Depression and brain fog often show up together, and when they do, daily life can feel heavier than it should. In the U.S., about 21 million adults—roughly 8% of the population—experience at least one major depressive episode each year. Many of them also notice their thinking becoming unclear, scattered, or slower than usual. Tasks that once felt simple suddenly require more energy, and decisions take longer than they should.
You may even wonder why your mind doesn’t “work” the way it used to. But you’re not alone, and you’re not imagining it. There’s a real, physical connection between depression and the brain.
