Young adults identified as key to global dementia prevention efforts

Published in The Lancet Healthy Longevity, the study shows that many risk factors for dementia, such as hearing loss, hypertension, and unhealthy lifestyle habits, are already prevalent in young adults, presenting a unique opportunity for early intervention.

The paper, led by the Next Generation Brain Health team, drew on experts from 15 countries to explore brain health promotion strategies in young adulthood. Findings support tailored research and policies that engage younger generations as partners in preventing dementia.

The authors recommend increasing public awareness of brain health through education in schools and tailored public health campaigns that empower young adults to make healthier choices. They also call for greater attention to sex and gender-specific factors, such as the impact of intimate partner violence and hormonal health, which can disproportionately affect brain health outcomes in women.

Recognising global inequalities, the authors stress the need for targeted efforts in low and middle-income countries and minority communities, where exposure to risk factors such as air pollution, limited education, and poor healthcare access is particularly high. The study urges national governments to introduce brain health charters with clear timelines, and financial commitments, alongside the creation of young adult advisory councils to ensure diverse representation in shaping brain health strategies.

Dr Francesca Farina, lead author and research assistant professor at Northwestern University in Chicago, said: "Young adulthood represents a pivotal window for intervention that could significantly reduce the risk of dementia later in life."

"To secure healthier brain outcomes, young adults must be included as key partners in research, education, and policymaking efforts."

Dr Laura Booi, senior author and senior research fellow in the Centre for Dementia Research at Leeds Beckett University, said: "There is a real appetite for young adults to learn more about their brain health. They are highly aware of cognitive and neurodiversity, with many identifying with diagnoses like ADHD or autism. This awareness drives their strong interest in understanding and improving their brain health."
