EEG recordings using a circumferential 10-electrode montage meet the gold standard for seizure detection

• Removing confounding factors, the overall concordance between fm-EEG and rm-EEG increased from 79.7% to 99.0%, and the sensitivity and specificity of rm-EEG compared to fm-EEG in detecting seizure cases increased to 97.5% and 100.0%, respectively.
• The concordance between fm-EEG and rm-EEG observed in Phase II… was 95%
• These findings demonstrate that differences between fm-EEG and rm-EEG can largely be explained by variability in EEG pattern classification across readers and incorporation of asymmetric clinical information into EEG interpretation rather than by true detection failure of rm-EEG as a result of electrode reduction
