Characterization of Geriatric Sleep Apnea Syndrome


The purpose of this study is to investigate the potential age-related differences in sleep apnea syndrome. We believe that sleep apnea is a fundamentally different process in the elderly than in younger subjects. A potential factor underlying the differences in sleep apnea in younger subjects as compared to older ones is the nature of the sleep apnea in terms of percent of hypopneas and central events. Additionally, we are interested in the severity of the sleep apnea, as measured by the respiratory disturbance index and oxyhemoglobin desaturation. Our study will test the hypotheses that geriatric sleep apnea is more severe and is characterized by more central events than sleep apnea in younger subjects. The finding of differences in the nature and severity of sleep apnea as a function of age will be a significant contribution to our understanding of sleep disorders in the elderly.
