  • Sleep is explained, finally

    From Alan Folmsbee@21:1/5 to All on Wed Nov 1 16:38:08 2023
    The cerebro-spinal fluid flows from the brain into the spine at night. When you lay down, the fluid in the brain increases 60% every few minutes and then retreats to the spine. Cerebrospinal fluid, a clear liquid surrounding the brain and spinal cord,
    moves through the brain along a series of channels that surround blood vessels.

    Alan finally produces something worthwhile in science. But I am going to have to wait to see if this news is reported in journals.

    Thanks

    Dr. Maiken Nedergaard and her colleagues at the University of Rochester Medical Center recently discovered a system that drains waste products from the brain. Cerebrospinal fluid, a clear liquid surrounding the brain and spinal cord, moves through the
    brain along a series of channels that surround blood vessels. The system is managed by the brain’s glial cells, and so the researchers called it the glymphatic system.

    The scientists also reported that the glymphatic system can help remove a toxic protein called beta-amyloid from brain tissue. Beta-amyloid is renowned for accumulating in the brains of patients with Alzheimer's disease. Other research has shown that
    brain levels of beta-amyloid decrease during sleep. In their new study, the team tested the idea that sleep might affect beta-amyloid clearance by regulating the glymphatic system. The work was funded by NIH’s National Institute of Neurological
    Disorders and Stroke (NINDS).

    Yes, I think one of the major symptoms of Alzheimers is the inability to sleep proper any more. So that if lack of sleep is bothering you, you likely have Alzheimers.
