Researcher Dr. Akshay Dwarakanath and colleagues wrote, “Worse lane position deviation is a marker of poor driving performance and this is significantly worse in [sleep apnea] patients who fail the simulator as compared to controls.”
The study included 129 adults with untreated sleep apnea and 79 adults without sleep apnea. All participants completed questionnaires about driving and were tested using a driving simulator.
Sleep apnea patients were more likely to say they had a higher risk of sleepiness while driving. They were also more likely to admit falling asleep while behind the wheel.
Sleep apnea patients were more likely to fail the driving simulator test, compared to the control group. Only 31 percent of sleep apnea patients passed the test, compared to 53 percent of the controls.
It is well known that patients with sleep apnea are two to six times more likely to crash in a car accident than individuals without the sleep disorder.
The researchers added, “Comparing with controls may be useful in advising patients whether they are at increased risk of an accident.”
Roughly two to four percent of the general population have sleep apnea. The condition can be successfully treated, but the important first step is to get diagnosed. If your partner complains about your snoring or if you have high blood pressure, are overweight, or are constantly tired even after eight hours of sleep, see your doctor for a sleep test.
