Abstract: ObjectiveTo explore the state of intelligence and adaptive behavior of children with cerebral palsy and the correlation between them.Methods169 children with cerebral palsy were evaluated with Wechsler Intelligence Scale for Children (Chinese version) and the Infants-Junior Middle School Students' Social-Life Abilities Scale for the intelligence and the adaptive behavior.ResultsThe average scores of verbal intelligence quotient (VIQ), performance intelligence quotient (PIQ) and full intelligence quotient(FIQ) of the patients were lower than the normal children and the average scores of PIQ and FIQ were less than 70; the PIQ deficiency was significant more than the VIQ deficiency(P<0.001). 93 cases had mental deficiency, including 43(46.23%) for mild, 36(38.71%) for moderate, 13(13.98%) for severe, 1(1.08%) for extreme severe. There were 113(66.86%) for the deficiency of full social-life abilities, 104(61.54%) for Self-Help, 147(86.98%) for Locomotion, 133 (78.70%) for Occupation, 73 (43.20%) for Communication, 115(68.05%) for Socialization, 90 (53.25%) Self-Direction. The damage of Locomotion was the most serious, while the damage of Communication was the least serious. The outcomes of Wechsler Intelligence Scale was significantly correlated with the Infants-Junior Middle School Students' Social-Life Abilities Scale(P<0.001).ConclusionThe cerebral palsy causes not only intelligent damage, but also intelligence deficiency in most patients and the major level of the intelligent deficiency is mild to moderate. The damage of the performance intelligence has more influence on the full scale intelligence in the children with cerebral palsy. Most of the children with cerebral palsy have inconsistent deficiency of different aspects of the adaptive behavior.
