Lifestyle changes can reduce dementia risk by maintaining brain plasticity — but the time to act is now

Lifestyle-related dementia risks are complex, with factors like sleep, exercise, diet and social contact interacting with things like cognitive reserve, neuroplasticity and inflammation in the body.
Exploring the interaction between the heart and the brain, known as the heart-brain axis, has shown how heart function changes due to a concussion. (Shutterstock)

Repeated concussions can alter heart activity and impact the ‘heart-brain’ axis

Concussion doesn’t just affect the brain, but the whole body. The interaction of the ‘heart-brain axis’ means that as the brain works to heal its injury, it puts extra stress on the heart.
