The size of the skull is fixed by age 7. Brain size approximates the head size until old age, when it begins to shrink. Some evidence has reported an association between small head size (and therefore less brain volume) and Alzheimer's disease. Nevertheless, other studies have found no association between a small head size and Alzheimer's disease.
