Abstract:
Objective: To investigate the cerebral cognitive function and intelligence in children with learning disorder (LD). Method:Thirty children with LD were examined with Wisconsin Card Sorting Test (WCST) and the Wechsler intelligence Scale for Children-Chinese Revised (WISC-CR). The results were then compared between LD and healthy control.Results:Compared with healthy control, the correct categories of WCST and correct responses in LD group were significantly lower (4.3?1.3/5.1?1.2). The persistent errors (38.6?10.7/23.9?8.4), total trials and total errors of WCST in LD were significantly higher than those in healthy control. In LD group, the full intelligence quotient (FIQ)(89.0?14.3/112.6?17.0) and the verbal intelligence quotient (VIQ) and performance intelligence quotient (PIQ) of WISC were all significantly lower than those in healthy control. So did scores of four factors of WISC, such as arithmetic, comprehension, and block design and object assembly. The incidence of abnormal intelligence structure in LD (80%) was significantly higher than that in healthy control (30%). The IQ in LD children was positively correlated with the correct categories and correct responses of WCST, and negatively with the total trials and the total errors and persistent errors of WCST.Conclusion:LD children suffered the frontal executive function deficits and cognitive dysfunction.
