Episode 12: Dementia Is Not Inevitable

Dementia is often seen as an inevitable part of ageing — but the reality is far more hopeful. Many of the risk factors are within our control. In this episode of Live Longer Better, Leslie Kenny and Professor Sir Muir Gray explore why up to 90% of dementia risk is modifiable, and what that means in practical terms. From protecting the brain itself to maintaining blood flow and staying socially engaged, they break down the key drivers of brain health. ______________________________________________________________ This conversation reframes dementia, highlighting that it is not a single disease but a group of conditions — and that the same actions that reduce risk can also help slow its progression. ______________________________________________________________ 🔑 Core Message Dementia is not inevitable. By protecting brain health, supporting blood flow, and staying mentally and socially active, you can significantly reduce your risk and improve long-term cognitive resilience. ______________________________________________________________ 🎧 What You’ll Learn • Why dementia is not one disease, but many different conditions • What “modifiable risk” means and how much control we really have • The difference between Alzheimer’s and vascular dementia • How lifestyle and environment influence brain health • The role of genes like APOE4 — and why they’re not the full story • Why social isolation and lack of stimulation increase dementia risk ______________________________________________________________ 🛠️ Actionable Longevity Tips • Protect your brain: prioritise sleep, manage stress, and avoid head injury • Support blood flow: stay active, eat well, and avoid smoking • Reduce exposure to air pollution where possible • Stay mentally challenged through learning and new experiences • Maintain strong social connections and avoid isolation • Treat brain health as something to actively manage, not passively accept ______________________________________________________________ 🌍 About the Oxford Longevity Project The Oxford Longevity Project (OLP) is a community interest company dedicated to translating the latest research in healthy ageing, longevity science, and healthspan optimisation into practical action. ______________________________________________________________ 🌐 Follow Oxford Longevity Project • YouTube: @OxLongevity Instagram: @oxfordlongevityproject LinkedIn:   / oxford-longevity-project   Website: oxfordlongevityproject.org Newsletter: https://tinyurl.com/olpnewsletter ______________________________________________________________ 🤝 Sponsored by Oxford Healthspan Supporting evidence-based approaches to healthy ageing and longevity.
