A new study using Framingham Heart Study data found that a brain health score derived from a single night of sleep brain-wave recordings at midlife predicted cognitive performance an average of 12.6 years later.
A randomized crossover trial published in Nature Communications provides the first direct human evidence that the brain's glymphatic system clears Alzheimer's-linked proteins during sleep — and that one night of sleep deprivation measurably impairs the process.
A new study from Oregon Health & Science University found that regularly getting less than seven hours of sleep is more strongly associated with shorter lifespan than poor diet, lack of exercise or social isolation.
