Regular exercise has been linked to improved brain health, reducing the risk of dementia, and a recent study published in the Journal of Alzheimer’s Disease sheds light on the underlying mechanisms. The study analyzed MRI brain scans of 10,125 individuals with an average age of 52, finding that those who engaged in moderate or vigorous exercise four days a week had larger brain volumes in key areas responsible for cognitive skills, including the hippocampus and frontal, parietal, and occipital lobes. Overall, exercisers exhibited larger volumes of gray matter (processing information) and white matter (connecting brain regions), providing valuable insights into the positive impact of physical activity on brain regions associated with memory and learning.
