Frequently Asked Questions
23. 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. (Answer continues on next
