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.

The first disease-modifying drugs for Alzheimer's disease offer patients the ability to slow cognitive decline by targeting amyloid plaques in the brain. But a new study suggests that not all patients have the same opportunity to receive these treatments.
How the biggest Alzheimer's risk gene disrupts the process of insulating neurons
One of the main ways that the APOE4 gene variant, the biggest genetic risk factor for late-onset Alzheimer's disease, undermines brain circuit function is by disrupting the process of insulating neurons with a fatty sheath that optimizes their electrical transmission.
