Abstract:
Objective:To investigate the relationship between median sagittal corpus callosum area and neural behavior in children with autism spectrum disorder (ASD).Methods:From January 2017 to December 2018, in Anhui Provincial Children's Hospital, 38 children with ASD were selected as the study group, and 35 matched children with normal development were selected as the control group.The autism behavior checklist (ABC) scale was used to evaluate the neurological behavior of children with ASD.All children were examined by cranial MRI.The total and partition area of the corpus callosum were measured at the median sagittal position, and the difference between the two groups was analyzed, as well as the relationship between the area of the corpus callosum and the abnormal neurological behavior of ASD.Results:The total and panition area size of corpus callosum in the study group were smaller than those in the control group[area 1: (182.63±30.99)mm 2 vs.(213.82±26.01)mm 2, area 2: (54.78±10.77)mm 2 vs.(63.75±12.53)mm 2, area 3: (45.16±6.52)mm 2 vs.(54.04±10.56)mm 2, area 4: (35.82±8.05)mm 2 vs.(49.93±14.47)mm 2, area 5 (127.63±26.50)mm 2 vs.(154.32±30.18)mm 2, total area: (445.31±64.91)mm 2 vs.(533.57±60.50)mm 2], and the differences were statistically significant ( t=-4.189, -2.982, -3.230, -4.363, -3.649, -5.543, all P<0.05). The differences between the two groups were mainly concentrated in the area of the knee, the area of the isthmus and the total area of the corpus callosum.The total area of corpus callosum was negatively correlated with 5 neurobehavioral dysfunction scores of ASD.The total area of corpus callosum was significantly correlated with communication disorder and language disorder ( r=-0.439, -0.544, all P<0.01). Conclusion:There are abnormalities in the development of the corpus callosum in children with ASD.The smaller the area of the corpus callosum, the more severe the clinical abnormal behavioral symptoms is.The measurement of corpus callosum area in children with ASD can provide support for diagnosis and disease assessment.
