Abstract:
Objective Carotid artery stenosis is closely related not only with the cognitive function impairment, but also can cause patients to physical fatigue and a series of consequences.The aim of this study was to investigate the correlation between carotid artery stenting for carotid artery stenosis in patients with cognitive function improvement effect and fatigue and cognitive function in this paper. Methods One hundred cases of clinical data of patients with carotid artery stenosis of carotid artery stentingwere analyze pro-spectively.The cognitive scales of mini mental state examination (mini mental scale state examination, MMSE), Montreal cognitive as-sessment(Montreal cognitive, assessment, MoCA), activities of daily living scale (activities of dailyliving, ADL), fast vocabulary test ( verbal fluency) , Webster's count test, digit span test( working memory) , Digit Symbol Substitution Test ( speed) and the the fatigue scales of fatigue assessment scale-14 ( Fatigue Scale-14, FS-14) , fatigue severity scale ( FatigueSeverity Scale, FSS-9) were observed before and 3, 6 months after surgery.The correlation between fatigue and cognitive impairment was also analyzed Results Operation was successful in all patients, and no serious complications occurred after surgery.Patients'clinical symptoms were significantly im-proved compared with those on admission.MMSE, MoCA, ADL, verbal fluency test, Wechsler arithmetic, digit span and digit symbol substitution test results showed that, the scores were significantly improved compared with those on admission( P<0.05) , and with the time prolonging, cognitive function improved more obviously( P<0.001) .Compared with before operation,FS-14 score [ ( 7.11±1.37) vs (4.38±0.97)] and FSS-9 scores were significantly decreased6 months after operation, [(52.45±6.77) vs (43.29±7.21)](P<0.05). The correlation coefficient of FS-14 and MMSE, FFS 9 and MMSE were -0.357, -0.311 6 months after surgery, and the correlation coefficientof FSS-14 and MoCA, FSS-9 and MoCA were -0.547,-0.351, which showed a significant negative correlation (P<0.05). Conclusion Carotid artery stenting therapy can improve cognitive function and fatigue in patients with carotid artery stenosis, and the effect was more significant with the time prolonging, and there was a certain correlation between fatigue and cognitive impairment.
