The "MSLT" or Multiple Sleep Latency Test is a daytime nap test that objectively evaluates your degree of daytime sleepiness.
When you arrive in the morning, you will change into your comfortable clothing or sleep wear. The technician will paste electrodes to 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 5 nap opportunities spaced out every 2 hours throughout the day. The approximate times are 9 am, 11 am, 1 pm, 3 pm and 5 pm. During each nap opportunity you lie down in a quiet, darkened room and see how quickly you fall asleep. The technician will wake you after several minutes at which time you are asked to remain awake until the next nap time. 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.
