Key result
Patients with asymptomatic carotid artery stenosis exhibited substantial deficits in mental speed, learning, visuospatial abilities, verbal processing, and deductive reasoning versus healthy controls.
Why the study?
Does asymptomatic carotid artery stenosis associate with cognitive performance deficits compared to healthy controls?
Case-Control
Does asymptomatic carotid artery stenosis associate with cognitive performance deficits compared to healthy controls?
Asymptomatic carotid artery stenosis is associated with non-specific cognitive impairments, suggesting it may be an indicator of widespread cerebral vascular disease.
May support cognitive screening in asymptomatic carotid stenosis; leaves open causality and revascularization effects.
A total of 20 subjects with asymptomatic carotid artery stenosis (ACAS) and a group of healthy controls were compared as to their cognitive performance. Subjects with ACAS showed substantial deficits on tasks of mental speed, learning, visuospatial abilities, verbal processing and deductive reasoning. The cognitive profile of ACAS--subjects indicated non-specific impairment, possibly related to widespread cerebral vascular disease, of which the presence of ACAS may be one indicator.

Benke et al. (1991) conducted a case-control in Asymptomatic carotid artery stenosis. Asymptomatic carotid artery stenosis vs. Healthy controls was evaluated on Cognitive performance. Patients with asymptomatic carotid artery stenosis exhibited substantial deficits in mental speed, learning, visuospatial abilities, verbal processing, and deductive reasoning versus healthy controls.
