In the scenario of refractory status epilepticus, the recommended approach of intensive care treatment is limited with respect to the available pharmacodynamic variability and its impeding, severe side effects. Alternative treatment options are therefore urgently needed. In the case described, a patient with nonlesional frontal lobe epilepsy had a high-frequency series of tonic seizures, which evolved into a malignant form of status epilepticus. Co-administration of verapamil, a potent multidrug transporter inhibitor, was followed by significant reduction in seizure frequency. We discuss the putative role of verapamil and the specific risk factors for this malignant treatment course.

Background: Presenilin 2 (PSEN2) is one of three deterministic risk genes that increases the risk of early-onset Alzheimer's Disease. People with PSEN2 variants have increased risk of unprovoked seizures versus age-matched unaffected individuals yet few studies have interrogated the contributions of PSEN2 on seizure susceptibility. Critically, PSEN proteolytic capacity may be a novel regulator of hippocampal kainate-type glutamate receptors (KARs), with PSEN deletion reducing KAR availability and synaptic transmission in vitro (Barthet et al 2022).

Background: Ampicillin/sulbactam (ABPC/ SBT) is one of the most common β-lactam antibiotics for patients with status epilepticus complicated with aspiration pneumonia. It is known that β-lactam antibiotics such as penicillin aggravate epileptic seizures or status epilepticus. Here, we investigated whether ABPC/SBT aggravates seizures using electroencephalography (EEG) monitoring.

Purpose: Proton exchange rate (K) is a valuable biophysical metric. K MRI may augment conventional structural MRI by revealing brain impairments at the molecular level. This study aimed to investigate the feasibility of K MRI in evaluating brain injuries at multiple epilepsy stages.

Objective: Electroconvulsive therapy (ECT) has been occasionally applied as a treatment for super-refractory status epilepticus (SRSE). However, the effects of ECT on electrographic activity and related clinical outcomes are largely unknown. Here, we use quantitative approaches on electroencephalography (EEG) data to evaluate the neurophysiological influences of ECT and how they may relate to patient survival.

Introduction: We aim to identify risk factors that predict refractory convulsive status epilepticus (RCSE) and to develop a model for early recognition of patients at high risk for RCSE.
Methods: This study involved 200 patients diagnosed with convulsive status epilepticus (CSE), of whom 73 were RCSE and 127 were non-RCSE. Variables included demographic information, lifestyle factors, medical history, comorbidities, clinical symptoms, neuroimaging characteristics, laboratory tests, and nutritional scores.
