Menopause brings profound shifts not just in hormones but in the very structure of the brain. Scientists have found that gray matter in regions tied to memory and thinking can shrink, while white matter may show damage linked to blood flow issues. ...
A major collaboration between UC San Diego and 23andMe identified genes that shape cannabis use behaviors. The study linked the CADM2 and GRM3 genes to cannabis use and connected these patterns to more than 100 traits across mental and physical ...
SuperAgers defy normal aging by keeping sharp memories and healthy brains well into their 80s. Northwestern scientists discovered that these individuals either resist the buildup of harmful brain ...
A long-term Australian study found that calcium supplements do not raise dementia risk in older women, countering previous fears. The research followed more than 1,400 participants for nearly 15 years and revealed no harmful cognitive effects. ...
Long before humans built cities or wrote words, our ancestors may have faced a hidden threat that shaped who we became. Scientists studying ancient teeth found that early humans, great apes, and even Neanderthals were exposed to lead millions of ...
Johns Hopkins scientists uncovered microscopic “nanotube” channels that neurons use to transfer toxic molecules. While this process clears waste, it can also spread harmful proteins like amyloid-beta. Alzheimer’s-model mice showed more ...
Researchers have synthesized enhanced vitamin K analogues that outperform natural vitamin K in promoting neuron growth. The new compounds, which combine vitamin K with retinoic acid, activate the mGluR1 receptor to drive neurogenesis. They also ...
Researchers at USC have created the first method to noninvasively measure microscopic blood vessel pulses in the human brain. Using advanced 7T MRI, they found these tiny pulsations grow stronger with age and vascular risk, disrupting the brain’s ...
Groundbreaking Harvard research is exposing hidden energy failures inside brain cells that may drive major psychiatric conditions. By studying reprogrammed neurons, scientists are revealing how cellular metabolism shapes mood, thought, and ...
UMass Amherst engineers have built an artificial neuron powered by bacterial protein nanowires that functions like a real one, but at extremely low voltage. This allows for seamless communication with biological cells and drastically improved energy ...
Finasteride, a common hair-loss drug, has long been tied to depression and suicide, but regulators ignored the warnings. Prof. Mayer Brezis’s review exposes global data showing psychiatric harm and a pattern of inaction by Merck and the FDA. ...
People experiencing their first psychotic episode who also have skin conditions such as rashes or itching are at greater risk of depression and suicidal thoughts, according to new research presented at the ECNP meeting. Scientists found that 25% of ...

A new study shows glioblastoma isn’t confined to the brain—it erodes the skull and hijacks the immune system within skull marrow. The cancer opens channels that let inflammatory cells enter the ...

Stanford scientists found that aging disrupts the brain’s internal navigation system in mice, mirroring spatial memory decline in humans. Older mice struggled to recall familiar locations, while a ...

Researchers uncovered a key cellular regulator, PP2A-B55alpha, that controls both the cleanup of damaged mitochondria and the creation of new ones. In Parkinson’s disease models, reducing this ...

New research from Houston Methodist reveals how obesity may directly drive Alzheimer’s disease. Scientists discovered that tiny messengers released by fat tissue, called extracellular vesicles, can ...

Penn researchers found that psilocybin can calm brain circuits tied to pain and mood, easing both physical suffering and emotional distress in animal studies. The compound works in the anterior ...

Researchers have designed a peptide that prevents the deadly misfolding of alpha-synuclein, the protein behind Parkinson’s and some dementias. In lab and animal tests, it stabilized the protein and ...

A massive nationwide study has linked long-term exposure to the industrial chemical trichloroethylene (TCE) with a higher risk of Parkinson’s disease in older adults. Researchers examined over 1.1 ...

Researchers in Japan have pinpointed a biological cause of Long COVID brain fog using advanced PET brain imaging. They discovered widespread increases in AMPA receptor density linked to cognitive ...

New research shows that poor sleep could make the brain appear years older than it really is. Using MRI scans and machine learning, scientists found a clear link between unhealthy sleep patterns and ...

Researchers found that middle-aged adults, especially women, are far more likely to be addicted to ultra-processed foods than older generations. Marketing of diet-focused processed foods in the 1980s ...

Scientists have discovered that DMT, a natural compound found in plants and even the human brain, can dramatically reduce brain damage caused by stroke. The psychoactive molecule, long known for its ...

Scientists have discovered a way to block pain while still allowing the body’s natural healing to take place. Current painkillers like ibuprofen and aspirin often come with harmful side effects ...

A University of Toronto study found that nearly one in four adults aged 60+ who reported poor well-being were able to regain optimal wellness within three years. The research highlights that physical ...

Boston University researchers found that ordinary moments can gain staying power if they’re connected to significant emotional events. Using studies with hundreds of participants, they showed that ...

New studies show that a bacterial molecule, peptidoglycan, is present in the brain and fluctuates with sleep patterns. This challenges the idea that sleep is solely brain-driven, instead suggesting ...

A massive new study combining observational and genetic data overturns the long-held belief that light drinking protects the brain. Researchers found that dementia risk rises in direct proportion to ...

A University of New Mexico scientist is revealing what might be one of the most overlooked causes of dementia — damage in the brain’s tiny blood vessels. Dr. Elaine Bearer has created a new way ...

Researchers in Japan discovered that Parkinson’s patients diagnosed in their 80s are far more likely to show signs of amyloid buildup, a hallmark of Alzheimer’s, even without dementia symptoms. ...

For decades, scientists believed Alzheimer’s was driven mainly by sticky protein plaques and tangles in the brain. Now Purdue researchers have revealed a hidden culprit: fat. They found that brain ...

New studies reveal that lifestyle changes—such as exercise, healthy eating, and social engagement—can help slow or prevent cognitive decline. Experts say this low-cost, powerful approach could ...
