This study aimed to determine the relationship of GG with cognitive function after ischemic stroke or transient ischemic attack (TIA).Methods: Patients included were enrolled from a subgroup of China National Stroke Registry-III (CNSR-III). Cognitive function was assessed by the Beijing edition of the Montreal cognitive assessment (MoCA) scale. Post-stroke cognitive impairment (PSCI) was diagnosed as a MoCA score≤ 22. Post-stroke cognitive decline (PSCD) was defined as a decrease of > 2 points on the MoCA score between the 3-month and 1-year assessments. GG was calculated using admission blood glucose minus hemoglobin A1c-derived average blood glucose. Multivariable logistic regression analysis was used to evaluate the correlation between GG and cognitive function.Results: We enrolled 767 patients with a median age of 60 years old, including 247 (32.2%) patients with PSCI in 3 months, 228 (29.73%) with PSCI in 1 year, and 166 (21.64%) patients with PSCD. The highest GG levels were related to PSCI in 3 months after adjusted for multiple potential confounders (adjusted odd ratio (OR): 2.021, 95% CI: 1.055– 3.869, P=0.0338), but not in patients with PSCI in 1 year or PSCD. No significant interactions for the impact on PSCI were observed in subgroups (P interaction > 0.05 for all).Conclusion: Our findings show that GG is associated with acute post-stroke cognitive impairment, but not with the long-term cognitive impairment or cognitive decline.Keywords: cognitive function, glycemic gap, stroke, transient ischemic attack |
