An analysis of how this relates to structural abnormalities in the brain is planned. There were no significant differences between side of the carotid stenosis and whether the stenosis was symptomatic or asymptomatic.Ĭonclusion: In comparison to normative data borderline cognitive impairment is common in patients with carotid artery stenosis especially within attention/switching tasks. Performance appeared worst in TRAIL making test (Table 2). The majority of participants scored within the average or low average range (Table 1) with 24% scoring as borderline.

Results: Thirty-three participants were included: 20 males mean age 70.4 years (range 52–87). Z scores allow comparison to age matched normative data and performance was described as ranging from ‘very superior’ to ‘profound impairment’. Test Digit-symbol coding task from the WAIS (III) Centre for Epidemiologic studies-depression Scale Trails part A and B cube copy, clock drawing and orientation subsections of the MoCA).We calculated z scores for the appropriate individual assessments and an average z score for each patient as a measure of global cognitive function. A modified version of the “Hachinski 30-minute battery” was used(Hopkins verbal Learning test, Animal Naming Controlled Word Association Methods: Patients >50 years old with >50% carotid artery stenosis detected on Doppler ultrasonography but who had not had carotid endarterectomy and had no documented cognitive impairment were included. However, it may have other sequelae such as development of vascular cognitive impairment.Īims: To assess cognitive function in patients with carotid artery stenosis.
