Community Gatherings Halve Cognitive Disability Risk in Non-Exercising Older Adults
A four-year study found that older adults who don't exercise but attend community gatherings have half the risk of cognitive disability. The benefit was not seen in those who already exercise regularly.
Obesity-Linked Fat Molecules May Trigger Alzheimer's Brain Changes
Obesity raises fat molecules that travel to the brain, disrupting immunity and promoting amyloid buildup. Correcting this imbalance improved memory in Alzheimer's models.
Sleep and Genetics: Why Poor Sleep Hits Some Brains Harder
New research shows that a gene involved in the brain's overnight cleaning system can determine how strongly poor sleep affects Alzheimer's-related brain changes, pointing to personalized prevention.
How Ketamine and Psychedelics Rewire Immune Signals to Relieve Depression
A new study shows that rapid-acting antidepressants like ketamine and psychedelics share a common neuroimmune pathway, which could help predict who responds to treatment.
AI Speech Analysis Predicts Teen Mental Health Risks
NLP models analyzing children's speech style at ages 9-13 predict future mental health disorders six years later better than human experts.
Mitochondrial Plaques: New Alzheimer's Target Found
Researchers discover mitochondrial plaques, intracellular amyloid deposits that form early in Alzheimer's, offering a new therapeutic target.
AI in Deep Brain Stimulation: Progress but Limited Readiness
A systematic review of 239 studies finds AI for deep brain stimulation is promising but mostly premature, with external validation rare.
Bidirectional Information Flow Predicts Navigation Efficiency Across Species
A new framework uses transfer entropy to measure sensory-behavior feedback, predicting navigation efficiency in bacteria, worms, flies, and AI agents.
Sleep Brain Waves Can Predict Dementia Years Early
Machine learning uses sleep EEG to estimate brain age. Older brain age linked to higher dementia risk, offering early detection.
Large Language Models and Human Cognition: Deep Similarities
New research from arXiv reveals that LLMs and human brains share five core organizational principles, challenging the view that they are alien intelligences.
Why Vivid Dreams Leave You Feeling Exhausted
New research finds that during REM sleep, brain blood flow and fuel rise, but neuronal ATP drops, explaining the tiredness after vivid dreams.
Gut-Brain Link Helps Form Food Memories, Junk Food Weakens It
Signals from the gut to the brain help turn meals into lasting memories, but diets high in fat and sugar may weaken this system over time, according to a new study in rats.
