MSLT - Multiple Sleep Latency Test : An objective measure of manifest sleep tendency consisting of four or five naps at regular intervals during the day. It usually measures how long it takes to fall asleep and which stages of sleep are entered. Sleep-onset REM periods (SOREMPs) support a diagnosis of narcolepsy. (direct link)

MWT - Maintenance of Wakefulness Test : A test in which subjects are instructed to stay awake in a semi-reclined position in a dark room. The amount of time taken to fall asleep is considered an indication of the ability to stay awake. (direct link)
