What's happening in Alzheimer's care, research funding, and treatment — summarized simply, each item linked to the original reporting.
Free to read, “May need a subscription” and “Archived copy”: what they mean
Whether an article is free to read is a guess, not a test of your access. Each item is one of three:
- No label: free to read (304 of 349). The publisher’s page marks it free, or the outlet publishes free to read: Medical Xpress, ScienceDaily, NIH (incl. NIA and PMC), Alzheimer's Association, Alzheimer's News Today, NPR, Alzheimer's Disease International, or a .gov site.
- May need a subscription (11 of 349). The publisher’s own page marks the article as not free to read, or — when the page says nothing — the outlet sells subscriptions: The New York Times, STAT, Scientific American, The Washington Post, The Wall Street Journal, Financial Times, The Economist, Bloomberg, The Atlantic, The New Yorker, Wired, Los Angeles Times, The Boston Globe, The Times, The Telegraph, New Scientist, Endpoints News, Science. Each badge says which.
- “Free to read? Not known” (34 of 349). The outlet is on neither list and its page said nothing. We do not call these paywalled.
Archived copy links go to a copy the Internet Archive (web.archive.org) saved, dated the day it was saved. We show one only where the Internet Archive reported a working saved copy when we checked; an archived copy of a subscription article sometimes shows only its opening. 265 of 349 items have one.
Mediterranean diet may boost tiny proteins that protect the heart and brain
Scientists have uncovered a surprising new clue to why the Mediterranean diet is so good for the heart, brain, and healthy aging. Researchers at USC found that older adults who closely followed the diet had higher levels of two tiny proteins, humanin and SHMOOSE…

A surprising two-year clinical trial found that fish oil supplements successfully delivered omega-3s to the brain but failed to improve memory or protect against Alzheimer's-related brain shrinkage. …
Just 3,000 steps a day may help slow Alzheimer's, scientists find
Walking just 3,000 steps a day could help slow Alzheimer’s-related brain changes, according to new research. Scientists discovered that physical activity was linked to less buildup of harmful tau proteins and nearly half the cognitive and functional decline…

Scientists have uncovered an unexpected culprit behind sleep loss in Alzheimer’s disease: overactive immune cells in the brain. By temporarily removing these cells, researchers restored more than two hours of sleep per day in mice, revealing a promising new target for treatment.

A large health-record analysis found that glucosamine use was associated with a 25% higher likelihood of mild cognitive impairment progressing to dementia. …

Frequent micro-awakenings during sleep were linked to higher genetic risk for Alzheimer’s in healthy middle-aged adults who had no symptoms. …
Read at ScienceDaily → Archived copy (28 Sep 2026), Internet ArchiveThis common vitamin was linked to 13% better cognitive scores
Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test than those taking none. …

Exercise and healthy blood sugar levels in midlife may help slow cognitive decline decades later. Physical activity appeared especially beneficial for Mexican American adults, suggesting that some brain-protective factors may differ across populations.

A gene involved in the brain’s overnight cleaning system may change how strongly poor sleep affects Alzheimer’s-related brain changes. The findings point toward more personalized prevention strategies based on both genetics and sleep habits.

Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. …

Fish oil supplements successfully delivered omega-3s to the brain, but a two-year study found no meaningful benefits for memory, cognition, or Alzheimer’s-related brain changes. …
Popular joint supplement glucosamine linked to faster Alzheimer’s progression
A major study suggests glucosamine, a popular supplement for joint pain, could be linked to faster progression from mild cognitive impairment to Alzheimer’s disease. …

Scientists in Japan have created powerful new vitamin K-based compounds that may help the brain regenerate lost neurons — a breakthrough that could one day change how diseases like Alzheimer’s and Parkinson’s are treated. …
Read at ScienceDaily → Archived copy (7 Oct 2026), Internet ArchiveThis simple amino acid supplement greatly reduces Alzheimer’s damage
A new study suggests a surprisingly simple compound could help fight Alzheimer’s disease. Researchers found that arginine—an inexpensive amino acid already considered safe—can reduce the buildup of toxic amyloid proteins in the brain, a hallmark of the disease. …
Read at ScienceDaily → Archived copy (4 May 2026), Internet ArchiveJust 5 weeks of brain training may protect against dementia for 20 years
A simple brain-training program that sharpens how quickly older adults process visual information may have a surprisingly powerful long-term payoff. …
Hearing aids didn’t boost memory tests but dementia risk dropped
A long-term study of older adults with moderate hearing loss found that hearing aids did not lead to better performance on memory or thinking tests, but the story did not end there. …
