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 ...
Drugs designed to clear amyloid beta from the brain—once seen as a promising path to slowing Alzheimer’s—may not actually help patients in any meaningful way, according to a major review of over 20,000 participants. Even more concerning, they ...
Scientists have discovered a way to help the brain clean itself of harmful Alzheimer’s plaques by activating its own support cells. By increasing a protein called Sox9, researchers were able to boost the activity of astrocytes, star shaped cells ...
Scientists have uncovered a surprising link between simple body movement and brain health: every time you tighten your abdominal muscles—even slightly—your brain may gently sway inside your ...
Researchers have identified a new potential weapon against Alzheimer’s: blocking a protein called PTP1B. In mice, this approach boosted memory and helped brain immune cells clear harmful plaque buildup. Since PTP1B is also linked to diabetes and ...
A rare group of adults over 80, known as SuperAgers, are rewriting what we thought was possible for the aging brain. With memory abilities comparable to people decades younger, their brains either resist or withstand the damage typically linked to ...
Loneliness may quietly affect how well older adults remember things—but it might not be speeding up mental decline after all. A large European study tracking over 10,000 people for seven years found that those who felt lonelier started off with ...
Alzheimer’s isn’t just one problem—it’s a tangled mix of biology, aging, and overall health. That’s why drugs targeting a single factor have fallen short, even as new treatments show modest benefits. Scientists are now pushing toward ...
Scientists have uncovered a surprising new player in Alzheimer’s disease: a protein called CSE that helps produce tiny amounts of hydrogen sulfide gas in the brain. In experiments with genetically ...
Scientists at Oregon State University have captured something researchers have long struggled to see: the real-time chemical interactions that help drive Alzheimer’s disease. By watching how metal ions—especially copper—trigger harmful protein ...
Scientists have uncovered how your body actually tells your brain to stop eating when you’re sick. In a new study, researchers found that specialized cells in the gut detect parasites and send ...
Scientists have uncovered a hidden “death switch” in the brain that may be driving Alzheimer’s disease—and even found a way to turn it off in mice. The culprit is a toxic pairing of two proteins that, when combined, triggers the destruction ...

Earlier Headlines

 

When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like mice, this replay still occurs — but the signals are jumbled and poorly ...

A new brain imaging study reveals that remembering facts and recalling life events activate nearly identical brain networks. Researchers expected clear differences but instead found strong overlap ...

A new genetic study suggests that obesity and high blood pressure may play a direct role in causing dementia, not just increasing the risk. By analyzing data from large populations in Denmark and the ...

Cannabis-based medicines have been widely promoted as a potential answer for people living with chronic nerve pain—but a major new review finds the evidence just isn’t there yet. After analyzing ...

A massive international brain study has revealed that memory decline with age isn’t driven by a single brain region or gene, but by widespread structural changes across the brain that build up over ...

Alzheimer’s may be driven far more by genetics than previously thought, with one gene playing an outsized role. Researchers found that up to nine in ten cases could be linked to the APOE gene — ...

Researchers have identified OTULIN, an immune-regulating enzyme, as a key trigger of tau buildup in the brain. When OTULIN was disabled, tau vanished from neurons and brain cells remained healthy. ...

Your daily rhythm may matter more for brain health than previously thought. Older adults with weaker, more disrupted activity patterns were far more likely to develop dementia than those with steady ...

Cannabis products with higher THC levels may slightly reduce chronic pain, particularly nerve pain, according to a review of multiple clinical trials. The improvement was small and short-lived, while ...

New research suggests Alzheimer’s may start far earlier than previously thought, driven by a hidden toxic protein in the brain. Scientists found that an experimental drug, NU-9, blocks this early ...

Eating full-fat cheese and cream may be associated with a lower risk of dementia, according to a large study that tracked people for more than 25 years. Those who consumed higher amounts of these ...

Researchers discovered that a tiny structural feature of the enzyme GPX4 helps keep neurons safe. A rare mutation removes this protection, allowing harmful molecules to damage cell membranes and ...

Obesity accelerates the rise of Alzheimer’s-related blood biomarkers far more rapidly than previously recognized. Long-term imaging and plasma data show that obese individuals experience much ...

A unique vaccine rollout in Wales gave researchers an accidental natural experiment that revealed a striking reduction in dementia among seniors who received the shingles vaccine. The protective ...

Scientists have uncovered a stepwise system that guides how the brain sorts and stabilizes lasting memories. By tracking brain activity during virtual reality learning tasks, researchers identified ...

Scientists studying young adults with obesity discovered early indicators of brain stress that resemble patterns seen in cognitive impairment. The group showed higher inflammation, signs of liver ...

Spermine, a small but powerful molecule in the body, helps neutralize harmful protein accumulations linked to Alzheimer’s and Parkinson’s. It encourages these misfolded proteins to gather into ...

Researchers discovered that raising the protein Sox9 can help the brain’s astrocytes clear out toxic plaque buildup linked to Alzheimer’s. In mouse models that already showed memory problems, ...

Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered ...

Researchers discovered that clogged brain “drains” show up early in people at risk of Alzheimer’s disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup ...
