Landmark Trial Finds Restoring Blood Flow Does Not Improve Cognition in Asymptomatic Carotid Artery Disease Patients

A major clinical trial led by the University of Alabama at Birmingham has revealed that while patients with severe carotid artery narrowing often experience subtle cognitive deficits, surgical or minimally invasive procedures to restore blood flow do not improve cognitive performance. The findings suggest a more complex relationship between carotid artery disease and cognition, potentially involving broader vascular changes in the brain.
