Impaired language comprehension has been consistently found in autism spectrum disorder (ASD). Development of language comprehension highly corresponds to joint attention and impulsivity. We used diffusion spectrum imaging to measure white matter integrity of the language comprehension network and the attention pathways in 60 ASD and 55 typically developing (TD) boys. ASD showed partially reduced white matter integrity in the targeted tracts as compared to TD. The tract covariance between the language comprehension network and the attention pathways showed different patterns in both groups which may shed light in the relationships of language and attention in ASD.
