Correlation Between Liver Function and Risk of Post-Stroke Epilepsy.

Area of Science:

• Neurology
• Hepatology
• Clinical Research

Background:

• Abnormal liver function is often linked to epilepsy.
• Limited large-scale clinical evidence exists for liver function's correlation with post-stroke epilepsy.
• This study addresses the need for robust data on this association.

Purpose of the Study:

• To investigate the correlation between liver function and secondary epilepsy following acute ischemic stroke.
• To identify specific liver function parameters associated with epilepsy risk post-stroke.

Main Methods:

• Retrospective analysis of 21,459 patients with acute ischemic stroke from the Dryad database.
• Multivariate regression and cross-sectional analysis to assess the correlation.
• Saturation effect analysis and ROC curve analysis to determine thresholds and predictive value.

Main Results:

• Significant correlation found between liver function (AST and ALT) and secondary epilepsy risk post-stroke.
• Identified fold points for AST (39.3 U/L) and ALT (23.3 U/L) associated with epilepsy risk.
• Elevated AST and ALT levels below these thresholds correlated with increased epilepsy risk; AST showed high predictive value (AUC 0.8101).

Conclusions:

• Provides evidence for a link between liver function and post-stroke epilepsy.
• Suggests that managing liver dysfunction in stroke patients may reduce seizure incidence.
• Calls for further high-level evidence studies to confirm these findings.
