Extreme daytime sleepiness is often a top symptom of Alzheimer’s disease but what, exactly, causes it? New research finally brings us an answer. A specific type of protein may cause daytime sleepiness in people with Alzheimer’s, according to a recent study. Many people with Alzheimer’s disease have a tendency to…

New sleep-promoting brain cells identified

On September 27, 2017, Posted by , In Buzz, By ,,, , With No Comments

Neurons that express the so-called Lhx6 gene may promote sleep by “switching off” other neurons. New research in mice identifies a range of neurons that may be involved in promoting sleep. The findings may soon change therapeutic practices for treating sleep disorders. Insomnia affects around 60 million people in the…

New cells found in the retina, paving way for jet lag therapy

On April 18, 2017, Posted by , In Buzz, By ,,,, , With No Comments

Our bodies have a natural way of adjusting themselves to the day-night cycle. Many of us know that these are our ‘biological clocks’ or ‘circadian rhythms.’ However, when behavioral or lifestyle changes interfere with this clock – such as in the case of jet lag – the result is sleepiness…

Sleep deprivation affects stem cells, reducing transplant efficiency, study finds

Drowsy mice make poor stem cell donors, according to a new study by researchers at the Stanford University School of Medicine. A sleep deficit of just four hours affects by as much as 50 percent the ability of stem cells of the blood and immune system to migrate to…
