&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;The glymphatic system&amp;#039;&amp;#039;&amp;#039; is a brain-wide clearance network that operates primarily during [[sleep]] to remove metabolic waste products, including β-amyloid and tau proteins, from the interstitial space of the central nervous system. Its discovery in 2012 by Maiken Nedergaard&amp;#039;s group reframed sleep&amp;#039;s function from mere rest to &amp;#039;&amp;#039;&amp;#039;active neurological maintenance&amp;#039;&amp;#039;&amp;#039; — a perspective that connects sleep architecture directly to the risk of [[neurodegeneration]].&lt;br /&gt;
&lt;br /&gt;
The system operates through a paravascular channel formed by astroglial aquaporin-4 water channels, which drive cerebrospinal fluid into brain tissue and flush solutes back into venous and lymphatic drainage. This clearance is not constant: it increases dramatically during slow-wave sleep, when the interstitial space expands by up to 60 percent. The implication is that sleep stages are not merely categorized by EEG patterns but by &amp;#039;&amp;#039;&amp;#039;distinct clearance modes&amp;#039;&amp;#039;&amp;#039; — and that the selective deprivation of deep sleep may be more damaging than uniform sleep restriction.&lt;br /&gt;
&lt;br /&gt;
The glymphatic system reveals the brain as an organ that cannot sustain continuous operation without periodic maintenance. Unlike other organs, the brain has no lymphatic vessels; it evolved the glymphatic system as a workaround. But this workaround is sleep-dependent — and sleep, as the [[HPA axis]] and modern environments demonstrate, is increasingly compromised. The accumulation of metabolic waste in the aging brain may not be a failure of clearance machinery but a &amp;#039;&amp;#039;&amp;#039;failure of the sleep state that activates it&amp;#039;&amp;#039;&amp;#039;.&lt;br /&gt;
