Maintenance of Wakefulness Test (MWT)

Now that we have covered the editorial standards of the Sleep Foundation, let’s dive into the fascinating topic of the

Maintenance of Wakefulness Test (MWT). This test plays a crucial role in diagnosing sleep disorders and evaluating the effectiveness of treatment.

Explanation of the MWT and its purpose

The Maintenance of Wakefulness Test, as the name suggests, measures an individual’s ability to stay awake under controlled conditions. During the test, patients are asked to sit comfortably and try to stay awake for a predetermined period of time, usually in the range of 40 minutes to two hours.

This test is designed to assess daytime sleepiness and alertness, giving healthcare professionals valuable insights into a patient’s sleep-wake patterns.

Use of MWT in diagnosing sleep disorders and evaluating treatment effectiveness

Sleep disorders can have a significant impact on a person’s overall well-being and daily functioning. The MWT is an invaluable tool in diagnosing and monitoring these disorders.

By assessing a patient’s ability to stay awake, healthcare professionals can identify underlying conditions such as narcolepsy, excessive daytime sleepiness, or shift work sleep disorder. Furthermore, the MWT is also useful in evaluating the effectiveness of treatment interventions aimed at improving a patient’s alertness.

Debate and research on the effectiveness of MWT for assessing driving risk and non-sleep disorder conditions

Though the MWT is primarily used in diagnosing sleep disorders, there has been ongoing debate and research regarding its effectiveness in assessing driving risk and non-sleep disorder conditions. While some studies suggest that MWT scores correlate with driving performance, others argue that additional factors must be considered when evaluating driving risk.

Furthermore, researchers are also exploring the use of the MWT in conditions such as attention deficit hyperactivity disorder (ADHD) and chronic fatigue syndrome.

Comparison between MWT and multiple sleep latency test (MSLT)

While the MWT focuses on measuring an individual’s ability to stay awake, the Multiple Sleep Latency Test (MSLT) assesses daytime sleepiness by measuring how quickly a person falls asleep in a quiet and dimly lit environment. These tests serve different purposes and can complement each other in the diagnosis and evaluation of sleep disorders.

While the MWT is more relevant for assessing daytime alertness, the MSLT provides insights into the presence of excessive daytime sleepiness.

Scoring and interpretation of MWT results

After the completion of the MWT, the results are scored based on predefined criteria. These scores range from 0 to 40, with higher scores indicating better alertness and wakefulness.

Healthcare professionals interpret these scores in conjunction with other clinical information to make accurate diagnoses and recommendations. It is important to note that the interpretation of MWT results should always be done by qualified healthcare professionals, as they possess the expertise to assess the nuances of each individual case.

With this comprehensive guide, we hope to have shed some light on the Sleep Foundation’s editorial standards and the significance of the Maintenance of Wakefulness Test. By providing accurate and reliable information, we aim to empower our readers to make informed decisions about their sleep health.

Remember, a good night’s sleep is the cornerstone of a healthy and productive life.

How Maintenance of Wakefulness Test Works


Maintenance of Wakefulness Test (MWT) is a valuable tool used to assess an individual’s ability to stay awake during quiet and relaxed conditions. Understanding how the test works can help demystify the process and alleviate any concerns you may have.

In this section, we will delve into the various aspects of the MWT.

Timing and location of the MWT

The timing and location of the MWT are typically scheduled in consultation with a sleep specialist. It is important to schedule the test at a time when you are most likely to be alert and awake.

Typically, the MWT is conducted during the day, usually in the late morning or early afternoon. This ensures that your natural circadian rhythm and sleep-wake cycle align with the test conditions.

The test is usually conducted in a comfortable, quiet, and dimly lit room, similar to a sleep laboratory setting. Preparing for the MWT, including medication and caffeine restrictions

Before undergoing the MWT, it is important to follow any preparation instructions provided by the sleep specialist.

This may involve restrictions on certain medications that can affect sleep or alertness, as well as avoiding caffeine for a specific period of time before the test. Medications such as sedatives, stimulants, and certain antidepressants can potentially interfere with the results of the test.

It is crucial to communicate any medications or supplements you are taking with your sleep specialist to ensure accurate results.

Electroencephalogram (EEG) and equipment used during the test

During the MWT, electrodes are placed on your scalp to record brain activity using an electroencephalogram (EEG). The EEG measures the electrical activity in your brain through small electrodes that are attached to specific locations on your scalp.

These electrodes are painless and do not cause any discomfort. In addition to the EEG, other physiological measurements such as eye movements, muscle activity, and heart rate may also be recorded to gather a comprehensive understanding of your wakefulness and alertness patterns.

Procedure and instructions during the MWT, including wake trials and activities

The MWT is typically conducted in multiple sessions throughout the day. Each session lasts for a predetermined period of time, usually ranging from 40 minutes to two hours.

You will be asked to sit in a comfortable chair or lie in a bed, depending on the testing facility. The purpose of the test is to keep you awake, so you will be encouraged to engage in relaxed wakefulness activities such as reading, watching TV, or solving puzzles.

These activities are designed to mimic real-life situations where you need to stay awake and alert.

At periodic intervals, called wake trials, the sleep specialist will assess your level of alertness.

You will be required to signal to the specialist that you are awake by pressing a button or indicating in some other predetermined manner. This allows the specialist to monitor your wakefulness accurately and evaluate your ability to maintain alertness over time.

Scoring and analysis of MWT data by a sleep medicine physician

After the completion of the MWT, the collected data is analyzed and scored by a sleep medicine physician or specialist. The data is assessed based on predetermined criteria, which take into account the duration and consistency of wakefulness during each session.

The scoring system typically assigns scores ranging from 0 to 40, with higher scores indicating better alertness and wakefulness. These scores, along with other clinical information and observations, help the sleep specialist make informed diagnoses and recommendations for treatment or further evaluations.

Understanding the intricacies of the MWT can help alleviate any apprehensions or uncertainties you may have about the testing process. By actively participating and following the instructions provided by your sleep specialist, you can ensure the accuracy and effectiveness of the test results.
