In the study, adults who reported disrupted sleeping patterns in their 40s and 50s had more beta amyloid protein buildup, while those in their 50s and 60s with disrupted sleep had more tau protein tangles.
The researchers also found that the damage to the brain regions involved in daytime wakefulness is caused by a protein called tau, a hallmark of the memory-robbing disease, providing further evidence that tau plays a bigger role in the development of Alzheimer's compared with the more extensively studied amyloid protein. 
This provides more evidence that tau may play a larger role in Alzheimer's than the more extensively studied amyloid protein, the researchers noted.
"These results underscore that there are likely to be factors that we can modify to reduce the risk of cognitive decline, even if there is already evidence of build-up of the amyloid protein," he said.
Alzheimer's is the most common form of dementia, and autopsies have long found its telltale signs in the brain: sticky plaque from an abnormal buildup of amyloid protein, and tangles of another protein named tau.
This is the first FDA-approved treatment for patients with polyneuropathy caused by hATTR, a rare, debilitating and often fatal genetic disease characterized by the buildup of abnormal amyloid protein in peripheral nerves, the heart and other organs.
This pulsing, washing mechanism washes away that sticky, toxic, amyloid protein. And that is what Nedergaard discovered, that there is this pulsing, washing mechanism, washing away the amyloid protein at night.
The charity is currently funding a project at the University of Liverpool, led by Dr Jillian Madine, working to create a new way to track the spread of amyloid protein through the brain.
A new study finds that, in older people who show no signs of cognitive impairment, those with a sleep-wake cycle that is subtly off-kilter are more likely to have amyloid protein deposits in their brains, writes Melissa Healy A fitful night's sleep and a habit of daytime catnapping may be an early-warning sign of Alzheimer's dementia, according to new research conducted in humans and mice.
And Dr Shuzo Sakata at the University of Strathclyde in Glasgow is exploring whether activating certain brain regions can reduce the build-up of amyloid protein, a key factor in Alzheimer's disease.
Solanezumab targets a build-up of amyloid protein, which forms sticky plaques between brain cells thought to eventually kill them, leading to dementia.
Contrary to the understanding that an increase in amyloid protein is the first sign of the disease, this study suggests that a decrease in blood flow in the brain may be an earlier physiological sign of Alzheimer's disease.
