Neurological manifestations of nonketotic hyperglycemia are frequently seen, with mainly symptoms of confusion or coma. While hyperglycemia-induced seizures are less common, isolated aphasic status epilepticus is very rare, difficult to diagnose, and may be unrecognized by clinicians. In this case report, a 51-year-old man who presented with confusion and incoherent speech for two weeks is discussed.

Background: Neuronal hyperexcitability has been proposed to play a key role in Alzheimer's disease (AD). Understanding the relation between this enhanced excitability and AD pathology could provide a window for therapeutic interventions. However epileptiform activity is often subclinical, hidden on scalp EEG and very challenging to assess with current diagnostic modalities.

Febrile Infection-Related Epilepsy Syndrome (FIRES) is an infrequent yet severe form of epilepsy that rapidly evolves into status epilepticus following a febrile episode. Prompt diagnosis coupled with effective treatment strategies is critical for improving patient outcomes. Herein, we describe the case of an 11-year-old male with FIRES who was successfully treated with tocilizumab, resulting in no further seizures or residual disability.

Objective: Electroencephalographic seizures (ES) are common in neonates with hypoxic-ischemic encephalopathy (HIE), but identification with continuous electroencephalographic (EEG) monitoring (CEEG) is resource-intensive. We aimed to develop an ES prediction model.

Methods: Using a prospective observational study of 260 neonates with HIE undergoing CEEG, we identified clinical and EEG risk factors for ES, evaluated model performance with area under the receiver operating characteristic curve (AUROC), and calculated test characteristics emphasizing high sensitivity.

Status epilepticus (SE) is a critical medical emergency that demands immediate and effective intervention. We report a unique case involving a 21-year-old woman with left hemimegalencephaly who was hospitalized for super-refractory status epilepticus (SRSE) that persisted for 8 weeks. Despite extensive treatment efforts including multiple anti-seizure medications, anesthetics, high-dose methylprednisolone, anakinra, magnesium infusion, and a ketogenic diet, her condition remained unchanged.

Molecules with optimized pharmacokinetic properties selectively aimed at the inhibition of STAT3 phosphorylation in brain have recently emerged as potential disease modifying therapies for epilepsy. In the current study, pharmacological inhibition of JAK1/2 with the orally available, FDA-approved drug ruxolitinib, produced nearly complete inhibition of hippocampal STAT3 phosphorylation, and reduced the expression of its downstream target Cyclin D1, when administered to rats 30 ​min and 3 ​h after onset of pilocarpine-induced status epilepticus (SE). This effect was accompanied by significantly shorter seizure duration and lower overall seizure frequency throughout the 4 weeks of EEG recording, but did not completely prevent the development of epilepsy in ruxolitinib-treated male rats.

Diagnosis and management of status epilepticus: improving the status quo.

Lancet Neurol

January 2025

Division of Epilepsy and Clinical Neurophysiology, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA.

Status epilepticus is a common neurological emergency that is characterised by prolonged or recurrent seizures without recovery between episodes and associated with substantial morbidity and mortality. Prompt recognition and targeted therapy can reduce the risk of complications and death associated with status epilepticus, thereby improving outcomes. The most recent International League Against Epilepsy definition considers two important timepoints in status epilepticus: first, when the seizure does not self-terminate; and second, when the seizure can have long-term consequences, including neuronal injury.

December 2024

The National Key Clinic Specialty, The Engineering Technology Research Center of Education Ministry of China, Guangdong Provincial Key Laboratory On Brain Function Repair and Regeneration, Department of Neurosurgery, Zhujiang Hospital, Southern Medical University, Guangzhou, 510000, China.

Background: Status epilepticus (SE) is a common severe neurological emergency. Cerebral edema caused by SE is unavoidable and may exacerbate epilepsy. Recent studies have identified cerebrospinal fluid (CSF) as a crucial fluid source of initial cerebral edema following ischemic stroke and cardiac arrest.

Article Synopsis
  • The study investigates pyroptosis, a form of programmed cell death, in the context of status epilepticus (SE), a condition marked by prolonged seizures, and how it relates to neurodegeneration.
  • Researchers induced SE in mice using pilocarpine and found increased levels of inflammatory markers and TRPM7 expression, identifying TRPM7 as a key player in neuronal damage and hyperexcitability.
  • The findings suggest that targeting TRPM7 and NLRP3 could be a potential treatment strategy for SE, as inhibiting these pathways alleviated neuronal hyperexcitability and pyroptosis.

Unexpected consequences: A case of ketamine-induced seizure in procedural sedation.

Turk J Emerg Med

October 2024

Department of Emergency Medicine, Mus State Hospital, Mus, Türkiye.

This case report describes a 32-year-old male who underwent ketamine procedural sedation and experienced a generalized tonic-clonic seizure. Despite its rapid onset and favorable tolerance profile, this case emphasizes the potential convulsive side effects of ketamine, which is commonly used for procedural sedation. While ketamine has shown promise in treating acute pain, refractory status epilepticus, and treatment-resistant depression and schizophrenia, it is associated with side effects such as hallucinations, visual disturbances, dizziness, nausea, and vomiting.

Objective: Rapid EEG devices (REDs) have demonstrated substantial benefit regarding reduced time to performance of study and diagnosis in cases where urgent EEG is needed to evaluate patients for potentially revealing nonconvulsive status epilepticus and seizures. However, urgent EEG is also important in identifying cases regarding the need for initiation of antiseizure medication as well as triaging the use of continuous EEG monitoring. Some forms of REDs have a reduced montage (RRME) with electrode derivations that are one-half of standard recordings.

Roughly 80% of the global burden of epilepsy resides in low- and middle-income countries (LMICs; WHO, 2022). Despite numerous new therapies for the treatment of epilepsy, the number of patients who remain resistant to available medications is unchanged. Additionally, no therapy has yet been clinically proven to prevent or attenuate the development of epilepsy in at-risk individuals.

Parvalbumin-positive (PV+) GABAergic interneurons in the dentate gyrus provide powerful perisomatic inhibition of dentate granule cells (DGCs) to prevent overexcitation and maintain the stability of dentate gyrus circuits. Most dentate PV+ interneurons survive status epilepticus, but surviving PV+ interneuron mediated inhibition is compromised in the dentate gyrus shortly after status epilepticus, contributing to epileptogenesis in temporal lobe epilepsy. It is uncertain whether the impaired activity of dentate PV+ interneurons recovers at later times or if it continues for months following status epilepticus.

Article Synopsis
  • - The objective of the study was to review how neonatal status epilepticus (SE) is defined and measured, focusing on literature available on seizure burden in newborns.
  • - The review analyzed 44 studies that primarily included infants with conditions like hypoxic-ischemic encephalopathy, using continuous EEG (cEEG) for SE identification, and mostly defined SE via specific seizure durations.
  • - Key findings revealed significant variability in definitions of neonatal SE, with a consistent trend showing that higher seizure burden was linked to worse outcomes in the 16 studies that explored this relationship.
