3D Brain Models Outperform Network Models in Predicting Alzheimer's Progression
New mathematical models compare 3D brain geometries vs. brain connectome networks for predicting amyloid-beta and tau protein spread in Alzheimer's.
AI Study Links Appendix Removal and Diet to Higher Alzheimer's Risk
A massive AI analysis of nearly 10,000 people reveals that appendix removal and long-term dietary patterns are among the strongest predictors of Alzheimer's disease, shifting focus from brain to gut.
Rotten Egg Brain Gas Could Protect Against Alzheimer's
Johns Hopkins researchers found that a protein producing tiny amounts of hydrogen sulfide in the brain is essential for memory. Removing it in mice caused Alzheimer's-like damage.
Machine learning reveals brain signatures of motivation and ADHD
New research uses machine learning on EEG and MRI data to identify neural biomarkers for ADHD and individual differences in effort and reward sensitivity, highlighting fronto-parietal circuits.
Why Astronauts Over-Grip Objects in Space: The Brain's Gravity Memory
A 20-year study reveals astronauts' brains retain a 'memory' of Earth's gravity, causing them to over-grip objects in space—even after months of adaptation.
Hidden Brain Drain Pathway Discovered via Advanced MRI
Researchers using real-time MRI found a slow lymphatic-like fluid flow along the middle meningeal artery, revealing a previously unknown waste-removal hub in the human brain.
Loneliness Linked to Weaker Memory but Not Faster Decline
A large European study found that lonely older adults start with weaker memory, but their cognitive decline doesn't accelerate faster than socially connected peers.
Loss of Smell May Signal Early Alzheimer's, Study Finds
A declining sense of smell could be an early warning sign of Alzheimer's disease, appearing before memory problems. Research shows immune cells in the brain attack smell-related nerve fibers in early disease stages.
