In which study does a patient try to stay awake in a darkened room?

• A. MSLT
• B. MWT
• C. NPSG
• D. REM behavior disorder study

Answer: (B)

Maintenance of Wakefulness Test measures a person’s ability to stay awake in a quiet, darkened environment with minimal stimulation. During the test, the patient is placed in a dim room and asked to remain awake for a set period (typically several trials lasting up to 40 minutes each), while monitoring confirms wakefulness. This focuses on wake maintenance rather than sleep onset. In contrast, the test that measures how quickly someone falls asleep during scheduled nap opportunities is designed to assess propensity to sleep, not staying awake. An overnight polysomnogram watches sleep architecture and events across the entire night, not specifically the ability to stay awake in darkness. REM behavior disorder studies concentrate on REM sleep and dream-enactment behaviors, not sustained wakefulness.
