Visual-motor Connectivity Disruption and Autism Spectrum Disorder

[Source:  Biological Psychiatry via Your Therapy Source]


Biological Psychiatry published research comparing resting state functional magnetic resonance imaging scans from 100 8- to 12-year-old children of which 50 had a diagnosis of autism spectrum disorder (ASD). The results were analyzed and functional connectivity was estimated between visual and motor systems. Brain-behavior relationships were evaluated by regressing functional connectivity measures with social deficit severity, imitation, and gesture performance scores.  The following results were found:

1.  increased intrinsic asynchrony between visual and motor systems in children with ASD
2.  children with more out-of-sync intrinsic visual-motor activity displayed more severe autistic traits
