Autism
spectrum disorders is a common brain developmental disorder that occurs in
one in 150 children. It is characterized by early onset of impaired social
reciprocity and communication difficulties, along with restricted interest
and stereotyped behavior. Several brain morphometry studies suggested that
cascade failure of neurodevelopment is the most likely the core deficit of
ASD. But whether aberrant WM development persisted into later childhood and
adolescence was a crucial issue to probe. The aim of the present study was to
examine WM microstructure using diffusion tensor imaging (DTI) and to
investigate its relations to age in adolescents with ASD.
