Best way to fend off dementia at any age? Break a sweat, doctors say

A study from UC San Francisco highlights that regular physical activity helps protect aging synapses, which are crucial for maintaining cognitive functions. Researchers found that physically active older adults had higher levels of proteins that support synaptic function, even in the presence of Alzheimer's-related toxins. This suggests that exercise may play a key role in preserving brain health and delaying cognitive decline, making it a valuable tool for fending off dementia.
