Obstructive sleep apnea, defined as the recurring obstruction of the upper airway is documented in 24% of adult males and 9% of females. The highest incidence is in the sixth decade. Snoring accompany 24% of middle aged man and 14% of females of the same age. Sleep apnea with the central origin, defined as the transient and recurrent cessation of breathing during sleep, is less frequent than obstructive sleep apnea.
