Study finds why poor sleep and high blood pressure may increase dementia risk
The ‘glymphatic system’ — the flow of cerebrospinal fluid during sleep to flush out toxins and waste materials from the brain — plays an essential role in keeping the brain healthy. A new study, using MRI scans, found that people with cardiovascular risk factors that impaired the function of the glymphatic system had an increased risk of dementia. The researchers suggest that improving sleep patterns to enhance glymphatic system function and treating cardiovascular risks could both help reduce dementia risk.
