Characteristics of cognitive function in children with attention-deficit/hyperactivity disorder with different levels of attention and control
Objective To analyze the characteristics of cognitive function in children with attention-deficit/hyperactivity disorder(ADHD)at different levels of attention and control,as well as their relationship with cognitive function.Methods A total of 104 children with ADHD who visited the Outpatient Department of Neurology and ADHD Clinic of the Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2022 to April 2023 were selected into this study to perform Wechwecht test,Integrated Visual and Auditory Continuous Performance Test(IVA-CPT),and cognitive function tests.According to the results of IVA-CPT,children with ADHD were divided into attention deficit type(ADHD-I),hyperactive and impulsive type(ADHD-HI)and combined type(ADHD-C).SPSS 23.0 statistical software package was used to compare the cognitive function characteristics of the three subtypes of ADHD children,and the correlation of cognitive function with symptom scores,attention and control was analyzed.Results There were significant differences in intelligence quotient(IQ),mathematical cognitive ability,numerical reasoning ability,sequential relationship and short-term memory span(flashback)among the three groups(P＜0.05).In pairwise comparisons,children with ADHD-HI showed superior IQ,mathematical cognitive abilities,numerical reasoning abilities,and sequential relationships compared to children with ADHD-C and ADHD-I(P＜0.05).The cognitive ability of ADHD children was positively correlated with IQ(r=0.332-0.399,P＜0.05).In the correlation analysis between cognitive function and IVA scores,sequential relationships and comparison performance were slightly positively correlated with IVA-CPT results in children with ADHD(r=0.300-0.337,P＜0.05).However,no significant correlation was found between cognitive function and SNAP-Ⅳsymptom scores(r＜0.3).Conclusions ADHD children with low attention level have poor cognitive functions.Attention is correlation with sequential relation and comparison size test scores.
