There's a very interesting article that just came out last year called "Dysfunction of the glymphatic system might be related to iron deposition in the normal aging brain."

The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
There's a very interesting article that just came out last year called "Dysfunction of the glymphatic system might be related to iron deposition in the normal aging brain."
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
So, we're starting to see these links between iron levels being too high, the glymphatic system not being active enough and so forth, leading to sickness behavior, inflammation, and maybe even damage to neurons associated with aging.
