The discussion also explores: Why dementia is increasingly common today The link between insulin resistance and brain health How loneliness and isolation increase dementia risk The powerful role of movement and muscle in protecting the brain The science behind BDNF - a key molecule that supports memory and cognition This is not just about living longer - it’s about staying sharp, connected, and mentally strong as we age.
