29. How does a sleep center diagnose sleep problems?

Sleep centers employ physicians and others who are experts in problems that affect sleep. If the sleep specialist needs more information, he or she may ask you to undergo an overnight sleep study, also called a polysomnogram, and/or a sleepiness, or a nap test. A polysomnogram measures brain waves, heart rate, breathing patterns, and body movements.

A common sleepiness test is the multiple sleep latency test. During this test, the person has an opportunity to nap every 2 hours during the daytime. If the person falls asleep too quickly it may mean that he or she has too much daytime sleepiness.
