Abstract: Objective  To observe the clinical effect of cognitive perceptual function training on the intelligent development of children with brain injury.Methods  Ninetysix cases of children with brain injury syndrome were divided into control group and observation group， 48 cases in control group with routine comprehensive rehabilitation training， observation group of children on the basis of routine comprehensive rehabilitation treatment combined with early cognitive perception function training，and 3 months after treatment， separately Gesell psychological behavior were evaluated in two groups of children. Results  Two groups improved social adaptation， big action， language and individual social development quotient (P<0.05)， and there was no difference in fine motor development quotient (P>0.05). The improvement of intelligence in observation group after training was better than that of control group (P<0.05).There was significant difference in the social development quotient between edge intelligence group and mental retardation group(P<0.05).  Observation group showed  significant difference  in the intelligence level social adaptation development  as compared with  control group(P<0.05).Conclusion  Early cognitive perception function training can improve the mental development in children with brain injury syndrome， and  to promote the development of other functional areas， children with different intelligence have different levels of improvement.
