This chart shows human brains size over time. They got way bigger, fast. But now they’re shrinking? (No, it’s not the phones!) About 2 million years ago something changed and it altered the course of human evolution. Our brains just started RAPIDLY growing, the organ nearly doubled in size in just a few hundred thousand years. This turning point is what allowed us to evolve into the intelligent species we are today. But now… To learn more, follow along! #evolution #human origins #science

Alzheimer’s disease is often thought of as something that happens later in life, but research suggests the underlying changes in the brain can begin decades before symptoms appear—sometimes as early as your 30s and 40s. During this silent phase, processes like inflammation, insulin resistance in the brain, and buildup of abnormal proteins may gradually develop long before memory loss becomes noticeable. The encouraging news is that there is a lot you can do today to support long-term brain healt
