Dementia symptoms: Driving slower could be a sign – accurate in 90% of people

The study concluded: “The findings suggest that GPS driving may serve as an effective and accurate digital biomarker for identifying preclinical AD [Alzheimer’s disease] among older adults.”

However, the research team also noted there might be some limitations to their findings.

For example, the study only looked at a small sample of the population from the greater St Louis metropolitan area in America, so these findings may not be applicable to other regions.

Plus, the researchers also noted that it’s possible that a small number of car trips was actually taken by friends and family members instead of the dementia patients.
