老年人的白质超强度 (WMH) 显著损害驾驶,减少复杂性,增加认知能力下降的风险. 后部WMH特别影响驾驶性能,这表明它在道路安全方面发挥着生物标志物的作用.
科学领域:
- 神经成像是一种神经成像.
- 老年学是一门学科.
- 道路交通安全 道路交通安全
背景情况:
- 白质超强度 (WMH) 影响认知储备,并可能加速痴呆.
- WMH的严重程度与老年人 (OA) 停止驾驶有关.
- 特定区域的WMH分布提供了对认知和功能影响的见解.
研究的目的:
- 研究WMH对复杂认知表现的纵向影响,使用OA中的自然驾驶行为.
- 弥合了解微妙的结构性大脑变化如何影响现实世界的驾驶功能方面的差距.
主要方法:
- 分析212个认知完整的OA (年龄≤65岁) 来自DRIVES项目队列的3TMRI扫描.
- 使用车载数据记录器对16个驾驶指标进行了长度评估,平均为6.1年.
- 使用深度学习量化WMH体积和区域特定分布,使用线性混合效应模型进行分析.
主要成果:
- 增加的WMH负担与旅行频率下降,离家近的旅行减少,独特的目的地减少,以及随着时间的推移降低驾驶度相关.
- 后部WMH (,) 显著降低了驾驶复杂性,影响了视觉处理和空间意识.
- 随着认知障碍,WMH对驾驶的影响加剧,导致硬制动和撞击事件的增加.
结论:
- WMH显著影响OA驾驶行为,减少复杂性和自我调节.
- 后部WMH表明阿尔茨海默病病理在驾驶能力下降中的作用.
- WMH作为一种潜在的生物标志物,用于识别有危险驾驶和过早停止驾驶风险的个体.
