Older adults cope with sleep deprivation better than young adults, U.S. researchers said. The older adults -- ages 59-82 years -- showed more resiliency to total sleep deprivation than young adults -- ages 19-38 years -- on a range of measures of cognitive performance, including working memory, selective attention/inhibition, and verbal encoding and retrieval. Performance of young adults significantly declined on all three tasks during total sleep deprivation while that of older adults did...

High-quality sleep is correlated with better grades, especially math, but sleeping late on the weekend is linked to worse grades, U.S. researcher said. The study found that higher math scores were related to greater sleep quality, less awakenings and increased sleep efficiency, but higher English and history scores were associated with less difficulty awakening. Principal investigator Jennifer C. Cousins, a postdoctoral fellow at the University of Pittsburgh Medical Center, said the results...

Two sleep-stage transition types were associated with higher mortality risk: wake-to-non-REM and non-REM-to-wake.According to lead author Alison Laffan,...

According to a research abstract that will be presented on Wednesday, June 10, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, caffeine use prevents increased risk taking that occurs after several nights of total sleep deprivation.Results indicate that despite extreme sleep deprivation, participants who had consumed caffeine did not exhibit increased risky behavior on the Balloon Analog Risk Task (BART), a computerized measure of impulsive risk-taking....

People who sleep less than five hours or more than nine hours per night are at greater risk for diabetes, U.S. researchers found. Lead author Girardin Jean-Louis of the State University of New York's Downstate Medical Center said the findings suggest both patients who have excessive or insufficient sleep time have increased risk for developing diabetes. The prevalence of diabetes was 12 percent for blacks and 8 percent for whites, and the prevalence of obesity -- body mass index of 30 or more...
