The good news that made us stop, from seven days of small wins.
The long view
Researchers are attacking Alzheimer's from several directions at once: the biology of how it spreads, drugs that reprogram the brain's immune cells, and blood tests that could catch it years early.
Latest · Aug 30, 2026 A Mount Sinai-led team mapped 830,000 brain immune cells from 1,607 donors and identified a microglia subtype that expands to actively fight Alzheimer's disease as it progresses, giving future treatments a defense system to strengthen instead of only plaques to attack.
What’s next: Whether Cu(ATSM) replicates its amyloid-clearing effect in human Alzheimer's patients, whether BCG's protective amyloid shift can be confirmed in Phase III trials timed early enough to matter, whether a trial can show the shingles vaccine itself lowers dementia risk rather than simply tracking with people who were always going to stay healthier longer, whether a drug that calms the microglia-driven inflammatory response without touching plaques c
