Abstract

Objective To investigate the cognitive function differences of predominantly inattentive subtype (PI) and combined subtype (CT) of attention deficit hyperactivity disorders (ADHD) patients,and provide references for clinical intervention for ADHD. Methods 171 children with ADHD were diagnosed and classified into three subtypes:PI,HI and CT according to DSM-IV criteria for ADHD.The Chinese Wechsler Intelligence Scale for Children (C-WISC)、Wisconsin Card Sorting Test (WCST),Continue Performance Test (CPT) and Number Cancellation Test (NCT) for Children were conducted to assess children's cognitive function.Results Compared to Patients with PI subtype,patients with CT subtype had higher scores both in arithmetic and full intelligence quotient subscales of the Chinese wechsler intelligence scale for children and in click number,error number and T score of error number of the continuous performance test(P all＜0.05).There were no statistically significant differences in WCST and NCT between CT and PI subtype. Conclusion Patients with CT subtype has higher general intelligence level and more impairment in response inhibition than those with PI subtype.
