The brain’s cleanup crew is becoming the story
For a century, Alzheimer’s research mostly asked what piles up in the brain. Some of the most exciting work now asks the reverse: how the brain takes out its own trash.

A blood-test “clock” estimates when Alzheimer’s symptoms will start
p‑tau217 is a protein in the blood that reflects Alzheimer’s changes in the brain. A WashU Medicine team built models that turn one p‑tau217 measurement into an estimated time until symptoms, and in two groups of research volunteers the estimates were typically off by 3 to 4 years. Age set the pace: crossing the test’s threshold at 60 came with about 20 years of warning, at 80 about 11. Where it stands: a research tool for choosing prevention-trial volunteers. Not yet precise enough for one person’s forecast.

A cheap seizure drug kept neurons from making the stickiest amyloid, in mice and human cells
Levetiracetam is an inexpensive prescription drug for seizures. A Northwestern team found it slows how neurons recycle parts of themselves, steering them away from making amyloid-beta 42, the form that clumps into plaques. It worked in mice and in human cells, and the researchers say it would have to start years before symptoms. Where it stands: lab and mouse work. Not a reason to start or stop the drug.

A lifetime of reading and learning came with a later Alzheimer’s diagnosis
Rush University followed 1,939 older adults and scored their “lifetime enrichment”: books at home as a child, a library card in midlife, puzzles and games later on. The top tenth were diagnosed with Alzheimer’s at 94 on average, against 88 for the bottom tenth. Their donated brains didn’t have fewer plaques and tangles, but their thinking held up better near the end of life. Where it stands: an association, partly based on childhood memories recalled decades later.
