A maintenance of wakefulness test, or MWT, determines daytime wakefulness in order to diagnose a sleep disorder or test the effectiveness of a patient’s current sleep disorder treatment. Typically, a MWT is conducted in conjunction with a polysomnogram, usually performed the night before.  

A MWT usually lasts all day long and requires four different collections of data spaced at two-hour intervals. The patient must stay awake for the duration of the test. For data collection, sensors will record functions like eye movement, brain wave activity, heart activity, and muscle contractions. Then a sleep specialist uses this information to determine your difficulty maintaining wakefulness in order to evaluate your sleep disorder treatment plan.
