Three groups were formed by researchers, one was of children suffering with dyslexia and other two groups were of children free from the condition. Out of two control groups, one group was of children having age similar to that of dyslexia children and other was of younger children.
Researchers compared the reading abilities of dyslexia children group with that of reading abilities of younger age group. The study, which has been published in the Journal of Neuroscience, found less grey matter in dyslexic groups as compared to a control group matched by age.
Guinevere Eden, neuroscientist and Prof. at of paediatrics at Georgetown University Medical Centre (GUMC), said their approach seems best to control for both age as well as reading experience.
"If differences in brain anatomy in dyslexia were seen in comparison with both control groups, it would have suggested that reduced grey matter reflects underlying cause of reading deficit. But results observed are opposite", said Eden.
