Brain aging seems gradual, but a critical phase accelerates deterioration sharply before stabilizing.

Brain Aging’s Critical Point<\/h2>\n\n\n\n

Researchers analyzed fMRI data from over 19,000 people<\/strong> tracking brain activity<\/a> changes. Results: brain aging ramps up ages 44-67<\/strong>, then steadies to ~90.<\/p>\n\n\n\n

Molecularly, key biomarkers\/gene expression point to neuronal insulin resistance<\/strong> driving accelerated phase\u2014brain struggles accessing energy pre-irreversible damage.<\/a>\u200b<\/p>\n\n\n\n
