This clinical article reviews the changes in the brain that occur with aging and their manifestations. Some of the lesions observed in the brains of the elderly do not necessarily manifest clinically unless a certain threshold is reached. The distinction between healthy aging and dementia is discussed. Although changes in the brain that are associated with aging cannot be prevented, the onset of the impairment of function can be delayed and neuropsychological performance can be improved by certain measures, including mental and physical exercises. Future strategies based on advances in molecular neurology are also considered.
