19/5000 (SYNAPSOT21) Predictive Factors of Sleep Apnea Syndrome in Down Syndrome

The obstructive sleep apnea syndrome (OSAS) is frequently reported in subjects with trisomy 21. The consequences of this syndrome are expressed in various disorders such as cognitive and cardiovascular alterations. It is also reported a premature exhaustion with the achievement of various professional or recreational activities, as well as an increase in the frequency of daytime sleepiness. In trisomy 21, there are factors that are systematically associated with obstructive apnea. The identification of these factors would make it possible to diagnose OSAS earlier, under-diagnosed in the population with trisomy 21 even though these OSAS are associated with increased cardiovascular risks. The aim of this study is to identify the predictive factors associated with sleep apnea in the trisomy population in order to propose early detection. OSAS treatment in a young adult with Down syndrome could reduce physical fatigue apparition during various activities, reduce daytime sleepiness, and have a positive impact on physical fitness, and therefore more broadly on health.
