A groundbreaking online program has proven successful in boosting cognition among older adults, offering new hope in the fight against cognitive decline and dementia. The trial, led by Professor Henry Brodaty AO of UNSW’s Centre for Healthy Brain Ageing (CHeBA), involved over 6,000 participants aged 55-77 and is the largest internet-based study of its kind.
The program, called Maintain Your Brain, targeted key lifestyle factors linked to dementia risk, including physical activity, nutrition, brain training, and mental health. Participants received personalised coaching in two to four modules based on their risk factors. Recommendations included following a Mediterranean diet, engaging in regular moderate-to-vigorous exercise, and completing computerised brain-training exercises. A control group received general health information.
After three years, participants who followed the program showed significantly better cognition compared to the control group. Both groups improved, but the intervention group demonstrated the greatest benefit ever recorded in a randomised trial for preventing cognitive decline. Notably, those aged 55-65 benefited more than older participants, suggesting earlier interventions may yield even greater results.
Paddy Goldsmith, an 82-year-old participant from Bowral, shared how the program transformed her life. She continues to practice strength training, balance exercises, and brain training—habits she adopted during the trial.
Researchers emphasise that personalisation is key. Unlike previous trials focusing on single risk factors, this program addressed multiple areas, making it more effective. It also highlights the potential for scalability, with hopes of rolling it out nationwide to reduce dementia prevalence.
While limitations exist—such as a lack of diversity among participants—the findings underscore the importance of early, tailored prevention strategies. With further investment, this program could pave the way for broader access, helping Australians maintain brain health as they age.
