Greater caloric expenditure is associated with more brain matter.
Good news (again) for those who exercise! Individuals with or without Alzheimer's disease who are physically active tend to have 5% greater brain gray matter volume than those who are less physically active. A recent study of 876 individuals who were approximately 78 years old compared those who expended 3434 calories per week with those who expended 348. The results were reported in an abstract at the RSNA meetings last week.
