Kognitivni poremećaji u bolesnika sa stenotičkim procesom karotidne arterije dominantne hemisfere mozga

Aim: Carotid artery stenosis is a progressive constriction in the process of atherosclerosis, which, as well as the attendant risks, is being considered as one of the reasons for reduction of cognitive capabilities. In this study we examined the connection between cognitive disorders and stenotic change of carotid artery supplying dominant brain hemisphere (left inner carotid artery in right handed persons and right carotid artery in left handed persons) being responsible for the primary irrigation of brain hemisphere. Methods: The study included 67 patients (36 women and 31 men), who according to their medical history did not suffer a stroke, transient ischemic attack and no carotid trombendarterectomy was performed on them, but they have an asymptomatic high level of stenosis of the dominant inner carotid artery. The control group of 30 patients consisted of patients without stenotic processes of extracranial parts of the carotid, age and sex approximately equally represented. Cognitive disorder was monitored by modified mental scale and BDI-MC test (blessed-dementia information- memory concentration test). Results: We found that there was no statistically significant difference in cognitive disorder between groups. Conclusion: Cognitive disorder is not connected to a high level of stenotic processes of the carotid arteries supplying dominant brain hemispheres.
