WHO Flags Air Pollution in Dementia Plan as 57 Million Cases Rise

Summary
WHO’s updated dementia-prevention guidance adds air pollution as a major modifiable risk factor and says governments—not just individuals—must act to cut exposure and reorganize care.
99% of the global population is exposed to polluted air, WHO said, and eliminating that exposure could prevent about 3% of dementia cases because fine particles can cross into the brain and drive inflammation.
Up to 45% of dementia risk is tied to modifiable factors, the agency said, while hearing-loss treatment could avert 7% of cases and vision-loss prevention 2%; obesity affects 16% of the world’s population.
The guidance still backs exercise, social engagement and brain-stimulating activities, but shifts away from generic supplements toward Mediterranean or DASH-style diets and broader multidomain interventions, especially for people with mild cognitive impairment.
