How Brain Inflammation Drives Depression, Alzheimer's, and Parkinson's

For decades, we've thought about conditions like Alzheimer's disease, depression, and Parkinson's disease as disorders of the brain. But what if that's only part of the story? Emerging science is revealing that many of the factors driving cognitive decline, mental illness, and neurodegenerative disease may begin far outside the brain itself—in our metabolism, our immune system, our gut microbiome, our hormones, and even the environment we're exposed to every day. As part of our summer series, we're revisiting some of the most important conversations we've had on the topic of brain health. In this special compilation episode, you'll hear from leading experts Dr. Richard Isaacson, Dr. Chris Palmer, and Drs. Ray Dorsey and Michael Okun as they explore the new science of brain health and what it means for preventing cognitive decline, supporting mental health, and protecting our brains as we age. What I find most encouraging about this research is that it challenges the idea that brain decline is simply an inevitable part of aging. Instead, it suggests that many of the biggest drivers of brain health are things we can influence through the choices we make, the environments we create, and the ways we care for our bodies long before symptoms ever appear.
