In the field of sleep disorders medicine it has become clear that the most common presenting complaint in sleep clinics is daytime sleepiness. In published reports from sleep clinics, 51% of all patients complain of EDS (excessive daytime sleepiness) and 90% of apnea patients have this complaint. A second major impetus for research on EDS has been the introduction of an objective method of quantifying sleepiness. The Multiple Sleep Latency Test (MSLT) measures the latency to polygraphically defined sleep in 20-minute opportunities given in a standard environment at 2-hour intervals across the day. The MSLT has proven to be a reliable measure, free of the practice or motivational problems associated with the more behavioral measures of alertness. Finally, the MSLT has been validated in varieties of experimental and clinical paradigms.
