of neurobiology and physiology at Northwestern University’s School of Communication, reading ability is often associated with auditory skills, including auditory memory and attention as well as rhyming ability.

The National Center for Learning Disabilities estimates that 15-20 percent of school-aged children suffer from some language-based learning disability. The most common is dyslexia.  
New research suggests that playing video games can help with with dyslexia.  I know that sounds strange, but in may be true.  
Playing action video games can boost reading skills in dyslexic children, a new study has found. In fact, 12 hours of video game play did more for reading skills than is normally achieved with a year of spontaneous reading development or demanding traditional reading treatments, according to the study published in the Cell Press journal Current Biology. - See more at:
This has proved to be a controversial study, but it is likely not far off where technology will take a more active role in helping those with dyslexia.  More to come.
