From a MedPageToday online article:
“Amyloid is important in initiating disease, but the actual damage in the brain is probably due to the accumulation of tau,” Holtzman told MedPage Today. “Normally, tau protein is inside cells, but there is more and more evidence suggesting that its spread to different parts of the brain is responsible for the progression of Alzheimer’s disease.”
Two studies in January explored how sleep might be associated with Alzheimer’s tau pathology. The first, led by Brendan Lucey, MD, and David Holtzman, MD, both of Washington University in St. Louis, found that older adults who had less slow-wave sleep had higher levels of brain tau.
The findings, published in Science Translational Medicine, suggested that poor quality sleep in late life may signal deteriorating brain health.
Sleep patterns predicted amyloid and tau burden, reported Matthew Walker, PhD, of the University of California Berkeley, and co-authors, in June.
“Our data showed that rates of accelerating blood pressure elevation were significantly higher in women than men, starting earlier in life,” said Cheng, the Erika J. Glazer Chair in Women’s Cardiovascular Health, who also serves as director of Cardiovascular Population Sciences at the Barbra Streisand Women’s Heart Center. “This means that if we define the hypertension threshold the exact same way, a 30-year old woman with high blood pressure is probably at higher risk for cardiovascular disease than a man with high blood pressure at the same age.”

Death rates from cardiovascular disease among people between the ages of 45 and 64 are rising in cities all across the country, including in some of the most unlikely places.
In 2016, Samantha Harvey began to lose sleep. She tried everything to appease her wakefulness: from medication to therapy, changes in her diet to changes in her living arrangements. Nothing seemed to help.
