Sleep may enhance the brain’s ability to remove harmful waste. Poor or disrupted sleep could raise dementia risk. The brain possesses its own system for removing waste, known as the glymphatic system, which is believed to become more active during sleep. When sleep is disrupted, this cleaning process may be impaired, slowing the removal of […]



Summary

Sleep is vital for brain health, facilitating waste removal through the glymphatic system, which is most active during sleep. This system clears harmful substances that can contribute to dementia. When sleep is inadequate or disrupted, the glymphatic system’s efficiency declines, potentially slowing the removal of these damaging waste products. This impaired waste clearance may elevate the risk of developing dementia over time, highlighting the critical role of quality sleep in maintaining cognitive function and preventing neurodegenerative diseases.
