Revascularization of Asymptomatic Carotid Artery Stenosis: Cognitive Results of the CREST-2 Randomized Trials.

These robust randomized data clarify that neither stenting nor endarterectomy improves cognition beyond medical management, informing patient counseling and avoiding unnecessary procedures for cognitive indications.
