What does the acronym EEG stand for in polysomnography?

In the context of polysomnography, EEG stands for electroencephalogram. This term refers to a test that measures the electrical activity of the brain. During a polysomnography study, electrodes are placed on the scalp to record brain waves, which are essential for diagnosing various sleep disorders. The EEG provides crucial information about the different stages of sleep, such as REM and non-REM sleep, by capturing the brain's electrical patterns through the night.

Understanding the importance of EEG in polysomnography is fundamental, as it helps to identify abnormalities, assess sleep architecture, and evaluate conditions like sleep apnea, insomnia, and other sleep-related disorders. The captured data guides clinicians in making informed treatment decisions to improve patient sleep quality and overall health.
