Determining the nature and extent of your sleep disorder may require one or several tests. Sentara’s sleep centers deliver state-of-the-art testing and interpretation by highly skilled physicians and technologists. Types of Sleep Disorders EvaluationsOvernight sleep study
This all-night, outpatient study involves recording various functions like heart rate, breathing, brain activity and limb movement. MSLT (Multiple Sleep Latency Test)
This test is often used to diagnose narcolepsy. Testing consists of a series of daytime naps that generally follows an overnight sleep study. The length of time it takes a patient to fall asleep can be determined. A driving simulator test may also be conducted as part of this assessment. Driving Simulator Testing
For patients with excessive daytime sleepiness, we can measure their ability to perform a computer-simulated driving test. Comparing the results to normal drivers and results from other patients helps us to determine the degree of risk the patient has when driving. The driving simulator also helps to measure the effectiveness of the various treatments for sleepiness. (Driving simulator test is available through the Sentara Norfolk General Hospital/EVMS Sleep Disorders Center
only.) Insomnia evaluation
Evaluation is conducted with Board-Certified Sleep Specialists.
