Weekly Walking Decreases Dementia Rates
Seniors who walk six to nine miles each week have greater volumes of gray matter in their brains and lower rates of dementia, shows a study on 299 seniors.
Subjects were asked in their 60s about how many city blocks they normally walked each week. Brain scans showed that those who walked at least 72 blocks had greater brain density. Four years later, 40 percent of subjects had either dementia or signs of cognitive impairment. However, the big walkers in the group were half as likely as those who walked the least to suffer impairments.
These findings support findings that heart health is linked to brain health. They also suggest that an exercise as simple as walking can go far to keep brains healthy.
