Healio (9/8, Gramigna) reports research suggests that “sleep durations outside of a normal range worsened amyloid beta burden and cognition, underlining the importance of sleep in older adults,” investigators concluded after analyzing “data of 4,417 participants (59% women; mean age, 71.3 years) of the Anti-Amyloid Treatment in Asymptomatic Alzheimer’s Disease study, which is ongoing in 67 sites across the U.S., Canada, Australia and Japan.” The study revealed “a linear association between self-reported shorter sleep duration and higher amyloid beta burden, as well as an association between short sleep duration and reduced cognition, largely in memory domains.” The findings were published online in JAMA Neurology.
