Deep sleep may help clear the brain of Alzheimer’s-related toxins


Sumary of Deep sleep may help clear the brain of Alzheimer’s-related toxins:

  • Retno Ayu Adiati/EyeEm/Getty Images A new study links sleep-dependent brain activity with the excretion of toxic proteins related to Alzheimer disease..
  • Research published in PLOS Biology suggests that global brain activity during deep sleep decreases Alzheimer -related toxin buildup..
  • It upholds previous findings indicating that low frequency brain waves produced during the non-rapid eye movement (NREM) sleep phase can play a vital role in clearing brain waste..
  • Dr. Xiao Liu, assistant professor of biomedical engineering at the Pennsylvania State University, led the study..
  • Alzheimer disease develops in line with increased levels of the proteins amyloid-β (Aβ) and tau in the brain..
  • Experts believe that cerebrospinal fluid (CSF) carries such waste products away from the brain through the glymphatic system, which is a system of channels in the central nervous system..
  • Glial cells, which make up a substantial amount of the brain total mass, work with blood vessels to help shield neurons from physical and chemical damage..
  • According to a 2021 review, impairments in glymphatic draining might lead to an extracellular buildup of waste products in the brain….
