driving characterization using leukoaraiosis grading and personal measurements of traffic accidents for older drivers

脑白质疏松症约占中老年人的30%，被认为是脑老化的一个标志。多因素Logistic回归分析显示，双侧脑白质疏松症与交通事故，尤其是十字路口撞车有显著相关性。在高知驾驶执照中心的驾驶过程中，与没有脑白质疏松症的驾驶员相比，患有双侧脑白质疏松症的老年驾驶员在右转时，汽车的转向熵显着增加，这意味着转向的平稳处理。为定量评价安全驾驶所需的认知、判断、操作等额叶功能，研制了一种新的驾驶能力测验。根据高龄和脑白质疏松二分法的交叉分类，该测试可以预测特定类型的交通事故。脑白质疏松症可能是与高度老龄化一样的危险驾驶特征之一。

Leukoaraiosis, approximately 30% of middle-aged and older people, has been regard as a sign of brain-aging. Multiple logistic regression analysis showed a significant association between bilateral leukoaraiosis and traffic accidents, especially crossroad crashes. Older drivers with bilateral leukoaraiosis possessed a significant increasing in steering entropy of an automobile, which means smooth handling of steering, in comparison with those without leukoaraiosis, when turning right in the driving course of Kochi Driving License Center. A new driving ability test has been developed for quantitative evaluation of frontal function, composing of cognition, judgment, and manipulation, necessary for safe driving. According to cross-classification of dichotomy of high age and leukoaraiosis, this test could predict a specific type of traffic accidents. Leukoaraiosis may be one of dangerous driving characterization like high aging.
