Study Raises Questions About Sleep Tests
A new study could change the way doctors administer certain sleep tests. It looked at protocol used for detecting excessive daytime sleepiness (EDS) in adults who may fall asleep while driving.
Researchers found a 40-minute protocol to be more effective than a 20-minute interval. The study showed more people actually fell asleep during the longer duration. Results also suggest the test may not be completely reliable when the strong motivation to keep a driver's license enables individuals to overcome sleepiness during the test.
