The reasons for failure of surgical treatment for mesial temporal lobe epilepsy (MTLE) associated with hippocampal sclerosis (HS) remain unclear. This retrospective study analyzed seizure, cognitive, and psychiatric outcomes, searching for factors associated with seizure relapse or cognitive and psychiatric deterioration after MTLE-HS surgery.

Seizure, cognitive, and psychiatric outcomes were reviewed after 389 surgeries performed between 1990 and 2015 on patients aged 15–67 years at a tertiary center. Three surgical approaches were used: anterior temporal lobectomy (ATL; ...

Inhibition of the mammalian target of rapamycin (mTOR) pathway reduces epileptogenesis in various epilepsy models, possibly by inhibition of inflammatory processes, which may include the proteasome system. To study the role of mTOR inhibition in the regulation of the proteasome system, we investigated (immuno)proteasome expression during epileptogenesis, as well as the effects of the mTOR inhibitor rapamycin.

The expression of constitutive (β1, β5) and immunoproteasome (β1i, β5i) subunits was investigated during epileptogenesis using immunohistochemistry in the electrical ...

To report the presurgical workup, surgical procedures, and outcomes in a series of pediatric patients with drug-resistant epilepsy involving the perisylvian/insular regions.

We retrospectively assessed 16 pediatric patients affected by drug-resistant focal epilepsy involving perisylvian/insular regions, who consecutively underwent tailored resective surgery. All patients underwent a detailed presurgical workup, which included the analysis of the anatomoelectroclinical correlations with scalp electroencephalography (EEG) and/or with stereo-electroencephalography (SEEG), brain magnetic resonance imaging (MRI), and comprehensive cognitive and neuropsychological evaluations. After ...

To determine changes in glucose metabolism and the enzymes involved in the hippocampus ictally and postictally in the acute mouse flurothyl seizure model.

[U-¹³C]-Glucose was injected (i.p.) prior to, or following a 5 min flurothyl-induced seizure. Fifteen minutes later, mice were killed and the total metabolite levels and % ¹³C enrichment were analyzed in the hippocampal formation using gas chromatography–mass spectrometry. Activities of key metabolic and antioxidant enzymes and the phosphorylation status of pyruvate dehydrogenase were measured, ...

This study aimed to identify early clinical, magnetic resonance imaging (MRI), and electroencephalographic (EEG) characteristics of neuronal ceroid lipofuscinosis type 2 (CLN2) disease to enable early diagnosis, thus providing the key to early treatment, and optimized care and outcomes.

Retrospective clinical chart review of a series of patients diagnosed with CLN2 disease from 2005 to 2015 at a single center in Italy. Clinical, MRI, and EEG findings were reviewed.

A total of 14 patients were included. For ...

Technology for localizing epileptogenic brain regions plays a central role in surgical planning. Recent improvements in acquisition and electrode technology have revealed that high-frequency oscillations (HFOs) within the 80–500 Hz frequency range provide the neurophysiologist with new information about the extent of the epileptogenic tissue in addition to ictal and interictal lower frequency events. Nevertheless, two decades after their discovery there remain questions about HFOs as biomarkers of epileptogenic brain and there use in clinical practice.
