Is Alzheimer's shifting from a disease we manage to one we can actually treat?
The World Alzheimer Report 2026, from Alzheimer's Disease International, says that after years of slow progress, we're now on the brink of real diagnostic and medical breakthroughs.
We're not talking about a cure — that's still a way off, and much of this is still in trials. But the shift in thinking is notable:
💊 New drugs already available overseas can slow progression in some people, by clearing the amyloid plaque that builds up years before symptoms appear
💉 Trials — some involving New Zealand — are testing whether treating people before symptoms appear could delay or prevent cognitive decline altogether
🩸 The report highlights emerging blood tests as a major development for detecting Alzheimer's earlier, with trials underway in the UK and Australia
🍅 Clinical trials also point to lifestyle changes — regular exercise, a Mediterranean-style diet, and staying socially connected — making a real difference to cognitive decline
Dr Campbell Le Heron, neurologist and Alzheimers NZ spokesperson, says these advances only matter if people can actually access them. He's calling for better diagnostic pathways, a stronger specialist workforce, more trained primary care clinicians, and investment in community-based dementia services — warning that Māori, Pacific peoples and rural communities shouldn't be left behind.
Hopeful news. But also a reminder that the system needs to be ready for it.
