Researchers from Washington University found that driving habits may indicate early cognitive decline, as published in Neurology. Their study monitored around 300 older adults for over three years. They discovered that while driving behaviors appeared similar at first, those with mild cognitive impairment (MCI) adjusted their habits significantly over time, driving less frequently and choosing familiar routes.
Analyzing driving metrics revealed a predictive accuracy of 82% for MCI detection using GPS data alone. When combined with demographic and cognitive information, accuracy improved to 87% compared to the traditional approach, which only reached 76%.
Ganesh M. Babulal, the lead researcher, highlighted that this unobtrusive method could transform early intervention strategies, potentially identifying at-risk drivers before accidents occur. However, ethical considerations regarding privacy and autonomy must be addressed.
Most study participants were highly educated white individuals, which may limit the generalizability of the findings. The research was supported by the National Institutes of Health and the National Institute on Aging.
