Childhood prevalence of OSA is around 50–100%, with this prevalence nearing 100% in adulthood. In a recent study of a large group of children with DS, 66% were found to have OSA on a sleep study (also called polysomnogram or PSG) and about half of these children presented with severe disease.

Two different scenarios are often seen: Scenario 1: Your child is snoring, moving all over the bed, working to breathe, waking up repeatedly throughout the night, and sometimes seems to stop breathing. He/she is just NOT getting a good night sleep. You bring up these concerns to your pediatrician and they refer you to an Ear, Nose, and Throat (ENT) doctor and removal of the tonsils and adenoids, commonly called a “T&A”, is recommended.
