| Research Abstract |
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.
