Objective: This review article outlines the thinking and evidence behind our hypothesis that the problems suffered by dyslexic people may be attributable to some cerebellar deficits. Method: Firstly, we provide an overview of recent evidences that propose a central role for the cerebellum in cognitive skills in particular those scaffolded by spoken language in addition to its well-recognized role in motor skills. Secondly, some evidences from Sheffield Laboratory outlined that cerebellar function is abnormal in dyslexia condition. Results and Conclusion: Two specific lines of evidence are considered: behavioral and converging evidence from neuroimaging which demonstrate significant differences between the dyslexic and control groups. The same battery of behavioral tests was applied to a group of children who are non-discrepant poor readers. Finally, an ontogenetic casual chain was provided for the development of dyslexia in terms of cerebellar deficits from birth |
