The cause of autism continues to be uncertain and conventional imaging is not helpful. These investigators used DTI to study the language-related white matter tracts in a subset of patients with autism and language impairments. Eighteen patients were compared with 25 controls and showed abnormal DTI parameters in the superior longitudinal fasciculus, particularly in its temporal portion and on the left side. Thus, the white matter subserving language in these patients was abnormal.
