To assess the effects of auditory-verbal distraction on real-world driving safety and vehicle control among drivers with Parkinson disease.
Evaluated 71 licensed, active drivers with mild-to-moderate Parkinson disease and 147 elderly controls without neurologic disease on cognitive, visual, and motor batteries.
Assessed at-fault safety errors and vehicle control in an instrumented car on a four-lane interstate highway during baseline driving and an auditory-verbal task (Paced Auditory Serial Addition Task).
Drivers with Parkinson disease had higher odds of increased safety errors during distraction than controls (adjusted OR = 2.62, 95% CI [1.19, 5.74], p = 0.016), with errors increasing in 28.2% of the disease cohort versus 15.8% of controls.
Distraction responses were significantly more heterogeneous in Parkinson disease (p < 0.001), remaining stable in 54.9% (vs 80.8% in controls) and decreasing in 16.9% (vs 3.4% in controls).
Within the Parkinson group, worsening safety performance under distraction was predicted by lower cognitive flexibility, poorer verbal memory, reduced postural control, and greater daytime sleepiness.
