Evaluation of the Impact of Sleep Apnea on Cerebral Volumetry According to Age

The goal of this project is to evaluate the impact of sleep apnea on the brain according to age. Our hypothesis is that adult apneic subjects would present local cerebral modification in the areas implied in cognition and memory, such as the hippocampus or the frontal areas, whereas elderly patients would present focal affects related to a deficit in the ventilatory and autonomic control without any major cognitive consequences. Understanding the consequences of sleep apnea according to age could permit to refine the indications of sleep apnea treatment, mainly in elderly patients.
