Experts Urge G20 to Make Alzheimer's a Priority
Leaders say changes in the brain begin decades before symptoms, so early action on dementia matters.

Should the government spend more money on preventing Alzheimer's disease?
Former ministers and global health leaders published a Global Communiqué on November 5, 2026, calling on the G20 to make Alzheimer's disease a priority. The communiqué also calls for a permanent mechanism to sustain political commitment to brain health, and it is open to further signatories.
Why it matters
Alzheimer's biology begins developing ten to twenty years before symptoms appear, which is why the signatories argue prevention and early action deserve sustained high-level attention rather than episodic campaigns. The appeal to the G20 signals a push to treat brain health as a standing global policy issue.
The communiqué draws on the established finding that Alzheimer's biological changes precede symptoms by a decade or more, and on estimates that nearly half of dementia cases could be prevented or delayed by modifying risk factors over a lifetime. Blood tests can increasingly detect these early biological markers, and trials are testing whether intervening before symptoms appear can halt the disease.
The players
Dr Nora Berra
Former Minister for Seniors and former Minister of Health of France, who initiated the Global Communiqué on brain health.
The details
Alzheimer's disease is detectable in the body long before memory loss becomes noticeable, because the underlying biological changes accumulate silently for years. Blood tests are increasingly able to pick up these biological markers, which is what makes earlier identification possible in principle. Clinical trials are now testing whether treating the disease before symptoms emerge can stop it from taking hold, a shift from treating established symptoms.
Timeline
Biological changes of Alzheimer's begin ten to twenty years before the first symptoms appear.
The Global Communiqué calling on G20 action was published on November 5, 2026.
Health Landscape
The push places Alzheimer's within the G20's global health agenda, asking leaders to treat brain health as a sustained policy priority. The shift toward pre-symptomatic detection and intervention marks a move away from managing the disease only after memory problems appear.
Because the biology of Alzheimer's develops well before symptoms, it is worth raising brain health with your physician as a long-term concern rather than only when memory changes appear. Lifestyle factors that influence risk over a lifetime are the area where this communiqué suggests individuals and health systems can have the most influence.
The takeaway
Alzheimer's changes begin a decade or more before symptoms, so early attention matters. Ask your doctor about brain health and which risk factors you can influence over your lifetime.
