What does a polysomnogram primarily assess?

A polysomnogram is a comprehensive test used to diagnose sleep disorders by monitoring various physiological parameters during sleep. It primarily assesses sleep patterns and the physical factors that influence sleep quality and duration. By measuring brain waves, oxygen levels, heart rate, breathing patterns, and eye and leg movements, a polysomnogram provides insights into how well a person sleeps and identifies any disturbances or irregularities that may occur throughout the night.

Understanding sleep stages and cycles, as well as the physiological responses during these stages, is crucial in diagnosing conditions such as sleep apnea, insomnia, and other sleep-related disturbances. The detailed data collected helps clinicians create tailored treatment plans to improve the patient's sleep quality and overall health.

In contrast, assessing motor functions, electrical activity of muscles, or heart health during exercise involves different types of tests that focus on specific bodily functions rather than the comprehensive evaluation of sleep dynamics that a polysomnogram provides.
