Scientists Found Something Strange About Lithium in Nearly 400 Human Brains
There is lithium in your brain right now. You cannot see it, feel it, or measure it on a kitchen scale, but Harvard researchers spent roughly a decade searching for tiny traces of it in nearly 400 donated human brains. When they compared people who died with their memory intact against those with mild cognitive…
Scientists Followed Nearly 4,000 People For 3 Years And Their Brains Kept Improving
Imagine reaching your 80s or even your 90s and being told that your brain could still improve. That possibility is attracting attention after researchers followed 3,966 adults between the ages of 19 and 94 for three years, measuring their brain health every six months. The results did not show a simple pattern of older people…
New Alzheimer’s Drug Is Being Tested to See If It Can Prevent Dementia Early
You feel fine. Your memory is sharp. You can recall names, appointments, the thread of a conversation without effort. And yet a simple blood test has flagged something moving quietly in your brain, years before it would ever announce itself, and doctors want to intervene now, while nothing appears to be wrong at all. That…
Should There Be an Age Limit on the U.S. Presidency? Thousands of People Just Weighed In
At some point over the last several years, a question that once felt hypothetical became unavoidable. Two consecutive U.S. presidents were the oldest ever to hold the office. Both had their mental sharpness questioned publicly while in power. Both were well past the age at which most Americans leave the workforce. And yet both were…
Gen Z Scored Lower Than Millennials on Every Cognitive Measure, and a Neuroscientist Just Told Congress Why
For more than two centuries, a quiet pattern held steady across the developed world. Each generation of children grew up to be a little sharper, a little more capable, a little better equipped for the cognitive demands of modern life than the generation before them. It was one of the most reliable trends in recorded…
New Study Finds Eating More Than 1 Egg Per Week Cuts Alzheimer’s Risk by 47%
Breakfast tables hold a simple secret that might protect aging brains. Scientists spent nearly seven years tracking over 1,000 older adults, recording what they ate and watching who developed dementia. Results revealed something remarkable about a common food most people already keep in their refrigerators. One egg per week. Such a small dietary change. Yet…
Researchers Discover Brain Cell Protein That Reverses Memory Decline Without Removing Alzheimer’s Plaques
What if we’ve been chasing the wrong villain in the story of Alzheimer’s? For decades, scientists have zeroed in on the dark buildup of beta-amyloid plaques those sticky protein clumps that gather in the brain as the prime suspect behind memory loss and cognitive decline. Billions have been poured into therapies designed to clear them…
