Your brain’s best defence against ageing isn’t in a bottle
Forget the brain-training apps, miracle pills and superfoods. The secret to keeping your mind sharp for life is far simpler – and it comes down to everyday choices, according to CQUniversity’s Professor Ken Purnell.
As Head of Educational Neuroscience, Professor Purnell says the science is clear: genetics play a role, but lifestyle has the biggest impact on how well our brains age.
“While we can’t change our genes, we can shape how our brains age,” he said.
“It’s not about one magic fix though – it’s about moving more, eating smart, sleeping well, staying curious and staying connected.”
He also suggested controlling blood pressure, sugar intake and stress can keep the brain sharper for longer.
“There’s also evidence that suggests daily abdominal breathing can help to combat stress and in turn keep brains sharper for longer.”
Neuroscience research shows the brain remains adaptable well into later life, capable of rewiring and strengthening through learning, activity and social interaction.
“Neuroplasticity means the brain can adapt at any age,” Professor Purnell explained.
“Simple things like taking the stairs, walking the dog, or trying a new hobby build a buffer that protects against decline.”
And while ageing is inevitable, decline doesn’t have to be.
“It’s never too late. Small, daily choices really do add up to lasting brain health,” Professor Purnell said.
CQUniversity’s pioneering discipline of Educational Neuroscience continues to explore how brain science can support learning and health and wellbeing across all stages of life.
