This Is What Exercise Actually Does to Your Brain

Most people think a brain scan is just a snapshot of what is wrong right now. Dr. Mistry has spent twenty years reading over 300,000 neuroimaging studies and what he has found is that your brain scan does not just show you the present. It reveals your past and with the right tools, it predicts your future. In this episode, I sit down with Dr. Mistry, a neuroradiologist and neuroimaging specialist, to break down exactly how AI is transforming what we can detect in the brain and why the window to intervene is decades earlier than anyone tells you. We cover the F1 car analogy that reframes every component of your central nervous system, why Alzheimer's disease begins twenty to thirty years before diagnosis, and how a volumetric MRI spotted a 2.2% hippocampal volume loss in a woman in her 50s that the human eye could not detect on two consecutive normal scans. This episode will change how you think about your brain scans, your cardiovascular health, and the daily decisions that are either protecting or silently degrading your most important organ.
