Research from UT Southwestern found that people who had accumulation of amyloid beta in the brain – a hallmark of Alzheimer’s disease – experienced slower degeneration in a region of the brain crucial for memory if they exercised regularly for one year.

Although exercise did not prevent the eventual spread of toxic amyloid plaques blamed for killing neurons in the brains of dementia patients, the findings suggest an intriguing possibility that aerobic workouts can at least slow down the effects of the disease if intervention occurs in the early stages.
