Sleep apnea, or difficulty breathing at night, is common among children with Down syndrome—affecting up to 80% compared to just 5% of the general pediatric population. Sleep apnea can negatively impact any child’s ability to function and learn, but for children with Down syndrome who have neurocognitive differences, good sleep may be even more crucial to their development. OAHI is a measure of the number of apnea events, or time a child stops breathing, per hour. The children in our study showed striking reductions in their sleep apnea events. We also feel this research offers a message of hope to parents of young children with Down syndrome who have worried about their children’s sleep apnea.
