Objective To compare the difference of cognitive function between normal and abnormal IVA-CPT in ADHD children, and to explore the influence of cognitive function on symptoms of ADHD children. Methods A total of 189 ADHD children who visited the Department of Neurology and the ADHD clinic of Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2022 to June 2023 were selected. SNAP-IV scale, WechWecht intelligence test, IVA and cognitive function test were performed. According to the results of IVA, the ADHD children were divided into normal IVA group (TD) and abnormal IVA group (AB). SPSS23.0 software package was used to compare the differences of cognitive function between different phenotypes of ADHD children with IVA results. The correlation between cognitive function and IVA-CPT test results and symptom scores in ADHD children was analyzed. Results There was no significant difference in intelligence between TD group and AB group (P > 0.05). In the basic cognitive ability, the scores of basic reaction ability test, sequence relation test and comparison size test in TD group were better than those in AB group, and the results were statistically significant (Z=-2.165, -2.694, -3.297, P < 0.05). In the advanced cognitive function, the TD group had better short-term memory span (flashback) and Wisconsin Card Sorting Test (WCST) scores than the AB group (Z=-2.321, -2.583, P < 0.05). In the symptom assessment, the TD group had a significantly lower s
