What is Polysomnography?
A Polysomnography (PSG) is a sleep test measuring a group of variables, including limb & body movement, brain activity, heart activity, and breathing patterns. A PSG can detect narcolepsy and sleep apnea, among other medical conditions. These tests are typically performed at a sleep medicine facility, conducted by a sleep specialist.
When You Should Get a Test Done
If you or a loved one have disturbances in your sleep patterns, wake up unable to breathe, or experience any kind of troubling behavior during sleep, notify your primary care doctor immediately. Depending on your doctor’s advice, you’ll likely be referred to a sleep specialist who will consult then administer one of several tests, including PSG.

What a Polysomnography Test Can Diagnose
PSG tests are multi-variable sleep studies designed to gather a large amount of information that includes:
- Brain Activity (EEG)
- Limb Movement
- Eye Movement
- Sleep Stages
- REM Activity
- Breathing Patterns
- Heart Rate
- Blood Oxygen
- Body Positioning & Behavior
Obstructive Sleep Apnea (OSA)
Obstructive sleep apnea occurs when muscles in the back of the throat block airflow, causing snoring. Several forms of OSA involve the blockage of air passages while sleeping. Common treatments for OSA include CPAP, BiPAP, APAP, dental devices, and surgery.
Narcolepsy is a neurological condition that affects the body’s ability to regulate sleep-wake cycles. Symptoms include loss of voluntary muscle control, excessive daytime sleepiness (EDS), hallucinations, sleep paralysis, and in some cases, insomnia.
REM Behavior Disorder
Rapid eye movement (REM) sleep behavior disorder is a condition that causes individuals to physically, sometimes violently, act out while sleeping. People that suffer from it may involuntarily swing their arms or scream while sleeping. REM behavior disorder generally occurs during unpleasant, vivid dreams.
