Gooneratne et al selected 289 people over 65 (nondemented, nondepressed), half of whom had excessive daytime sleepiness (EDS). All got polysomnograms and were followed for a mean of 14 years. Those with EDS and sleep disordered breathing (SDB) had a hazard ratio for mortality of 2.7, that fell to 2.3 after adjusting for covariates. People with EDS or SDB in isolation had no increased mortality risk. Sleep 2011;34:435-442.
