Despite the demise of the original Dore programme, evidence continues to mount that the cerebellum plays a critical part in the dyslexia.
A new study, in the BMC Neuroscience journal, has found significant differences in the right cerebellum in dyslexics when compared to non-dyslexic controls. The study looked at 76 adults, evenly split between dyslexics and non-dyslexics. The subjects were extensively tested to confirm the diagnosis and then their brains were scanned.
Overall, there was no difference in the amount of grey matter in the dyslexic and non-dyslexic brains. However in specific areas, the right right cerebellum declive and the right lentiform nucleus, there were significant differences between the two groups.
Not only does this support the hypothesis of the cerebellum as a factor in dyslexia but it raises the potential for a diagnostic test based on physical differences. Being able to accurately diagnose dyslexia via a brain scan rather than relying on subjective and culture specific spelling / memory test would be a huge advance. Especially if the technique can work on very young children, allowing the dyslexia to be treated before it has a major educational impact.
