Most people think Alzheimer's is genetic. But the research tells a different story.
The air you breathe every day may be quietly increasing your risk — and most doctors never mention it.
PM2.5 particles from air pollution are small enough to enter your bloodstream, cross into the brain, and activate the same inflammatory cascade we see driving cognitive decline and Alzheimer's disease.
Combined with a diet high in processed foods and refined sugar? You are giving neuroinflammation exactly what it needs to take hold.
The good news: these are modifiable risks and the solution is practically free.
In Episode 61 of Alzheimer's Breakthrough, I sat down with Dr. Austin Perlmutter — physician, researcher, and NYT bestselling author — to break down what actually moves the needle on Alzheimer's prevention. Diet, air quality, polyphenols, nature exposure, and why prevention has to start decades before symptoms appear.
