The study states that, “The more energy spent, the lower the likelihood of cognitive impairment. Patients with the highest levels of energy expenditure were 90 percent less likely to become cognitively impaired than those with the lowest levels of expenditure.”
Kirk Erickson, Ph.D., an assistant professor in the department of psychology and the Center of Neural Basis of Cognition at the University of Pittsburgh, conducting studies of his own using imaging technology and found that one year of participation in modest amounts of exercise can reverse Alzheimer’s-related atrophy in parts of the brain involved in memory formation.
