Mean Wakefulness Test (MWT)

The "MWT" or Mean Wakefulness Test is an objective test of your ability to stay awake during the day.

When you arrive in the morning, the technician will paste electrodes on your scalp to monitor brain wave activity. This enables the technician to determine when you fall asleep and how deeply you sleep.

The test consists of 4, forty minute sessions spaced out every 2 hours throughout the day. The approximate times are 9 am, 11 am, 1 pm and 3 pm. During each session you are asked to remain awake in a semi-reclined position in a room with dim lighting. The technician will let you know when the session is completed at which time you are asked to remain awake until the next session. After your study is completed, it is scored by a technician and interpreted by a sleep disorders physician. You will see your sleep disorders physician at your scheduled follow-up appointment.
