"Scientists have discovered problems with the brain's ability to clear toxins, which they suggest could be why poor sleep and high blood pressure increase the risk of dementia. In a healthy brain, the glymphatic system clears out poisons and waste. It flushes cerebrospinal fluid (CSF) the clear liquid that cushions the brain through the brain along tiny channels around blood vessels. This fluid collects toxins and drains them out of the brain, keeping it clean and healthy."
"At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story. The Independent is trusted by Americans across the entire political spectrum.

We believe quality journalism should be available to everyone, paid for by those who can afford it.Your support makes all the difference."
Scientists discovered problems with the brain's ability to clear toxins, suggesting poor sleep and high blood pressure increase dementia risk. In a healthy brain, the glymphatic system flushes cerebrospinal fluid (CSF) through tiny channels around blood vessels to collect and drain toxins. Reduced sleep and cardiovascular problems impair glymphatic function, potentially increasing Alzheimer's risk by preventing clearance of amyloid and tau. A Cambridge-led study employed MRI scans to assess the glymphatic system. Small vessel disease in the brain accelerates neurodegeneration by disrupting this clearance. Quality journalism and public funding support on-the-ground reporting and free access to such findings.
