Naturalistic Driving Detects Mild Cognitive Impairment
Researchers at Arizona State University and collaborators in a 2026 JMIR Med Inform paper develop deep learning models that use naturalistic in-vehicle GPS, accelerometer, and gyroscope data to detect mild cognitive impairment (MCI). In a study of 22 participants, full-trip models achieved 78% accuracy and 77% AUC, outperforming turn-only inputs; the authors propose a frequency-based risk score for interpretable screening. Findings support scalable, noninvasive early cognitive monitoring.
Key Points
- 1Achieved 78% accuracy and 77% AUC using full-trip naturalistic driving data (N=22)
- 2Demonstrates full-trip data capture episodic MCI better than turn-only inputs
- 3Suggests frequency-based risk score enables interpretable, scalable screening in clinical and community settings
Scoring Rationale
Solid peer-reviewed application using naturalistic driving data, demonstrating practical accuracy, but small sample size and limited cohort constrain generalizability.
