Lancet study finds 45% of dementia cases could be prevented despite diagnosis delays

A Lancet study suggests as many as 45% of dementia cases could be prevented or delayed through modifiable risk factors such as smoking, diet, exercise, hearing/vision care, and social engagement, reinforcing the idea that heart and brain health are tightly linked. Meanwhile, reports from the UK highlight long delays in dementia diagnosis and the strain on families, even as a Phase III trial explores biomarker-based prevention before symptoms appear, underscoring the need for scalable diagnostic infrastructure and timely support.
