Alzheimer’s doesn’t begin at diagnosis—it starts decades earlier. That means the choices we make right now can have a major impact on our brain health down the line. But with so much conflicting health advice out there, how do you know what really moves the needle? Today’s guest cuts through the noise and shares the most effective, science-backed strategies to protect your brain, no matter your age.
