Risk factors for post-stroke fatigue: a Meta-analysis

Abstract

Objective To explore effect of internal carotid artery (ICA) stenting on mild cognitive impairment (MCI) of patients with asymptomatic ICA stenosis. Methods Fifty-four patients with severe ICA stenosis (stenosis rate ≥ 70%) from October 2016 to September 2018 were studied. Cognitive function was examined in 54 patients with asymptomatic ICA stenosis 24 h before operation and 1 month, 3 months, 6 months after operation. Cognitive function was assessed with the Mini-Mental State Examination (MMSE), Trail Making Test (TMT) and Stroop Color-Word Test (SCWT). Results There were statistical differences in MMSE (P = 0.000), time of TMT-A and TMT-B (P = 0.000, 0.000), time of SCWT-A, SCWT-B and SCWT-C (P = 0.000, 0.036, 0.000), and correct number of SCWT-A (P = 0.005) before and after ICA stenting. MMSE, time of TMT-A, TMT-B and SCWT-A at 3 and 6 months after stenting were shorter than before and one month after stenting (P < 0.05, for all), while time of SCWT-C was shorter than before stenting (P < 0.05, for all). Time of SCWT-B at 6 months after stenting was shorter than before stenting (P < 0.05, for all). Correct number of SCWT-A at 6 months after stenting was higher than before and 3 months after stenting (P < 0.05, for all), which at 3 monthes after stenting was lower than one month after stenting (P < 0.05, for all). Conclusions ICA stenting can help to improve the MCI patients with asymptomatic ICA stenosis.
