Visual Processing and Dyslexia

 

A brain imaging study of dyslexia shows that differences in the visual system do not cause the disorder, but instead are likely a consequence. The findings, published in the journal Neuron, address a long-standing debate about the role of visual symptoms observed in developmental dyslexia. The researchers point out that these findings could have important implications for practice. "Early identification and treatment of dyslexia should not revolve around these deficits in visual processing," says Olumide Olulade, PhD, the study's lead author and post-doctoral fellow at the Center for the Study of Learning at Georgetown University Medical Center. "While our study showed that there is a strong correlation between people's reading ability and brain activity in the visual system, it does not mean that training the visual system will result in better reading. We think it is the other way around."  http://medicalxpress.com/news/2013-06-brain-imaging-differences-visual-function.html
