Imaging the centenarian brain. A computed tomographic study.
Ten healthy and mentally alert centenarians underwent cranial computed tomography (CT) using a fourth-generation CT scanner. The subjects ranged in age from 100 to 102 years, and included six women and four men. Two of them used alcohol on a daily basis and five had systolic blood pressures of at least 160 mmHg. The CT scans demonstrated considerable variation in the degree of cerebral atrophy, which had no relation to either sex, alcohol use, or hypertension. Three of the centenarians had evidence of mild periventricular white matter lucency. Although progressive cerebral atrophy is an integral aspect of the normal aging process in the very elderly, its exact relationship to cognitive function remains unclear.
