Less Walk, Brain can shrink

Goo health - Walking distance of six miles or 9.66 kilometers in a week could be a solution to prevent brain shrinkage and against dementia. It delivered a number of U.S. researchers on Wednesday (14/10/2010).
A study conducted on 300 people in Pittsburgh, USA, who noted how far they walk each week's show, those who walked at least six miles or 9.66 kilometers are less prone to age-related brain shrinkage than those who walked less than that.

"Depreciation is the size of the brain in late adulthood can lead to problems in memory. Our results should encourage drafted a good physical exercise for the elderly as a promising approach to preventing dementia and Alzheimer's disease," said Kirk Erickson of the University of Pittsburgh, The U.S., whose research appears in the journal Neurology.

Alzheimer's disease, the most common form of dementia, slowly kill brain cells. Activities such as walking has been shown to increase brain volume.

Erickson and his colleagues conducted a study to see whether the person has to walk a lot better bargaining value to combat the disease.

They conducted a study on 299 dementia-free volunteers on a regular basis and record how far they walk in a week.

Nine years later, researchers took brain images of each volunteer to measure their brain volume.

After four years, they re-do the testing to see if there are volunteers who experience cognitive impairment or dementia.

They found that people who walk approximately six to nine miles or 9.6 km-14, 49 miles in a week have a risk of memory impairment 50 percent less than those who walk less than that in a week.

"Our results in line with the data indicates that aerobic activity induces a number of kaskada cells that can increase the volume of gray matter," said the research team was.

They say, further research needs to be done on the effects of exercise in people with dementia. However, in the absence of effective treatment for Alzheimer's, a walk is probably the one thing you can do to help.

"If regular exercise for middle-aged people can improve the health of the brain and improve memory and thinking in the future, then it just became one of the reasons for doing regular exercise at every age group, an effort to improve public health," said Erickson.

Currently there are no drugs that can stop the progression of Alzheimer's disease, which affects more than 26 million people in the world.
