Somnology is a medical specialty regarding the diagnosis and therapy of sleep disorders and disturbances. It can be normal to have trouble sleeping from time to time, but if you are having trouble sleeping most nights, you may have a sleep problem. Common sleep disorder diagnoses include:

  • Narcolepsy
  • REM Behavior Disorder
  • Sleep Apnea
  • Obstuctive Sleep Apnea



After reviewing your sleep history, the doctor may refer you to a specialized sleep lab, where trained technicians will perform a sleep study. Sleep studies are tests that monitor your sleep, either overnight or during a series of naps during the day. These tests are painless and used to diagnose sleep problems.

Common sleep studies conducted at night, called “overnight studies,” are Basic Polysomnography, Continuous Positive Airway Pressure Trial (CPAP), and Split Night Study. Common studies conducted during the day include Multiple Sleep Latency Test (MSLT) and Maintenance of Wakefulness Test (MWT).

If you are scheduled for one of these procedures, please see our preparation page for more information of what to do before a sleep study.
