Daytime Sleepiness and Driving Performance in Patients with Obstructive Sleep Apnea: Comparison of the MSLT, the MWT, and a Simulated Driving Task
Daytime sleepiness and driving skills in sleep apnea patients compared using sleep tests and a driving simulation

Abstract
A simulated driving test is associated with the ability to objectively measure daytime alertness in patients with severe obstructive sleep apnea.
- Driving-simulation performance was correlated with sleep latency measured by the Multiple Sleep Latency Test (MSLT) and more significantly with the Maintenance of Wakefulness Test (MWT).
- Patients with excessive daytime sleepiness or a history of car crashes performed worse on the driving simulator.
- The findings suggest that driving-simulation tests may help differentiate between sleepy and alert patients.
- Further studies are needed to clarify the relationship between simulated-driving performance and actual on-road crash risk.
