Central Sleep Apnea Syndromes (CSA)
CSA is another serious sleep apnea but less common than OSA. People with CSA have a clear upper airway however their brain doesn’t send proper signals to the muscles that control the breathing. Conditions that can cause or lead to CSA include:

  • Problems that affect the brainstem, including brain infection, stroke, or conditions of the cervical spine (neck)
  • Severe obesity
  • Certain medicines, such as narcotic painkillers
  • Heart failure
  • Living in a high altitude

Common Signs & Symptoms for CSA:

  • Observed episodes of stopped breathing or abnormal breathing patterns during sleep
  • Abrupt awakenings accompanied by shortness of breath
  • Shortness of breath that’s relieved by sitting up
  • Difficulty staying asleep (insomnia)
  • Excessive daytime sleepiness/drowsiness (hypersomnia)
  • Chest pain at night
  • Difficulty concentrating
  • Mood changes
  • Morning headaches
  • Although snoring indicates some degree of airflow obstruction, snoring also may be heard in the presence of CSA. However, snoring may not be as prominent with CSA as it is with OSA.
