New research indicates that dreaming during REM sleep may consume significant brain energy, with neuronal energy levels dropping despite an increase in the brain's fuel supply.
Caffeine can reduce the restorative quality of sleep by decreasing slow-wave brain activity, even if it doesn't prevent someone from falling asleep or staying asleep for a full night.
A new study reveals that the 3D organization of DNA is disrupted in brain cells affected by Alzheimer's disease, altering gene activity.
A study found that using a HEPA air purifier for one month improved brain function by 12% in adults aged 40 and older, suggesting a link between cleaner air and cognitive health.
New research reveals that schizophrenia is linked to a widespread, organized loss of brain synapses, particularly in the left hemisphere, following the brain's unique molecular and connectivity architecture.
A stress hormone called CRH may help the brain repair itself after injury and influence normal brain development by regulating myelin-producing cells.
Scientists have identified a biological tipping point in microglial behavior that may determine whether Alzheimer's pathology leads to dementia, offering new treatment targets.
A new study reveals that cancer-linked mutations found in immune cells may contribute to Alzheimer's disease, suggesting new diagnostic and treatment avenues.
Scientists at ETH Zurich identified a new Alzheimer's trigger and developed an experimental compound that slowed nerve cell loss and extended lifespan in mice.
Scientists have identified acetylcholine as a key brain chemical that helps individuals break bad habits and adapt to new situations, with implications for treating addiction and neurological disorders.
A study found that epigenetic changes at birth influence gut bacteria development, which is linked to early signs of autism and ADHD, with certain microbes potentially offering protection.
Scientists have discovered a molecular switch involving the STING protein that drives brain inflammation in Alzheimer's disease, offering a new target for treatments.
Researchers developed a nasal spray that reversed brain aging and improved memory in test models by reducing inflammation and restoring cellular energy.
A brain protein called Menin may drive aging and cognitive decline, and its restoration or a D-serine supplement reversed some effects in mice.
A UCSF study indicates that current vitamin B12 guidelines may not protect the aging brain, as lower active B12 levels are linked to cognitive issues and brain damage in older adults.
Scientists have identified the enzyme IDOL as a potential new target for Alzheimer's treatment, finding that its removal from neurons significantly reduced amyloid plaques and improved brain resilience in lab studies.
A study found that extended fasting causes significant biological changes in the human body, with major transformations occurring after about three days without food, affecting organs and protein activity.
A new study reveals that the amino acid arginine can significantly reduce toxic amyloid protein buildup and inflammation in animal models of Alzheimer's disease.
New research shows coffee, both caffeinated and decaffeinated, positively impacts the gut microbiome, mood, and cognitive functions.
Researchers discovered that boosting a protein called Sox9 helps the brain's astrocytes clear Alzheimer's plaques and preserve cognitive function in mice.
