by Monash University Credit: Pixabay/CC0 Public Domain As little as 1% reduction in deep sleep per year for people over 60 years of age translates into a 27% increased risk of dementia, according to a study which suggests that enhancing or maintaining deep sleep, also known as slow wave sleep, in older years could stave off...

Credit: Matthew Walker A deep slumber might help buffer against memory loss for older adults facing a heightened burden of Alzheimer’s disease, new research from the University of California, Berkeley, suggests. Deep sleep,...
Linda Geddes Mon 13 Mar 2023 03.00 EDT Tonight, and almost every night, something amazing will happen inside your brain. As you turn off the light switch and fall asleep, you will be switching on the neurological equivalent of a dishwasher deep-clean cycle. First, the activity of billions of brain cells will begin to synchronise,...
By Peter Kendall May 28, 2022 at 7:32 a.m. EDT As he gets ready for sleep each night, Don Tucker slips on an electrode cap and checks a little computer on his bedside table. Many workers at the private lab, run by the professor emeritus at the University of Oregon, follow the same routine. The...
by Ekaterina Pesheva, Harvard Medical School Credit: Unsplash/CC0 Public Domain Healthy sleep is a basic physiologic need. In its absence, a myriad of processes in the body can go terribly awry. Chronic sleep problems have been linked to mental health disorders, cardiovascular disease, type 2 diabetes, and obesity, among other conditions. Yet, consistently achieving the...
ETH ZURICH IMAGE: THE SLEEP LOOP SYSTEM DEVELOPED BY ETH ZURICH RESEARCHERS EMITS A SOUND AT THE RIGHT TIME TO AMPLIFY THE SLOW BRAIN WAVES. CREDIT: SLEEPLOOP Many people, especially the elderly, suffer from abnormal sleep. In particular, the deep sleep phases become shorter and shallower with age. Deep sleep is important for the regeneration...
by Delthia Ricks, Medical Xpress Credit: Unsplash/CC0 Public Domain Sleep may be one of the most potent medicines for the brain, scientists are discovering, as they explore the inner labyrinths of the three-pound organ during deep sleep and dream cycles in both health and disease. Among the most active areas of sleep research are those...
Heard on All Things ConsideredJON HAMILTON The brain waves generated during deep sleep appear to trigger a cleaning system in the brain that protects it against Alzheimer’s and other neurodegenerative diseases. Electrical signals known as slow waves appear just before a pulse of fluid washes through the brain, presumably removing toxins associated with Alzheimer’s, researchers...
Sleeping time is sometimes considered unproductive time. This raises the question whether the time spent asleep could be used more productively – e.g. for learning a new language? To date sleep research focused on the stabilization and strengthening (consolidation) of memories that had been formed during preceding wakefulness. However, learning during sleep has rarely been...
