Central sleep apnea is when you stop breathing during sleep. It is caused by problems with how the brain controls breathing.

This is not the more common obstructive sleep apnea, which is caused by obesity or other problems and involves loud snoring.

Sleep apnea - central

Central sleep apnea usually occurs in people who are seriously ill. For example, it can occur in people with a variety of severe and life-threatening lower brain stem lesions. The brainstem controls breathing. As a result, any disease or injury affecting this area may result in problems with normal breathing during sleep or when awake.

Conditions that can cause central sleep apnea include:

• Bulbar poliomyelitis
• Encephalitis affecting the brainstem
• Neurodegenerative illnesses
• Stroke affecting the brainstem

Other causes include complications of cervical spine surgery, secondary radiation in the region of the cervical spine, severe arthritis and degenerative changes in the cervical spine or the base of the skull, or primary hypoventilation syndrome.

There is a form of central sleep apnea that commonly occurs in people with congestive heart failure. Finally, idiopathic central sleep apnea is when the apnea is not associated with another disease.
