Donepezil Improves Gait Performance in Patients with an Acute Cerebral Infarction: A Prospective Observational Cohort Study

BACKGROUND: Hemiplegia is a common symptom after acute cerebral infarction. OBJECTIVE: This study aimed to explore the influence factors of gait performance and investigate whether donepezil could improve gait performance in patients with an acute cerebral infarction. METHODS: A total of 107 patients who experienced unilateral paresis after an acute cerebral infarction incident were enrolled in this prospectively observational study. Participants underwent a 3- month assessment. At the study's conclusion, patients were divided into 2 groups-those who received donepezil daily (observation Group) and those who did not (Control Group). RESULTS: There was a significant difference (t=3.269, P=0.001) of Wisconsin Gait Scale (WGS) score between single site infarction (27.11±6.65) and multiple sites infarction (31.54±6.42). For gender, smoking, drinking, hypertension, hyperlipidemia and diabetes, there was no difference in WGS scores between subgroups (P>0.05), respectively. The patient's admission National Institute of Health Stroke Scale(NIHSS) score had a strongly positive correlation with WGS score (r=0.850, P<0.001). Besides, age (r=0.218, P=0.024), glycosylated hemoglobin (r=0.274, P=0.004), MMSE (r=-0.261, P=0.007) and Montreal Cognitive Assessment (MoCA) (r=-0.272, P=0.005) had a weak correlation with WGS scores. Multivariate analysis showed age (95% CI: 0.042~0.188, P=0.002), admission NIHSS score (95% CI: 2.405~3.137, P<0.001) and multiple sites infarction (95% CI: 0.044~2.983, P=0.044) were independent risk factors of WGS scores. WGS scores of both observation and control groups gradually decreased after admission (P<0.001). At 3 months after admission, WGS score of the observation group was significantly lower than the control group (t=2.468, P=0.015). There were no significant differences between observation and control group at admission and 1 month after admission (P>0.05) and WGS scores of both single site and multiple sites infarction gradually decreased at one month and three months after admission (P<0.001), while there was no significant difference between two groups (P>0.05). CONCLUSION: Admission NIHSS score, age and multiple sites infarction were independent risk factors of WGS score. Donepezil could improve gait performance in patients with acute cerebral infarction.
