Brain Fog After 40: The Hormone, Sleep, and Stress Connection No One Explains
If you’ve started forgetting words, losing your train of thought, or feeling mentally slower after 40, you’re not imagining it—and you’re not alone.
In this episode, Dr. Jill and Dr. Ade explain why brain fog is so common in midlife, how hormonal shifts in perimenopause affect cognition, and why stress and disrupted sleep can make mental clarity feel out of reach. They break down what’s happening in the brain, what’s within the range of normal midlife change, what deserves further evaluation, and what actually helps restore focus and confidence.
This is a grounded, science-based conversation for women who are worried about their brain—but tired of being told it’s “just stress” or “normal aging.”
