How Exercise May Keep Alzheimer’s at Bay
Daily exercise may alter the risk of developing Alzheimer’s or change the course of the disease once it begins according to a study from The Archives of Neurology. The research looked at 201 adults between the ages of 45 and 88, differentiating between those with the APOE gene variant e4, which has been linked to Alzheimer’s, and those without the gene. Brain scans monitored levels of amyloid plaque, a sign of Alzheimer’s, as people with more plaque tend to have more memory loss. Research found that e4 positive volunteers who exercised had fewer amyloid plaques than the e4 positive volunteers who did not exercise. It is unknown whether exercise will help once plaque has already started to buildup, but the overall benefits of exercise are enough to reinforce the importance of exercise.
