Multiple studies in humans and mouse models indicate that sleep disruptions raise the risk of Alzheimer’s disease (AD) by increasing the accumulation of disease-relevant proteins such as amyloid-beta ...

A single mutation in a mouse protein has large effects on how the mice sleep and their level of wakefulness when conscious, a new study shows. The research could also shed light on the physiological ...

Trouble sleeping is common in other neurodegenerative diseases, but past research has only suggested that it occurs in patients with amyotrophic lateral sclerosis. Now, a new study has not only ...

Scientists at Stanford have identified a neural circuit crucial in sleep regulation patterns in mice, which could one day lead to better drugs and interventions for human insomnia. Their study, ...

The first unbiased genetic screen for sleep defects in mice has yielded two interesting mutants, Sleepy, which sleeps excessively, and Dreamless, which lacks rapid eye movement (REM) sleep. The ...

You may have wondered why some people seem to need less sleep. Is it in their genes? It turns out that it likely is. A number of so called short-sleeper genes, which are associated with little need ...
