Paroxysmal pain as the only presentation of focal epilepsy.

Painful seizures can be the only feature of focal epilepsy. Its localization on a limb favors the epileptic etiology, while abdominal or cephalic paroxysmal pain is not so specific. Painful somatosensory seizures arise from operculo-insular cortex.

N170 asymmetry as an index of inferior occipital dysfunction in patients with symptomatic occipital lobe epilepsy.

Objective: Localizing epileptic foci in posterior brain epilepsy remains a difficult exercise in surgery for epilepsy evaluation. Neither clinical manifestations, neurological, EEG nor neuropsychological evaluations provide strong information about the area of onset, and fast spread of paroxysms often produces mixed features of occipital, temporal and parietal symptoms. We investigated the usefulness of the N170 event-related potential to map epileptic activity in these patients.
