Symptoms of Central Sleep Apnea

CSA has many of the same symptoms as obstructive sleep apnea, such as:

  • Daytime sleepiness
  • Chronic fatigue
  • Morning headaches
  • Waking up feeling unrested

However, central sleep apnea is not usually associated with snoring unless a person has obstructive sleep apnea as well.

If CSA is related to nervous system damage, you might notice other symptoms related to the nerve damage, including:

  • Difficulty swallowing
  • Changes in voice
  • Numbness or weakness in other areas of the body

Heart conditions commonly cause central sleep apnea, too, so if you have had heart failure or other major cardiovascular problems, you should suspect and be evaluated for central sleep apnea.

Medical Conditions That Can Cause CSA

Central sleep apnea is often secondary to other medical conditions, such as:

  • Brainstem or spinal injury or dysfunction
  • Parkinson disease
  • Obesity
  • Heart failure

Sometimes medications or treatments–including CPAP–can trigger this type of apnea.

Cheyne-Stokes Breathing

Cheyne-Stokes breathing is similar to CSA. In fact, some people classify it as a type of central sleep apnea. In Cheyne-Stokes breathing, your body gets into a breathing pattern where you breath quick and shallow during sleep, then gradually diminish breathing until you stop breathing altogether. It’s a cyclical pattern that can repeat every two minutes or so.

Cheyne-Stokes breathing can be caused by heart damage, kidney damage or failure, and even travel to high elevations.

Does Your Apnea Need Treatment?

Central sleep apnea is sometimes transitory and may not need treatment. This is especially true if your CSA is largely asymptomatic. If you aren’t feeling the effects, it may not be worth treating.

For many other cases of central sleep apnea, treatment is directed at the underlying condition, such as heart or kidney problems.

Central Sleep Apnea Treatments

Oral appliances and lifestyle interventions, such as weight loss or increased exercise are not effective on CSA. Oral appliances cannot treat central sleep apnea because the airway is not compromised, just the body’s breathing signals.

Treating central sleep apnea generally relies on CPAP. This ensures the body is constantly getting access to air, even when it stops breathing. Unfortunately, CPAP can also increase the severity of CSA, so that once people start on CPAP, they may come to depend on it. Supplemental oxygen and other forms of respiratory support may also be used for CSA.
