Dementia: What can be slowed, better managed, and even reversed?

For many people, dementia is more frightening than cancer. The fear of forgetting loved ones, the stigma, the sense that you're losing yourself — it's enough to make people avoid a diagnosis altogether. But Brightly's lead geriatrician Dr. Cheryl Johnson says delay is the worst choice you can make, because the earlier you act, the more options you have. In this episode, Hannah McQueen sits down with Dr. Cheryl to unpack what dementia actually is, and why so much of what we assume about it is wrong. They cover the difference between normal brain aging and the kind of forgetfulness worth taking seriously, how to tell mild cognitive impairment from dementia, and why a diagnosis can take three and a half years in New Zealand when it shouldn't. Dr. Cheryl breaks down the umbrella of dementia — Alzheimer's, vascular, Lewy body and the rest — and explains which types respond to medication, how well those drugs work, and the side effects worth watching for. She also shares what has her genuinely excited: new anti-amyloid treatments like lecanemab that could change the game, but only if people are picked up early enough to benefit. Crucially, this isn't a conversation without hope. Hannah and Dr. Cheryl walk through what you can do right now to protect your brain — exercise, diet, sleep, hearing checks, managing blood pressure and cholesterol — and the surprising number of conditions (like B12 deficiency and thyroid problems) that can look like dementia but are reversible. They also talk honestly about the toll on carers, the challenge of patients who lack insight, and why walking alongside families matters as much as the diagnosis itself. The message is simple: knowing early is powerful, even when the news isn't what you hoped to hear.
