[Impact in response control, attention and hyperactivity behavior on children with obstructive sleep apnea hypopnea syndrome by integrated visual and auditory continuous performance test].

Objective To study the impact in response control, attention and hyperactivity behavior on children with obstructive sleep apnea hypopnea syndrome （OSAHS） by the integrated visual and auditory continuous performance test （IVA-CPT）. Methods Fifty-one children aged between 5 and 12 years were diagnosed as OSAHS by polysomnography （PSG） , and received adenotonsilleetomy and adenoideetomy or only adenoidectomy. Then received IVA-CPT and PSG before surgery, 3 months after surgery and 6 months after surgery （named as first, second and third time point）. These children were divided into two groups according to the disease course （group A ： course of disease < 5 years; group B ： course of disease ≥ 5 years）. The SPSS 19. 0 was used for statistical analysis. Results By balanced test, there were no differences in gender, body mass index （BMI） and disease severity among the two groups before surgery （P > 0.05）. The numbers of children with abnormal psychological behavior at three time points were32（62.7%）, 25（49.0%） and 8（15.7%）. The abnormal rate did not show statistical difference between the first and second time point （X^2 = 1.49, P = 0.163）, but did show statistical difference between the second and third time point （X^2 = 12.95, P 0.05）. AHI and LaSO2 did not exist interation effect of disease course and time. Conclusions OSAHS obviously affect the children's response control, attention and hyperactivity behavior, but can recover gradually after adenotonsillectomy and adenoidectomy or only adenoidectomy. Therefore, Children with OSAHS should receive treatment as early as possible so as to reduce the influence on psychology.
