Alzheimer's vs. Aging (IMAGE) University of Texas at Dallas Caption Alzheimer’s disease and aging are associated with distinct patterns of brain network disruption. Alzheimer's (left) exerts widespread impacts on brain connectivity, disrupting both higher order cognitive networks and sensory and motor networks. In contrast, healthy aging (right) is limited to disruption of cognitive networks and spares sensory and motor networks.
