Posterior cortical atrophy: Reorganization of the dorsal attention network and its implications on volume loss and clinical performance

These findings suggest that within- and between-network connectivity of the dorsal attention network, both within key regions and the entire network, was disrupted in PCA patients. However, this network did not show disrupted connectivity with the core PCA networks. Within-network connectivity disruptions in the dorsal attention network are associated with aspects of memory function, and to some extent, with volume loss.
