Driving safety in Parkinson’s disease

Abstract

In this study, 39 patients with PD and 25 control subjects without neurologic disease completed testing in a driving simulator. PD patients had more total collisions on the driving simulator than control subjects (t = −3.7, p < 0.01). In PD patients, collisions were associated with Hoehn and Yahr stage (χ² = 12.4, p = 0.006) and correlated with Unified Parkinson’s Disease Rating Scale score (r = 0.5, p < 0.01).
