Implication

Randomized trial explores language lateralization in epilepsy, highlighting implications for surgical outcomes.

Key Points

This study aims to investigate language lateralization differences in patients with left-sided epilepsy compared to healthy individuals, focusing on Broca’s and Wernicke’s areas.
Retrospective analysis of 36 epilepsy patients with left-sided foci and 45 healthy controls (2018–2023).
Computed functional connectivity using 12 language-related seed points in resting-state fMRI data to generate activation maps and laterality indexes.
Utilized SEEG cortical stimulation and postoperative follow-up to verify clinical reliability.
Non-classical language dominance was observed in 69.4% of epilepsy patients versus 45.5% in controls (p = 0.024).
Wernicke’s area showed higher non-classical dominance (81.8%) than Broca’s area (50.0%).
Laterality index consistency was 83.3% (Kappa = 0.586) for the activation map, with a reliability of 75.0% (Kappa = 0.40) for regional mapping.
