Two Opposing Brain Fuel Patterns May Predict Who Keeps Their Cognition With Age
Brain white matter (the wiring that connects brain regions) uses glucose differently depending on where you look. In over 3,000 participants across two studies, higher glucose use in expected areas like the corpus callosum linked to better thinking skills. But higher glucose use in unusual areas like the corona radiata linked to worse cognition, likely a sign the brain is compensating. Over time, people with strong "normal" metabolism and low "compensatory" metabolism declined more slowly.
Key Insight
This study suggests white matter glucose patterns could help identify people at risk for cognitive decline earlier.

Mediterranean and MIND Diets Linked to Lower Dementia Risk in Korean Adults
In a 20-year study of over 5,000 Korean adults, those who stuck closest to the Mediterranean, MIND, or Korean Healthy Eating diets had about 20% lower odds of developing high dementia risk scores. Meanwhile, people eating the most inflammatory foods saw their risk climb. The takeaway lines up with what we already suspect about brain-friendly eating, but it's the first solid evidence in a Korean population.
Why Alzheimer's May Look Like a Viral Infection That Isn't There
This review proposes that Alzheimer's behaves like the brain fighting a fake viral infection. Old retrotransposons and leaked mitochondrial DNA trick immune cells into thinking there's a virus, triggering chronic inflammation and turning brain support cells into zombie-like senescent cells. The authors suggest that HIV drugs (NRTIs) and senolytics could one day target this hidden cascade. It's a fresh angle after years of failed amyloid-focused drugs.
Inflammation in the Blood Shows Up as Damage in Brain Wiring
In late middle-aged and older adults, higher levels of inflammatory markers in blood were tied to subtle changes in white matter, the brain's wiring. People with more pro-inflammatory cytokines and CRP showed signs of disrupted neural fibers. The link held even after accounting for Alzheimer's biomarkers. This supports the idea that chronic inflammation quietly chips away at brain health.
