New research reveals that intelligence plays a key role in how well people process speech in noisy environments. The study compared neurotypical and neurodivergent individuals and found that cognitive ability predicted performance across all groups. ...
Generalized anxiety disorder affects millions, often trapping sufferers in cycles of fear and isolation that conventional medications barely relieve. At UCSF, neuroscientist Jennifer Mitchell is testing a pharmaceutical form of LSD called MM120, ...
GLP-1 drugs, originally developed for diabetes and obesity, may also curb addictive behaviors by acting on reward circuits in the brain. Early trials show reductions in alcohol intake, opioid seeking, and nicotine use. Though more research is ...
A new study shows that eating more fruits and vegetables during the day can significantly improve sleep that same night. Researchers found a clear link between diet quality and sleep depth, with participants who met the CDC’s daily produce ...
Researchers found that neurons can use fat, not just sugar, to power the brain. When a protein called DDHD2 fails, this process breaks down and leads to serious brain problems. Scientists were able to restore damaged cells by feeding them fatty ...
Inside your body, an intricate communication network constantly monitors breathing, heart rate, digestion, and immune function — a hidden “sixth sense” called interoception. Now, Nobel laureate ...
A massive genetic study found that naturally lower cholesterol is linked to a dramatically reduced risk of dementia. The research simulated the effects of cholesterol-lowering drugs and showed up to an 80% lower risk for certain genetic profiles. ...
Researchers have finally seen and measured the tiny alpha-synuclein oligomers that may ignite Parkinson’s disease. With the ultra-sensitive ASA-PD imaging method, they captured these clusters in brain tissue, finding larger and more numerous ...
Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier brain structures. The cells seemed to protect ...
Scientists have uncovered a toxic alliance between Aβ and fibrinogen that may explain how Alzheimer’s disease begins. The two proteins together create stubborn clots that damage blood vessels and spark inflammation in the brain. These effects ...
New research reveals that exercise counteracts the mood-damaging effects of a Western-style diet through specific gut and hormonal mechanisms. Running restored metabolites tied to mental well-being and balanced key hormones like insulin and leptin. ...
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. ...

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 ...

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 ...

Different types of depression affect the body in different ways. Atypical, energy-related depression raises the risk of diabetes, while melancholic depression increases the likelihood of heart ...

Researchers have discovered that ADHD’s hallmark mind wandering might actually boost creativity. People who deliberately let their thoughts drift scored higher on creative tests in two large ...

Researchers have identified two compounds, K102 and K110, that could repair the nerve damage from multiple sclerosis. These drugs help regenerate the protective myelin sheath and balance immune ...

Scientists have pinpointed Y1 receptor neurons in the brain that can override chronic pain signals when survival instincts like hunger or fear take precedence. Acting like a neural switchboard, these ...

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 ...

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 ...

Dolphins washing up on Florida’s shores may be victims of the same kind of brain degeneration seen in humans with Alzheimer’s disease. Researchers discovered that cyanobacterial toxins—worsened ...

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 ...

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 ...

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 ...
