Abstract

Common effects of aging on the brain include reduced brain volume and weight caused by neuronal atrophy and reduced synaptic density and increase in cerebrospinal fluid volume. The thalamus and hypothalamus are particularly vulnerable to effects of aging. Neuron number is relatively preserved in healthy aging. Patterns of atrophy and neuropathological changes differentiate normal from various types of pathologic aging. The anterior hippocampus shows marked atrophy in patients with Alzheimer’s disease compared with healthy aging.
