0080 TBI Time Since Injury: A Comparison Model Between Sleep Efficiency and Neurocognitive Performance

Abstract Introduction MTBI remains on one of the most prevalently reported brain injuries. Previous studies have shown an association between sleep efficiency, performance, and neurocognitive outcome. Reported time-since-injury (TSI) has also with outcome measures, some evidence suggesting status is significantly worse at 2 weeks post-injury. Here, we examined differences in self-reported efficiency various time points since injury among individuals who had sustained mTBI preceding year. Methods 190 Participants [71 male, 119 female], age M=24.48, SD=6.80 (HC, n=39) five mild TBI groups based post-injury, 2-weeks (2W, n=12), 1-month (1M, n=30), 3-months (3M, n=34), 6-months (6M, n=33), 12-months (12M, n=40) completed a cross-sectional study specific post-injury ranging from 1M, 3M, 6M, 12M). comprehensive Repeatable Battery for Neuropsychological Status (RBANS) were administered Pittsburg Sleep Quality Index (PSQI) assessment. Here analyzed subscale PSQI. Separate correlation analysis attention index each TSI group. Results The ANOVA showed main effect group, F(5,182) = 2.83, p=.017. Post Hoc comparisons LSD test that 12M group ­efficiency than HC 2W, 3M but did not differ 6M (p<.05). correlations RBANS marginally significant 2W (r(10)=-.467, p=.063, tailed), statistically (r(38)=-.266, p=.049, was associated performance those points. Conclusion differs across first year recovery mTBI. Notably, appear to any other appears be attentional capacity timeframes. This suggests interventions focus enhancing patients may prove promising facilitating recovery. Support (if any) W81XWH-12-1-0386
