Table 1. Patients with MAP+ findings in whom the MAP+ regions were only partially resected or had not been included in the resection (P1-P10).Included in the table are patient demographics, pre and post-operative seizure types, frequency and time of seizure recurrence, type of invasive evaluation, surgical data and results of postoperative scalp EEG recordings. Note that P4P5 had two surgeries (1st) and (2nd) and became seizure following their second surgery.For this Table and Table 2, patients whose type of seizures changed are marked with * in the “post-op seizure frequency” column. Abbreviations for Tables 1-4:SDG=subdural grid. DE=depth electrode. SEEG=stereotactic EEG. M=male. F=female. L=left. R=right. ED=epilepsy duration.BAT = Bilateral Asymmetric Tonic seizure; GTC= Generalized Tonic clonic seizure. d=day. wk=week. mo=month. HS=hippocampal sclerosis. FCD=focal cortical dysplasia.↑=increase. ↔=no change. ↓=decrease.
