Over 70,000 people in Aotearoa New Zealand live with dementia, and this figure is set to soar to 200,000 as our population ages, placing enormous strain on the healthcare system, social services and families.
As we grapple with the rise of dementia, another urgent challenge has emerged: climate change. While the two issues may seem unrelated, the connections are becoming increasingly clear. Climate change affects our health, including the health of our brains. Environmental factors exacerbated by climate change, such as air pollution and extreme heat, have been linked to cognitive decline and increased dementia risk. The mental health impacts of climate change further compound the problem.
This convergence of challenges is the subject of research project Co-exploring Dementia Risk Reduction from a Planetary Health Perspective, funded by the Health Research Council (HRC) of New Zealand and led by Associate Professor Susanne Röhr.
The project unites science and art to highlight the shared benefits of sustainable living and dementia prevention. Previous research from around the world has provided solid evidence for the enormous opportunities for dementia risk reduction and prevention through healthy lifestyle habits and addressing social inequities at the population level.
“In addition, we need to consider environmental factors, as only a holistic approach that incorporates lifestyle, social and environmental interventions will have the maximum impact on reducing dementia risk and promoting brain health,” Dr Röhr says.
With the increasing impact of climate change, environmental risk factors cannot be overlooked, she adds.
“Adopting sustainable practices not only helps mitigate climate change but also promotes brain health. For instance, urban planning that incorporates more green spaces can enhance physical and mental wellbeing, providing protective factors against cognitive decline. Policy actions such as reducing air pollution and promoting renewable energy can have dual benefits, improving both environmental and public health outcomes.”
The project uses an innovative photovoice approach, combining photography with personal reflections to explore the links between lifestyle, environmental conditions, and brain health.
The resulting exhibition, Protecting the Planet and Our Brains: A Photographic Exploration, features the works of 14 Auckland residents aged between 40 and 65, whose images reflect their understanding of the relationship between brain health and environmental sustainability.
Dr Röhr says what was most remarkable was the recurrence of themes across the photographs and narratives created by a highly diverse, multicultural group of participants.
“This reflects some universal aspects of brain health and environmental stewardship, transcending cultural boundaries. Despite differences in backgrounds, participants shared common concerns and perspectives that speak to a collective human experience. These common themes were resilience, sustainable practices and a sense of community and belonging.”
A pop-up exhibition will be held from 20-22 September at Hayes Studio, Lake House Arts Centre at 37 Fred Thomas Drive in Takapuna, Auckland. A special celebration will be held on 21 September to mark World Alzheimer’s Day.
The full exhibition will run in the main gallery of the Lake House Arts Centre from 11-25 October, with a formal opening on 13 October where attendees can meet the artists and researchers.
