Driving Data Spots Cognitive Decline
27 Nov
Summary
- Subtle driving changes may predict dementia before medical tests.
- GPS data outperformed memory tests in spotting cognitive impairment.
- MCI patients drove less, avoided nights, and stuck to familiar routes.
Researchers have discovered that monitoring everyday driving habits using in-vehicle GPS data can help identify individuals at risk of dementia much earlier than conventional medical testing. The study indicates that these subtle changes in driving behavior, such as reduced driving frequency and avoidance of nighttime trips, are key indicators of cognitive decline.
The findings suggest that GPS tracking outperformed standard memory tests and demographic factors in predicting mild cognitive impairment (MCI), a precursor to dementia. Participants with MCI showed a consistent pattern of altering their driving behaviors over several years, adhering more closely to familiar routes and driving less often.
This non-invasive method offers a low-burden approach to assessing cognitive function, potentially allowing for timely interventions to prevent accidents and improve safety. While the study shows promise, researchers note the need to respect privacy and ensure ethical implementation, acknowledging limitations regarding the diversity of the participant pool.
