Exercise helps keep your brain in shape (click for more):
"A fast spin on the dance floor or taking daily walks might help keep the brain in top shape as people age -- and might reduce the risk of developing age-related diseases such as Alzheimer's or Parkinson's, experts now say. Both Alzheimer's and Parkinson's are degenerative, incurable diseases of the brain. Both are more common in older people; together they afflict more than 5 million people in the United States. Alzheimer's causes memory problems, and Parkinson's leads to tremors and shakiness, but the diseases often overlap: Some people with Parkinson's also have memory loss. Growing evidence now suggests that lifestyle factors such as diet, exercise and challenging activities, might help ward off or delay the onset of neurodegenerative diseases, possibly by building connections between brain cells or even spurring the production of new brain cells. People who power up the brain in this way may have a better shot at reaching old age with a brain that still performs at top speed, says Elizabeth Edgerly, a brain expert at the Alzheimer's Association. To keep the brain healthy: • Stay fit. Physical activity boosts the blood supply to the brain, and that keeps brain cells well nourished. Edgerly recommends taking a walk, swimming, yoga or anything that's physically active three to five days a week. Spend about 30 minutes a day on such activities if you can, but a study suggested that even a 15-minute daily walk could reduce the risk of Alzheimer's... |
