Anatomo-Electro-Clinical Features of Parietal Lobe Epilepsy: Insights From Scalp Video-Electroencephalography.

ABSTRACT:

Aims

To summarize the anatomo-electro-clinical characteristics of parietal lobe epilepsy (PLE) subgroups using unsupervised cluster analysis.

Methods

This retrospective cohort study included patients with drug-resistant PLE with seizure freedom after surgery and evaluated scalp video-electroencephalography (EEG) recordings from three epilepsy centers. Hierarchical cluster analysis associated interictal/ictal patterns and initial ictal semiology with anatomical subgroups.

Results

We analyzed 79 interictal EEG, 141 ictal EEG, and 141 semiological patterns in 47 patients. Cluster analysis associated interictal and ictal discharges from lateral superior parietal lobule epilepsy with centroparietal region distributions on scalp EEG, whereas discharges from other subgroups
