Analysis of 1261 adult subjects, ages 25-80 yr, showed that there is a positive relationship between brain weight and body dimensions. Brain weight increases at a slower rate than body dimensions. Only a small portion of the brain varies with variation in body dimensions. Among parameters, brain weight correlates best with body surface area, followed by body height and body weight. Brain weight is related to body weight partly because it increases with increasing height. When adjusted to body dimensions, brain weight is greater for white men than for black men and for white women than for black men. The loss of brain mass proceeds at a slightly faster rate than loss of body mass.
