How your driving might reveal early signs of Alzheimer's | BBC News
Everyone's driving changes as they age. But for some people, subtle differences emerge in how they control a vehicle, which scientists say are associated with the early stages of Alzheimer's disease.
In an experiment to find out whether these driving differences can be detected using Global Positioning System-based (GPS) location-tracking devices, a group of over-65s in Washington State in the US agreed to have their driving closely monitored for one year.
What the researchers wanted to find out was whether just studying the driving habits of this group alone could reveal the start of the disease - without the need for invasive or expensive medical procedures.
Using the results of the driving data, they were able to design a model that could forecast someone's likelihood of having preclinical Alzheimer's using merely their age and their GPS driving data. It proved to be 86% accurate.
