"Chronic Sleep Deprivation Disrupts Brain Waste Clearance, Heightening Dementia Risk"

Persistent poor sleep disrupts the glymphatic system, hindering cerebrospinal fluid clearance and raising the risk of dementia, according to new research from the University of Cambridge.

• A study analyzing brain structures of over 40,000 adults found that sleep deprivation impairs the glymphatic system, crucial for removing toxic waste like tau protein linked to Alzheimers disease.
• Researchers utilized advanced magnetic resonance imaging to observe how chronic sleep deprivation affects the brains ability to clear cerebrospinal fluid, increasing dementia risk factors.
• The findings underscore the importance of sleep quality, as the disrupted glymphatic system can exacerbate the accumulation of toxic materials in the brain, potentially accelerating dementia onset.
