Can driving habits predict Alzheimer's disease according to the study?

Yes, the study found that specific driving patterns can predict cognitive decline, a precursor to Alzheimer's, with high accuracy.

What driving changes did researchers observe in people with cognitive decline?

Individuals with mild cognitive impairment drove less, avoided nighttime driving, and favored familiar routes.

Is driving data more effective than memory tests for identifying cognitive risk?

Researchers found that driving data alone or combined with other factors was more effective than memory tests and age alone.

Driving Habits Hint at Alzheimer's Risk

Summary

Driving patterns can predict cognitive decline with 82% accuracy.
Older drivers with impairment drove less, especially at night.
Driving data improved cognitive decline prediction accuracy.

New research suggests that alterations in driving behavior could be a significant early warning sign for cognitive decline, including Alzheimer's disease. A study utilizing GPS tracking devices found that individuals with mild cognitive impairment demonstrated distinct driving patterns. These changes included reduced overall driving frequency, a tendency to avoid driving at night, and a preference for well-known routes, differentiating them from cognitively healthy peers.

The study, involving participants averaging 75 years old, tracked driving habits over three years. Results showed that analyzing metrics like trip distances, speed limit adherence, and routine variation could predict mild cognitive impairment with 82% accuracy. Incorporating this driving data alongside age, cognitive test scores, and genetic factors boosted predictive accuracy to 87%, significantly outperforming predictions based on cognitive tests and genetic risk factors alone.
