Continuous electroencephalogram (cEEG) recordings are being increasingly used in intensive care units (ICUs) to detect epileptic seizures and other changes. MRI scans can interrupt such recordings if the EEG electrodes need to be removed and important data can be missed. ⋯ A significant proportion of patients undergoing MRI scans with the MRI-compatible EEG electrodes had seizures that would have been missed if the MRI-incompatible EEG electrodes had been used.

Stereotactic radiofrequency amygdalohippocampectomy (AHE) has been reintroduced as an alternative treatment of mesial temporal lobe epilepsy. The aim of this study was to describe MRI changes after stereotactic AHE and to correlate the hippocampal and amygdalar volumes reduction with the clinical seizure outcome. Eighteen patients after stereotactic AHE were included. ⋯ In 3 patients, temporary meningeal syndrome developed. Results of radiofrequency AHE are promising. The volume reduction of target structures after AHE is significantly related to the clinical outcome.

De novo depression is a common psychiatric sequelae of epilepsy surgery. To date, no studies have described possible clinical correlates of de novo depression in this population. This qualitative study presents a detailed analysis of five cases of de novo depression. ⋯ All experienced post-operative marital/relationship conflict that appeared to be a catalyst for deteriorating mood. Post-operative seizures were not temporally linked to the onset of depressive symptoms. This series provides an initial account of factors associated with de novo depression following anterior temporal lobectomy and may be of use in guiding larger scale studies.

Clinical Trial
Levetiracetam in newly diagnosed late-onset post-stroke seizures: a prospective observational study.
Levetiracetam (LEV) monotherapy was investigated in 35 patients (pts) (16M/19F, 71.9+/-7.3 years of age) with late-onset post-stroke seizures (i.e. seizures occurring at least 2 weeks after an ischemic stroke) in a prospective open-label study. Overall, 27 pts (77.1%) achieved a condition of seizure freedom (defined as 1 year without seizures): 19 (54.3%) at a daily LEV dose of 1000mg, 7 (20.0%) at 1500mg, 1 (2.8%) at 2000mg. Four pts (11.4%) discontinued the drug because of intolerable side effects (drowsiness associated to gait disturbance in 1 pt, and aggressive behaviour in the remaining 3 pts); 3 pts were unresponsive at a dose of 3000mg, and 1 pt was lost at follow-up. These observations suggest that LEV exhibits safety and efficacy profiles which make it an optimal candidate as a first-choice drug against post-stroke seizures.

Comparative Study
The impact of lesions and epilepsy on personality and mood in patients with symptomatic epilepsy: a pre- to postoperative follow-up study.
To discern more static and lesion based from more dynamic epilepsy-driven features of depression and personality in focal symptomatic epilepsy, change in personality and mood was examined as a function of focus lateralization and seizure outcome after epilepsy surgery. ⋯ Apart from elevated depression and introversion scores which showed some relation to pathology, no major deviant personality features could be discerned. While seizure freedom related improvements may indicate both epilepsy and reactively driven behavioral changes, the differential recovery observed in seizure-free left versus right temporal resected patients indicate epilepsy-specific behavioral dysfunction.
