What is Polysomnography?

Sleep disorders can have a serious adverse impact on life, and can affect a person in any age group. More than 80 types of sleep disorders are known to the scientists today. To evaluate and diagnose a sleep disorder, the physician may recommend a polysomnography test for the patient. Polysomnography or a sleep study is a comprehensive tracking and recording of the bio-physiological changes that occur during sleep.

In most cases, the polysomnography test is performed at night when the patient is like to experience marvelous sleep. However, an advanced sleep test lab will be able to accommodate patients with circadian rhythm disorders in order to conduct the test during daytime. The polysomnography or PSG test monitors several body functions including brain activity (EEG), eye movements (EOG), skeletal muscle activation (EMG), and heart rhythm (ECG) while the patient is asleep. The test also records the level of oxygen in the blood during sleep.

Why Undergo Polysomnography?

Polysomnography is performed with an aim to identify whether the sleep patterns are disrupted and what may be the causes for it. The normal sleep process begins with non-rapid eye movement (NREM) sleep stage. In this stage, the brain activity relaxes significantly, and the eyes do not move back and forth rapidly. Following one or two hours of NREM sleep, the brain waves become more active, and the rapid eye movement (REM) sleep stage begins. A person will typically go through four to six cycles of sleep at night.

Polysomnography procedure is designed to monitor these sleep stages to determine whether the normal sleep cycles and processes are disturbed, and in what pattern. A physician may advise the patient to undergo this test, if the patient is suspected to be suffering from sleep apnea, periodic limb movement disorder, narcolepsy, REM sleep behavior disorder, abnormal activities during sleep such as sleepwalking, or unexplained chronic insomnia.
