Researchers have found that activities like walking help prevent brain shrinkage, which may prevent dementia.

Brain size shrinks in late adulthood and can cause memory problems. Researchers wanted to see how it would affect senior’s brains. The study showed seniors who regularly walk around 10 kilometres per week showed increased grey matter volume in their brain compared to those who didn’t walk as much.

The findings were the same regardless of other risk factors such as family history. More studies need to be completed however it was suggested that walking could also help with Alzheimers.
