I forget, what's your position on these people:

Before the instruction, tests showed measurable differences in brain activity between children with dyslexia and those without the disorder, the Washington researchers say.

"We did MRI scans on 10 dyslexic and 11 non-dyslexic children," says co-researcher Elizabeth Aylward, a professor of radiology at the Center on Human Development and Disability. The children were in the fourth, fifth and sixth grades.

Aylward says there were differences in the activation of specific brain regions between the two groups of children when they were asked to perform a specific word task during the MRI.

After three weeks of specialized training, however, the dyslexic children showed brain activation patterns similar to the normal children during a second MRI. They also improved on reading tests, Aylward says.

"This shows that what the brain is looking for is to create interrelationships between sound and meaning," Berninger says.

"This also shows that you can get kids to improve their reading using the same brain pathways as normal readers," Aylward adds. "Even though dyslexia is a genetically based disorder, there is still enough plasticity in the brain that it can be jump-started."

Says Berninger: "I haven't cured them, but I have shown that they are teachable. These kids are ready to learn when they go back to school, but unfortunately the instructional practices aren't in place in the schools to support this jump-start."


Hi Liz,

I'm currious as to your thought's on whether dyslexia is a uni-dimensional disorder. That is, does one person with dyslexia have the same underlying cognitive system as another? Need the same treatment? etc. Clearly, clinicians need diagnostic categories (if for no other reason than to bill the insurance company). But having been in education for a while, and myself having some problems translating phonemes-to-graphemes, I really wonder whether we need to sub-divide dyslexia into mulipule disorders.

Do you know of any schools in the States for children who are 3 and 4 and found to have many symptoms of dyslexia. I believe the school would have to know about testing for those children and then how to remediate phonological awareness, visualize and auditory discrimination issues, dysgraphia, slow retrieval of words and so on.
Pre-schools for dyslexic children, info needed!
