Indications of dyslexia found in infant brains

Wisconsin Reading Coalition:

A study by Nadine Gaab et al. from Boston Children’s Hospital’s Laboratory of Cognitive Neuroscience has detected alterations in the arcuate fasciculus in infants whose family history suggests risk for dyslexia. The arcuate fasciculus is a “bundle of fibers that connect the posterior cortex, which is involved in mapping sounds and word/letter recognition, with the frontal cortex, which integrates and comprehends this information.”

This follows a 2012 study in Gaab’s lab where MRI’s showed left hemisphere differences in brains of pre-reader kindergartners with a familial history of dyslexia.

Implications for early intervention are discussed.
