From low-carb ice cream to keto protein bars to “sugar-free” soda, the decades-old sweetener erythritol is everywhere. But new University of Colorado Boulder research shows the popular sugar substitute and specialty food additive comes with serious downsides, impacting brain cells in numerous ways that can boost risk of stroke. The study was published in the Journal of Applied Physiology. “Our …

As the world continues to grapple with the rising tide of Alzheimer’s and age-related cognitive decline, researchers continue to explore everyday lifestyle choices and food items that can offer protection from this early cognitive decline, and among them is one surprisingly simple food item that is drawing attention from millions of people worldwide: An egg. A recent study published in …

Summary: Classical psychedelics like LSD, psilocybin, and mescaline are known for activating the 5-HT2A serotonin receptor, but a new study reveals their effects go far beyond. Researchers profiled 41 psychedelics against over 300 human receptors and found potent activity at serotonin, dopamine, and adrenergic sites. The study also showed that psychedelics activate multiple intracellular pathways, which may help separate their …

A widely-used sugar substitute found in products marketed to people with diabetes may involve more risks than rewards. In a new study published in the Journal of Applied Physiology, researchers from the University of Colorado Boulder found that erythritol — an organic compound used for so-called “stevia” products sold by the brands Wholesome, Truvia, and Splenda — can harm brain cells …

The hepatitis C virus (HCV) may play a role in mental health disorders such as schizophrenia, bipolar disorder, and major depression, according to a new study. Experts have long noted links between these psychiatric disorders and certain viral infections, but direct evidence of the viruses inside human brains is lacking. In the brain’s protective lining, however, the new study found …

“Hearst Magazines and Yahoo may earn commission or revenue on some items through these links.” Here’s what you’ll learn when you read this story: For more than a decade, there’s been growing proof that adult humans can form new neurons in the hippocampus, but scientists were still missing evidence of a missing link known as “neural progenitor cells.” Now, scientists …

Research indicates that prolonged sedentary behavior, even with regular exercise, elevates the risk of brain shrinkage and cognitive decline, particularly in older adults. The study, tracking participants over seven years, revealed a link between increased sitting time and neurodegenerative changes, irrespective of physical activity levels. Sitting is the new smoking. Prolonged sitting isn’t just bad for your heart; it could …

Summary: The anterior temporal lobe (ATL) plays a key role in interpreting social hierarchies and facial emotions, offering insight into anxiety and mood disorders. A research project used advanced imaging techniques to overcome past challenges in studying the ATL, revealing its strong activation during social and emotional decisions. Findings suggest anxiety disrupts the balance between semantic and emotional processing in …

TL;DR Gabapentin might raise dementia risk by ~30–40% in frequent or long-term users . Younger users (35–64) seem especially affected It’s not proof of cause—but strong enough to rethink long-term use. Other meds have similar risks—be informed across the board. Lifestyle is a powerful buffer—exercise, mindful diet, social engagement, mental stimulation. Chat with your doc, don’t self-diagnose or detox alone. …

Summary: New research has uncovered that neurons store their own glycogen, acting as “backup batteries” to keep the brain functioning during energy stress. Using worms and advanced biosensors, scientists found that neurons can tap into glycogen reserves, especially when oxygen or mitochondrial function is limited. This metabolic flexibility, termed “glycogen-dependent glycolytic plasticity,” shows neurons are more self-sufficient than previously believed. …
