sonnejw0 writes "NewScientist is reporting a link between sleep deprivation and Alzheimer's Disease via an increased amyloid-beta plaque load thought responsible for a large part of the symptoms of the disease, in mice. Medication to abrogate insomnia reduced the plaque load. Also discussed is a recently discovered sleep cycle of amyloid-beta deposition in the brain, in which levels decrease while asleep. 'Holtzman also tried sending the mice to sleep with a drug that is being trialled for insomnia, called Almorexant. This reduced the amount of plaque-forming protein. He suggests that sleeping for longer could limit the formation of plaques, and perhaps block it altogether.'"
