Researchers now report finding evidence of these differences in infants as young as six months. In a study conducted at Boston Children’s hospital, researchers used DTI (diffusion tensor) imaging to map the development of brain tracts in infants between the ages of six and seventeen months. They compared the brain images of a group of infants with a family history of dyslexia (FHD) with a matched group of similar infants with no such history of dyslexia. 

The researchers found significant differences in the development of white matter in the left hemisphere among the infants in the FHD group, similar to the structural differences seen among older dyslexic children and adults in other studies.   The researchers also found that the differences in left-brain white matter density could be correlated with development of expressive language skills .
