Exercise and Brain Health

Exercise, even at moderate levels, is linked with maintaining brain health and size and reducing dementia risks as people age. Researchers from multiple institutions reviewed brain scans from 10,125 healthy middle-aged men and women, and analyzed the connection between activities like walking, running or sports participation, with the volume of grey and white matter in the brain. Findings showed that even ‘lower’ physical activity levels—fewer than 4,000 daily steps—are related to maintenance of brain tissue.
“Our research links regular physical activity to larger brain volumes, suggesting neuroprotective benefits. This large sample study furthers our understanding of lifestyle factors in brain health and dementia prevention,” says study co-author, Somayeh Meysami, MD, assistant professor of neurosciences at Saint John’s Cancer Institute and the Pacific Brain Health Center in Santa Monica, California.

The study on exercise and brain health is published in the Journal of Alzheimer’s Disease (2023; doi: 10.3233/JAD-230740).
