What is a sleep study?

A sleep study (called a polysomnogram or PSG for short) is a test that records your physical state during various stages of sleep and wakefulness. A sleep study is commonly performed to investigate various symptoms that fall into a pattern indicating the presence of a physical sleep disorder. Of the dozen symptoms listed below, each one may be caused, in part, by a physical sleep disorder. PSG is the best test to diagnosis a physical sleep disorder.
