Insomnia may signal future Alzheimer’s

A person who has trouble sleeping can find Alzheimer’s disease in the near future , scientists from the University of Washington’s Mditsin School found out, RBC reports.  

Studies in mice have shown that during the formation of amyloid deposits in the brain, the animals experienced failures in the natural sleep cycle.

In 2009, a study by David Holtzman also revealed the opposite pattern: with severe lack of sleep, the amount of beta-amyloid increased in healthy mice, and in patients with animal wakefulness with a knocked-out sleep rhythm provoked a further increase in the number of amyloid plaques.  

The usual sleep-wake cycle for mice is 40 minutes of sleep every 20 minutes. With the initial effects of amyloid accumulation, mice sleep 10 hours less hourly.

Researchers from Washington conducted a meaningful experiment on genetically modified mice predisposed to the formation of protein deposits. The animals that received the anti-amyloid vaccine felt good, no plaques formed, and the sleep cycle remained normal.
