| Research Abstract |
We found out a significant association between leukoaraiosis and traffic crashes for healthy drivers who underwent MRI surveys as one of general health checkups and answered road traffic crash questionnaire. In particular, crossroad crashes were significantly involved in leukoaraiosis among various types of road crashes. The multiple regression analysis showed that adjusted odds ratios for involvement in crossroad crashes were 2.937 [95% confidence interval (CI), 1.260-6.847] for subjects with multiple leukoaraiosis. We also examined the relationship between leukoaraiosis and brain functions with driving simulation test making examinees move their right legs from an accelerator pedal to a brake pedal according to blue and red signal. Leukoaraiosis brought about a significant decline of accuracy and incline of processing speed fluctuation. Quantitative analysis of leukoaraiosis with MRI may be one of the useful measurements to prevent from traffic crashes.
