Symptoms:

Persons with central sleep apnea have episodes of disrupted breathing during sleep.

Other symptoms may include:

• Chronic fatigue
• Daytime sleepiness
• Morning headaches
• Restless sleep

Other symptoms may occur if the apnea is due to a neurological condition. Symptoms depend on the underlying disease and what parts of the nervous system it has affected, but may include:

• Difficulty swallowing
• Voice changes
• Weakness or numbness throughout the body

Signs and tests:

The health care provider will perform a physical exam. Tests will be done to diagnose an underlying medical condition. A sleep study (polysomnogram) can confirm sleep apnea.

Other tests that may be done include:

• Echocardiogram
• Lung function studies
• MRI of the spine or neck
