Abstract
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.
