Scientists discovered that high-fat junk food disrupts memory circuits in the brain almost immediately. Within just four days, neurons in the hippocampus became overactive, impairing memory. Restoring glucose calmed the neurons, showing that interventi…

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 the brain prioritizes fragile memories when they over…

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 transform dementia care and reduce its crushing toll on…

Scientists have uncovered how the brain reroutes its communication pathways depending on whether it’s processing something new or recalling the familiar. By fine-tuning the balance between different inhibitory circuits, the brain flexibly shifts betw…

Researchers from the University of Waterloo discovered that measuring long-term stress through children’s hair samples can reveal early signs of mental health risks in those living with chronic physical illnesses. Children with persistently high cort…

UC Berkeley researchers mapped the brain circuits that control growth hormone during sleep, uncovering a feedback system where sleep fuels hormone release, and the hormone regulates wakefulness. The discovery helps explain links between poor sleep, obe…

Scientists at Stanford have found that hyperactivity in the brain’s reticular thalamic nucleus may drive autism-like behaviors. In mouse models, drugs and neuromodulation techniques that suppressed this overactive region reversed symptoms, hinting at…

Getting a smartphone before age 13 may drastically increase the risk of poor mental health later in life, according to data from more than 100,000 people. Early use is linked to suicidal thoughts, aggression, and detachment, largely driven by social me…

Scientists at the University of Bath have developed a simple three-minute brainwave test called Fastball EEG that can detect memory problems years before Alzheimer’s is typically diagnosed. Unlike traditional memory tests, it passively records brain …

Virginia Tech researchers are investigating how overloaded mitochondria in the brain’s memory circuits may spark early Alzheimer’s damage. Their work focuses on calcium signaling and how it might trigger breakdowns in the entorhinal cortex.
