Head Impact MEG Changes Mapped to Neurochemical Brain Systems

TL;DR: A 2026 preprint in medRxiv found that head-impact-related magnetoencephalography (MEG) changes in high-school football players were strongest in cortical regions matching specific neurotransmitter and gene-expression maps, especially norepinephrine, nicotinic acetylcholine, APOE, and BDNF-related patterns. Key Findings MEG tracked pre-to-post-season brain signaling across 278 timepoints from 91 male high-school football players. Concussion-related cortical slowing aligned …

EPA Rewired Brain Vessels After Repetitive Brain Injury

EPA Rewired Brain Vessels After Repetitive Brain Injury TL;DR: Fish-oil-derived EPA looked less like a simple neuroprotective supplement and more like a lipid signal that changed brain-vessel repair after repetitive mild traumatic brain injury. Key Findings EPA accumulated before injury: In a fish-oil diet model, eicosapentaenoic acid built up in the brain at baseline rather …

Endless Echoes: Concussions Ignite Chronic Brain Inflammation in Athletes

by

Researchers have found signs of ongoing inflammation in the brains of athletes still experiencing concussion symptoms months or years after their injury, according to a new study published in Journal of Neuroinflammation. The findings suggest the concussion triggered chronic neuroinflammation that may be contributing to their persistent symptoms. Key Facts: The study examined athletes who …
