Medical News Today looks at three key studies and their key findings that highlight and further confirm the connection between how poor sleep increases dementia risk.

The brain rinses away Aβ during sleep, powered by glymphatic flow from arteries to veins. In today’s Journal of Experimental Medicine, researchers led by Takeshi Iwatsubo at the University of Tokyo ...

We spend one-quarter to one-third of our lives sleeping, but while we rest, the brain remains hard at work, performing regular maintenance. Sleep is known to be important for learning and memory ...

Getting enough deep sleep might be the key to . In a series of recent experiments on mice, researchers discovered that deep sleep helps the brain clear out potentially toxic waste. The discovery ...

The brain’s built-in clearance system, called the glymphatic system, removes toxins from the brain through the flow of cerebrospinal fluid (CSF) via minuscule channels that trace blood vessels.

Once thought not to exist, the lymphatic system of our central nervous system is referred to as the glymphatic system and is made up of water channels, pores, and other clearance pathways. It is ...

Microinfarcts may be puny, but they pack a punch when it comes to brain cleaning, according to new research. In the March 15 Journal of Neuroscience, scientists led by Maiken Nedergaard, University of ...
