What was done
This book chapter reviews the physiological mechanisms of the glymphatic system—a brain-wide network facilitating cerebrospinal fluid (CSF) and interstitial fluid (ISF) exchange—and summarizes evidence regarding its dysfunction across neurological disorders and potential therapeutic targets.
What was found
The abstract provides no quantitative data. It outlines that impaired glymphatic clearance is implicated in aging, sleep disruption, cerebral edema, stroke, traumatic brain injury, migraine, hydrocephalus, psychiatric conditions, and neurodegenerative disorders including Alzheimer, Parkinson, Huntington diseases, amyotrophic lateral sclerosis, and small vessel disease.
Why it matters
Synthesizing the biological mechanisms of brain waste clearance highlights potential therapeutic avenues aimed at preserving or restoring fluid exchange to mitigate neurodegenerative and acute neurological pathology.
Limits
The abstract describes a broad narrative overview rather than a systematic review or meta-analysis. No original empirical data, sample sizes, effect sizes, or specific search methodology are provided to evaluate the strength or consistency of the summarized evidence.
