Parietal lobe epilepsy: the great imitator among focal epilepsies

Abstract

Scalp EEG readings of parietal lobe epilepsy patients showed a more variable scatter of interictal discharges and a lower localisation value of ictal recordings compared to temporal and frontal lobe epilepsy subjects, suggesting an increased likelihood of misidentification and mislocalisation of parietal lobe epilepsy. Combining seizure semiology with scalp interictal and ictal EEG readings facilitates a more accurate lobar classification in patients with temporal and frontal, but not parietal, lobe epilepsy.
