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. From the article:
"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."
