What test is used to diagnose obstructive sleep apnea?

• A. Electroencephalography only
• B. Home sleep apnea test
• C. Magnetic resonance imaging
• D. Polysomnography

Answer: (D)

Polysomnography is the test used to diagnose obstructive sleep apnea because it provides a comprehensive overnight sleep study that records brain activity, eye movements, muscle tone, heart rate, breathing effort, airflow, and oxygen levels. This combination allows detection of apneas and hypopneas, quantification with the apnea-hypopnea index, and distinction between obstructive and central events. EEG confirms that the person is actually asleep and helps stage sleep, which is essential for accurate assessment. A home sleep apnea test uses fewer measurements and can miss some events or other sleep disorders, while MRI looks at structure rather than breathing during sleep, and EEG alone can’t diagnose apnea.
