To evaluate a neurocognitive eye tracking task, the Bethesda Eye & Attention Measure (BEAM), for use in cognitive screening of patients with a history of mild traumatic brain injury (TBI).
US military TBI rehabilitation clinic.
DESIGN/PARTICIPANTS: Cross-sectional study of 191 military personnel receiving outpatient services related to history of mild TBI. Main measures: BEAM; neuropsychological screening measures of attention, processing speed, executive function, and memory.
Medium effect sizes were found for partial correlations (controlling for age) between key BEAM metrics and neuropsychological screening tests. Linear regression analyses demonstrated that BEAM saccadic eye movements and manual (button press) metrics each provided complementary value in measurement of cognitive performance, above and beyond effects of demographic factors and clinical characteristics.
This study provides initial support for the use of BEAM neurocognitive eye tracking in cognitive screening of adults with a history of mild TBI. BEAM saccadic metrics appear to be particularly well-suited for the assessment of visual attention. Study findings also highlight opportunities for greater cognitive sensitivity or testing efficiency that may be missed by tests measuring only one response modality at a time.
评估神经认知眼动追踪任务——贝塞斯达眼与注意力测验（BEAM），以用于有轻度创伤性脑损伤（TBI）病史患者的认知筛查。
美国军事 TBI 康复诊所。
设计/参与者：对 191 名接受与轻度 TBI 病史相关的门诊服务的军人进行的横断面研究。主要措施：BEAM；注意力、处理速度、执行功能和记忆的神经心理学筛查测试。
在关键 BEAM 指标与神经心理学筛查测试之间（控制年龄）进行部分相关分析时，发现了中等效应大小。线性回归分析表明，BEAM 的眼跳运动和手动（按钮按压）指标在测量认知表现方面提供了补充价值，超过了人口统计学因素和临床特征的影响。
本研究初步支持在有轻度 TBI 病史的成年人认知筛查中使用 BEAM 神经认知眼动追踪。BEAM 的眼跳指标似乎特别适合评估视觉注意力。研究结果还强调了可能会错过仅一次测量一种反应模式的测试的更大认知敏感性或测试效率的机会。
