The Journal of Alzheimer’s Disease published a recent analysis of information drawn from participants in the Cardiovascular Health Study (CHS), a multisite, longitudinal study of persons age 65 and above. The 876 participants with an average age of 78 were evaluated in an attempt to correlate activity level (energy expenditure) and brain volumes. Researchers determined that there is a relationship between increasing energy output from a variety of physical activities and larger gray matter volumes. — In plain English, activities such as walking, jogging, cycling, dancing and even gardening, are correlated with brain preservation. Those people with more gray matter (correlated with physical activity) 5 years later had only one-half the risk of developing memory impairment or Alzheimer’s disease.
