1 Obstructive sleep apnea is caused by the collapse of the airway during sleep.  The complications of obstructive sleep apnea include high blood pressure, strokes, heart disease, automobile accidents, and daytime sleepiness as well as difficulty concentrating, thinking and remembering.
Central sleep apnea is much less common. It is caused by a problem in the central nervous system, most often a failure of the brain to signal the airway muscles to breathe. In such cases, oxygen levels drop abruptly and usually the sleeper wakes with a start. Often people with central sleep apnea recall waking up. They generally experience less sleepiness during the day than people with obstructive sleep apnea. Heart disease, and, in particular, heart failure, is the most common cause of central sleep apnea.
