Dyslexia Research and Resources

Mar 30 | Dyslexia Research and Resources

Elephant IllusionTrue dyslexia affects about 3 to 6 percent of the population. In its broadest sense, dyslexia is a learning disability that impairs a person's fluency or accuracy in being able to read, speak, and spell. It is not an intellectual disability but a learning disability. Symptoms of dyslexia are not due to poor vision or hearing but because of brain dysfunction. The eyes and ears are working properly but the lower centers of the brain scramble the images or sounds before they reach the higher centers of the brain. The problem is not what the dyslexic sees...but how their mind interprets the information. Look at the elephant and count his legs. Are there five...four? As you look at the image your brain jumps back and forth from "seeing" first four and then five legs. Imagine though that as you read this post your brain does the same thing; not with the drawing...but with the letters. Like an optical illusion...the dyslexic brain does not properly interpret the information it's given.

10 Years of Brain Imaging Research Shows The Brain Reads Sound By Sound A dyslexia research team at Yale University's Center for Learning and Attention lead by Dr. Sally Shaywitz has found a window on the brain through a new imaging technique called functional MRI. These medical scientists have identified parts of the brain used in reading. By observing the flow of oxygen-rich blood to working brain cells, they have found that people who know how to sound out words can rapidly process what they see. This information has shed new light on dyslexia and how to help dyslexics.

Dyslexia linked to muscle control Dyslexia could be caused by defects in the part of the brain that controls muscle co-ordination, Edinburgh scientists have discovered. Edinburgh University scientists have found the cerebellum, at the base of the brain, may influence how a person learns to interpret written language. They hope the findings will improve understanding and diagnosis of the condition.

Dyslexia v Design: Innovation Promises New Hope for Children with Dyslexia Reading and retaining information. That's the challenge faced by the one in five children who have some form of dyslexia. Overcoming that challenge could soon become easier for educators and children thanks to pioneering design research from the University of Cincinnati's internationally ranked College of Design, Architecture, Art, and Planning (DAAP).

Gene Associated With Language, Speech And Reading Disorders Identified ScienceDaily (Aug. 28, 2009) — A new candidate gene for Specific Language Impairment has been identified by a research team directed by Mabel Rice at the University of Kansas, in collaboration with Shelley Smith, University of Nebraska Medical Center, and Javier Gayán of Neocodex, Seville, Spain.

Handedness and Language-Related Disorders: Gene Discovery Supports Link ScienceDaily (Nov. 5, 2010) — Scientists at the Wellcome Trust Centre for Human Genetics, University of Oxford, have identified a genetic variant which influences whether a person with dyslexia is more skilled with either the left or right hand. The finding identifies a novel gene for handedness and provides the first genetic evidence to support a much speculated link between handedness and a language-related disorder.
