Sleep Studies (Polysomnography)
Polysomnography, also called a sleep study, is a test used to diagnose sleep disorders. It records your brain waves, the oxygen level in your blood, heart rate and breathing, as well as eye and leg movements during.
In addition to helping diagnose sleep disorders, polysomnography may be used to help adjust your treatment plan if you've already been diagnosed with a sleep disorder.
Multiple Sleep Latency Test (MSLT) measures how soon a person falls asleep in a quiet environment, and helps on the diagnosis of sleep disorders including narcolepsy.
