CARDIOVASCULAR JOURNAL OF AFRICA • SAHS Biennial Congress 16-18 September 2022 59 AFRICA Submission ID: 1380 Introduction An artery is essentially made up of the intima, the media and the adventitia. The intima thickens with age and other cardiovascular risk factors due to atherosclerosis which will cause plaque or stenosis or even vessel occlusion. However, the association between carotid atherosclerosis and cognitive impairment remains uncertain. Thus, this study explored the effects of carotid artery stenosis on the cognitive function of elderly non-stroke patients of Chu-Ibn Rochd. Methods Forty patients were recruited with cognitive impairment assessed by neuropsychological tests at chu-Ibn Rochd during a 3-month period from March 2022 to June 2022. An assessment of the intima media thickness of the carotid arteries, the presence of plaques and stenoses in the carotid arteries were assessed with a B-mode ultrasound examination. Results A cross-sectional relationship between cognitive performance and carotid wall characteristics was analyzed. Intima-media thickness and carotid stenosis were found in 61% and 39% of patients respectively. Patients with carotid stenosis were associated with poor cognitive performance and those with severe stenosis >70% had a lower mini-mental state examination score than the group with mild to reduced carotid stenosis (40 to 70 %). Cognitive performance differed between patients with left and right carotid stenosis, but without any significant difference and even more so when they presented with severe right or left stenosis. Conclusion Atherosclerosis of the carotid artery is correlated with cognitive disorders in the elderly Moroccan population of Chu-ibn Rochd, even more so when the stenosis is significant.
