Picture this: your brain is a high-performance engine. Over decades, it doesn’t just wear down, it also starts to run hot.
Tiny “fires” of inflammation smolder deep within the brain’s memory center, creating a persistent brain fog that makes it harder to think, form new memories or even adapt to new environments, all the while increasing the risk to disorders like Alzheimer’s disease.
Scientists call this slow burn “neuroinflammaging , ” and for decades it was thought to be the inevitable price of growing older.
