Nearly Half of Dementia Cases Could Be Prevented, But Action is Needed

A major international review from Curtin University published in The Lancet Healthy Longevity reveals that almost 50% of dementia cases could be prevented by addressing modifiable risk factors including physical inactivity, smoking, low education levels, and social isolation. However, the research indicates that current public health campaigns, while reaching large audiences, often fail to drive meaningful behavioral change and produce only modest improvements in awareness. The study highlights a critical gap between knowledge and action in dementia prevention strategies. Healthcare experts emphasize that more targeted, personalized interventions are necessary to help people implement lasting lifestyle modifications that reduce dementia risk.
