News
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.

Puzzles, brain-training games and hobbies have long been said to stave off cognitive decline. But while some research has shown that intensive brain-training programs done over several weeks can reduce cognitive impairment, such interventions aren't very practical in daily life.
Why it matters: A large study shows that everyday activities like reading, socializing, and doing puzzles can help preserve cognitive health.
Hearing aids show promise for cognitive recovery, but dementia prevention remains unproven
People who live long enough have a high chance of losing some of their hearing as they grow older. By age 60, about one in three adults has presbycusis, an age-related decline in hearing caused by changes inside the ear…
Why it matters: Hearing aids show potential for helping cognitive recovery, though their ability to prevent dementia is still unproven.
