A decades-long study involving older Australians has demonstrated that targeted cognitive training can significantly reduce the risk of cognitive decline, including Alzheimer’s disease and other forms of dementia. The research, published in January 2025, found that participants engaged in personalized coaching programs focusing on physical activity, brain training, nutrition, or managing depression and anxiety experienced measurable cognitive benefits.
The trial involved individuals without a dementia diagnosis but carrying at least two major risk factors for the condition. Half of the participants received the active intervention, with coaching modules tailored to their specific risk profiles. Researchers at the University of New South Wales (UNSW) reported a boost in cognitive function among those who participated.
While the study did not guarantee prevention of dementia, it highlighted the potential of lifestyle interventions to bolster brain health. Separate research, detailed in a 20-year trial, indicated that specific types of brain-training exercises – those emphasizing speed of processing – were linked to a lower risk of developing dementia. This suggests that not all cognitive exercises are equally effective.
Dementia Training Australia (DTA) offers online courses designed for first responders and volunteers, aiming to improve understanding of dementia symptoms and its impact on brain function and behavior. These courses provide accessible education for those supporting individuals living with dementia or experiencing memory problems. The DTA as well offers a four-hour introductory course with a certificate of completion.
Experts emphasize the brain’s capacity to adapt and change throughout life, even in later years. Mental exercise, including activities like reading, puzzles, painting, playing musical instruments, and learning new languages, can help build new brain cells and strengthen connections between them, creating a “cognitive reserve” that may help the brain cope with damage. Dementia Australia provides resources and guides on maintaining brain health, including a BrainTrack app for monitoring cognitive function and sharing data with healthcare professionals.
The National Dementia Helpline, available 24/7, offers expert information, advice, and support to those affected by dementia. The helpline can be reached at 1800 100 500.
