A Linguistic Approach to the Study of Dyslexia

Summary: Brain abnormalities in the reading network related to developmental dyslexia (DD) have been found to be consistent across languages, with greater reduction in grey matter volume and brain activation in certain regions of the brain for morpho-syllabic languages like Chinese compared to alphabetic languages, and vice versa. These differences are attributed to the specific language being learned while experiencing DD. In addition, compensatory brain regions as well as regions showing inconsistent alterations in brain structure and function were also observed.
