76 Follow-up of the Therapeutic Effects of Integrative Neuropsychological Training Model for Executive Functions Deficits in School-age Children Born Very Low Birth Weight with Normal Early Development-A Preliminary Report

Abstract

Objective:The preschool children born very low birth weight(VLBW) still have executive functions(EFs) deficits even with normal early development(Ni, Huang, & Guo, 2011). Consequently, early intervention might be more important than expected. This study aims to investigate the follow-up outcome of the therapeutic effects of integrative neuropsychological training model(INTM) focused on EFs for school-age VLBW children with EFs deficits.Participants and Methods:The VLBW children, recruited from the Regional Cohort Network for premature infants who were admitted to neonatal intensive care units, had normal scores in Bayley and Wechsler Intelligence systems before 6 years old. They also received follow-up neuropsychological assessment for EFs at 6 or 8-year-old. The deficits of EFs were defined from the result of Digit Span Subtest of WISC-IV, Knox's Cube Test(KCT), Tower of London(ToL), Wisconsin Card Sorting Test(WCST), and Comprehensive Nonverbal Attention Test Battery(CNAT). A total of 8 VLBW children with EFs deficits were recruited and received EFs training at 6 or 8-year-old. The INTM combined with Comprehensive Memory Training System(CMTS), Executive FUNction Training(EFT), and multi-ecological materials focused on enhancing the four aspects of EFs, including working memory, planning, cognitive flexibility, and inhibition ability. Then, they received follow-up neuropsychological assessment for EFs at 8 or 10-year-old.Results:The results showed that all children got benefits from 20 hours of INTM and most of the EF aspects remained improved at follow-up. A total of 8 VLBW children with an average of 3.4 aspects EFs deficits had an average of 1.4 aspects of EFs deficits left at the follow-up. More precisely, 5 of them had 1 aspects of EFs deficits and 3 of them had 2 aspects of EFs deficits.Conclusions:This study revealed that such a short-term INTM had long-term effects in enhancing the EFs of those VLBW children who had normal early development but later grew into EFs deficits at school-age. Besides, their EFs are still improving even after two years of intervention. Further study on more subjects with longer follow-up might help VLBW children to achieve better neuropsychological function.
