Voxel-based morphometry studies have reported reduced gray matter volume in
temporal areas (fusiform gyrus) and cerebellum in children with developmental
dyslexia compared to healthy controls. These areas with less gray matter volume have
been linked to reading skills impairments, as these areas are related to reading
automaticity and word recognition. However, most of the patients in these studies
were speakers of languages with a deep orthography. The current study used 25
Spanish children (age range 9-14 years; mean age= 12.05 years; 12 healthy controls
and 13 dyslexic children).VBM was employed to determine the differences between
the dyslexic and healthy control groups, and the children performed different
phonological tasks to determine their scores on reading skills. Voxel-based
morphometry revealed significantly reduced gray matter volume in the fusiform gyrus
(left) and cerebellum in dyslexic children compared to the healthy control group. In
addition, when we correlated the scores on the phonological task with the gray matter
volume, the dyslexic children mainly showed less gray matter volume in the fusiform
gyrus on word reading time and pseudoword reading time tasks, and less GMV in the
thalamus on the verbal fluency (FAS-F) task. Results are consistent with the idea that
reading problems in languages with a shallow orthography are related to dysfunctions
in the fusiform area.
