Risk factors for cognitive impairment in patients with first-time ischemic stroke

Objective To determine the risk factors for cognitive impairment (CI) in patients with first-time ischemic stroke. Methods The clinical data of 180 patients with ischemic stroke who were admitted to our hospital from January 2018 to December 2019 was retrospectively analyzed. Patients with MMSE score ≤24 were included into the CI group and the rest of the patients were placed into the normal group. Multivariate logistic regression was applied to describe risk factors for CI in patients with first-time ischemic stroke. Results Among the patients with first-time ischemic stroke, 96 cases (53%) developed CI, 84 cases (47%) were normal. In different subtypes of TOAST classifications, patients with large-artery atherosclerosis had the highest CI incidence (66.96%). For different infarction sites, the highest CI incidence occurred in the frontal lobe (82.35%), and the lowest was from cerebellar infarction (37.50%). The difference of CI incidences in the frontal lobe, parietal lobe, temporal lobe and occipital lobe was significant between the two groups (P 6.53 mg/L, Hcy >13.84 μmol/L, NIHSS score >4.37, VD Conclusion The study showed a high CI incidence in patients with preexisting ischemic stroke. Age ≥60 years old, history of diabetes mellitus, CRP >6.53 mg/L, Hcy >13.84 μmol/L, NIHSS score >4.37 score, VD
