Follow this healthy habit every day to prevent Alzheimer's disease

A new study published in the journal PLOS Biology reveals a new beneficial brain method that helps prevent Alzheimer's disease, which is deep sleep. Penn State University scientists have discovered that sleep-dependent brain activity - the kind that occurs during deep, restful sleep and non-rapid eye movement (NREM) ... NREM) - can help the body get rid of toxic proteins associated with Alzheimer's disease.

According to the eating well website, a healthy gut can help you get deep, high-quality sleep, so make sure you eat a healthy diet of foods rich in probiotics such as: yogurt and milk.

Extensive research has indicated that one way Alzheimer's disease develops is when levels of amyloid-beta (Aβ) and tau proteins build up in the brain, often over 10 to 20 years before formal diagnosis.

And this isn't the first research to hint at protein burden in the brain and the sleep link: In 2018, scientists found that a single night of sleep deprivation increases the load levels of Aβ in the brain.


Cerebrospinal fluid (CSF) can excrete these waste products from the body through the glymphatic system, which is part of the central nervous system, and deep sleep may help the brain eliminate these toxins associated with Alzheimer's disease.

During non-rapid eye movement (NREM) sleep, the kind that occurs when it's really hard to wake up because you're "too far", the brain produces slow, steady electrical waves that act as an internal cleaning mechanism.

"The study linked the coupling between global resting-state brain activity and cerebrospinal fluid flow to Alzheimer's disease," said Xiao Liu, assistant professor of biomedical engineering at Penn State University.

The study authors recommended adding sleep analysis to the Alzheimer's disease detection protocol.
