Abstract

In a prospective longitudinal study, the trajectory of verbal and visual-spatial working memory (WM) development was examined 2-, 6-, 12-, and 24-months following complicated-mild to severe pediatric traumatic brain injury (TBI; n = 55) relative to an orthopedic injury comparison group (n = 47). Individual growth curve modeling revealed an interaction of age, severity, and time for verbal, but not visual-spatial WM. The youngest children with severe TBI had the lowest scores and slowest verbal WM growth. WM outcome is best understood in light of age at injury and TBI severity. Findings support the early vulnerability hypothesis and highlight the need for long-term follow-up.

摘要

在一项前瞻性纵向研究中,相对于骨科损伤对照组(n = 47),在小儿复杂轻度至重度创伤性脑损伤(TBI;n = 55)后2个月、6个月、12个月和24个月,对言语和视觉空间工作记忆(WM)的发展轨迹进行了检查。个体生长曲线模型显示,言语WM存在年龄、严重程度和时间的交互作用,但视觉空间WM不存在。患有严重TBI的最年幼儿童得分最低,言语WM增长最慢。根据受伤时的年龄和TBI严重程度,能最好地理解WM结果。研究结果支持早期易损性假说,并强调了长期随访的必要性。
