Multiple Sleep Latency Test and Maintenance of Wakefulness Test

Degrees of excessive daytime sleepiness can be quantified by obtaining a comprehensive history in conjunction with various diagnostic studies, such as an overnight polysomnography, the multiple sleep latency test, and the maintenance of wakefulness test. Although the multiple sleep latency test and maintenance of wakefulness test are laboratory-based assessments of sleepiness and wakefulness, respectively, these findings on these tests may not always correlate with patient safety in the workplace or while driving. Further research is needed to improve the diagnostic accuracy of our assessments of excessive daytime sleepiness.
