Brain weights in octogenarians.
The brains of 102 octogenarians were weighed and examined at autopsy. The heaviest weighed 2075 gm, and the lightest 818 gm. They were classified by sex and by the pathologic changes. These brains were definitely lighter than the accepted normal, but somewhat heavier than a previously reported series of nonagenarian brains which showed a greater percentage of pathologic lesions.
