Post-Stroke Cognitive Impairment Incidence Meta-Analysis of 7,048 Patients

46% of first-time stroke patients develop cognitive impairment according to this meta-analysis of 11 studies. The dataset includes subgroup analyses for factors like stroke type, age, and comorbidities. Xinyu Zhang published this systematic review on figshare in April 2026.

Use Cases

• Estimate the global incidence of post-stroke cognitive impairment based on the pooled 46% rate.
• Compare risk factors like gender, stroke type, and age based on subgroup prevalence figures.
• Analyze the association between comorbidities (hypertension, diabetes) and cognitive outcomes.
• Validate or inform models for predicting cognitive decline after a first stroke.

Strengths

• Pooled results from 11 publications with a total sample population of 7,048 patients.
• Provides specific incidence rates for multiple subgroups (e.g., 54% for hemorrhagic stroke, 44% for ischemic stroke).
• Registered protocol (CRD42024611457) and uses a random-effects model for analysis.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The 30.0 KB file size suggests a very limited scope, likely containing summary statistics rather than raw patient data.
