english: A series of recent clinical studies suggest that among patients who haven't yet developed Alzheimer's disease, worsening sleep quality and sleep duration are associated with a greater amount of amyloid-beta building up in the brain, and while it's important to point out that these studies don't prove that lack of sleep or poor sleep cause Alzheimer's disease, they do suggest that the failure of the brain to keep its house clean by clearing away waste like amyloid-beta may contribute to the development of conditions like Alzheimer's.
non_english: Niz nedavnih studija pokazuje da je kod pacijenata kod kojih se nije sasvim razvila Alchajmerova bolest smanjenje kvaliteta i trajanja sna povezano sa povećanim nagomilavanjem amiloid-bete u mozgu. Važno je napomenuti da iako ove studije ne dokazuju da loš san ili njegov nedostatak izazivaju Alchajmerovu bolest, ukazuju da nemogućnost mozga da ukloni otpade poput amiloid-bete može da doprinese razvoju bolesti kao što je Alchajmerova.
