Longitudinal Study of Excessive Daytime Sleepiness


The natural history of daytime sleepiness in older adults is poorly characterized despite the high prevalence of this complaint. The specific aim of this study is to describe the prevalence, remission and incidence of the subjective complaint of excessive daytime sleepiness, and identify the factors that increase the risk of developing excessive daytime sleepiness. Our hypothesis is that the presence of medical co-morbidities strongly influences the incidence of excessive daytime sleepiness. In addition, we will also measure objective sleep parameters via wrist actigraphy to determine if changes in sleep pattern are associated with excessive daytime sleepiness.
