Background:
Ginkgo diterpene lactone meglumine (GDLM) could improve the functional outcome in patients with acute ischemic stroke (AIS). This study aimed to investigate the efficacy of GDLM on cognitive function in patients with AIS.
Methods:
This is a predefined exploratory analysis of the Efficacy and Safety of Ginkgo Diterpene Lactone Meglumine in Acute Ischemic Stroke trial, which was primarily designed to investigate the efficacy and safety of GDLM versus placebo on functional outcome at 100 centers in China. Cognitive function was measured using the Montreal Cognitive Assessment (MoCA) test. The primary outcomes were changes of MoCA from baseline to Day 14 and Day 90 after randomization.
Results:
A total of 3163 patients with completed data on MoCA were enrolled. There was statistically significant difference of changes in MoCA scores between the GDLM group and the placebo group from baseline to Day 14 (mean difference, 0.31; 95% confidence interval [CI], 0.08-0.53; P = 0.007) and to Day 90 after randomization (mean difference, 0.47; 95% CI, 0.22-0.72; P < 0.001). Additionally, GDLM was associated with a higher proportion of patients who reached a clinically significant level of improvement in MoCA from baseline to Day 14 (odds ratio [OR], 1.25; 95% CI, 1.08-1.44; P = 0.002) and Day 90 after randomization (OR, 1.21; 95% CI, 1.03-1.41; P = 0.02). Specially, GDLM could significantly improve the scores of visuo-spatial and executive function and language.
Conclusions:
In this predefined analysis of patients with AIS, GDLM could improve the 14-day and 90-day cognitive function compared with the placebo.
