What is a maintenance of wakefulness test?
The multiple sleep latency test is the test of choice for evaluating hypersomnolence during the day. It can also be useful in diagnosing narcolepsy. The test is performed during the day at one of our clinics. When you arrive for your appointment, a healthcare professional trained in sleep care will set up the equipment and remain with you throughout the test. You will be asked to take 4 or 5 naps at predetermined times and specific intervals.
The set-up of equipment involves sensors being applied to your head and face, allowing the healthcare professional to analyze how you fall and remain asleep during your naps. The sensors will record your brain’s electrical activity in order to identify the different sleep stages.
The test can detect sleep disorders such as:
- narcolepsy (sleepiness and sleep attacks during the day)
- hypersomnolence during the day
The data recorded during your multiple sleep latency test will be interpreted by a doctor trained in sleep care and forwarded to your attending physician.
Preparing for the test (adults)
IMPORTANT: You must fill out the following two documents before the test. You can fill them out online or on paper. It is important to print them and bring them with you to the clinic.
Sleep journal: Fill out 1 week before the test
List of medications: Fill out the morning of the test
In order to properly prepare for the test:
- Have your prescription and the two above-mentioned documents with you.

- Take your usual medications unless otherwise specified by the doctor.
- It is important not to use face cream or body lotion.
