Recording typical events on video during simultaneous monitoring of the EEG is the landmark for differentiating epileptic seizures (ES) from psychogenic nonepileptic seizures (PNES). Nonetheless, a normal ictal EEG does not rule out ES and no single feature of an event recorded on video has proved pathognomonic of either syndrome.… Read More...
Non–rapid eye movement (NREM) sleep is known to be a brain state associated with an activation of interictal epileptic activity. The goal of this work was to quantify topographic changes occurring during NREM sleep in comparison with wakefulness.
We studied intracerebral recordings of 20 patients who underwent stereo-electroencephalography (SEEG) during presurgical evaluation for pharmacoresistant focal epilepsy.
Dysembryoplastic neuroepithelial tumors (DNETs) are World Health Organization grade 1 neoplasms, typically present as isolated cortical lesions with no associated edema. We present 3 rare cases of DNETs that were atypical in location (all were subcortical and 1 was bilateral), 2 of which displayed substantial growth over time.
Patients with temporal lobe epilepsy (TLE) show brain connectivity changes in association with cognitive impairment. Seizure frequency and lateralization are 2 important clinical factors that characterize epileptic seizures. In this study, we sought to examine an interactive effect of the 2 seizure factors on intratemporal effective connectivity based on resting-state functional magnetic resonance imaging (rsfMRI) in patients with TLE.
