Epilepsy is one of the most common neurological diseases with a prevalence ranging from 0.5% to 2% in different sittings. The World Health Organization (WHO) estimated that nearly 80% of this burden is borne by resource-poor countries where even conventional electroencephalogram (EEG) coverage is dramatically short.

Emergent Management of Status Epilepticus.

Continuum (Minneap Minn)

June 2024

Objective: Status epilepticus is a neurologic emergency that can be life- threatening. The key to effective management is recognition and prompt initiation of treatment. Management of status epilepticus requires a patient-specific-approach framework, consisting of four axes: (1) semiology, (2) etiology, (3) EEG correlate, and (4) age.

Article Synopsis
  • NORSE is a serious condition that affects otherwise healthy individuals, leading to prolonged seizures and often poor outcomes, and may be linked to immune system dysfunction.
  • Researchers used advanced RNA sequencing to analyze brain samples from patients with NORSE and compared them to those with chronic temporal lobe epilepsy (TLE) and healthy controls, looking for connections between brain activity and immune responses.
  • Findings showed that NORSE and TLE patients had more excitatory neurons than controls, and this imbalance, along with signs of active immune responses in the brain, suggests that inflammation may play a significant role in the heightened seizure activity in NORSE.

Distinct profiles of cerebral oxygenation in focal vs. secondarily generalized EEG seizures in children undergoing cardiac surgery.

Front Neurol

Guangdong Provincial Key Laboratory of Research in Structural Birth Defect Disease, Guangzhou Women and Children's Medical Center, Guangzhou Medical University, Guangzhou, China.

Objectives: Seizures are common in children undergoing cardiopulmonary bypass (CPB). Cerebral oxygen saturation (ScO) by near-infrared spectroscopy is routinely monitored in many centers, but the relations between the levels and changes of ScO and brain injuries remain incompletely understood. We aimed to analyze the postoperative profiles of ScO and cerebral blood flow velocity in different types of EEG seizures in relation to brain injuries on MRI.

Objective: Sex determines cognitive outcome in animal models of early life seizure, where males exhibit impaired hippocampal-dependent learning and memory compared with females. The physiological underpinnings of this sex effect are unclear. Cholinergic signaling is essential for the generation of hippocampal oscillations, and supplementation of cholinergic precursors prior to status epilepticus in immature male rats prevents subsequent memory deficits.

Article Synopsis
  • - Soman causes harmful excitotoxic effects by blocking acetylcholinesterase, leading to prolonged seizures (SSE) and brain damage in models.
  • - A study tested the delayed use of the adenosine receptor agonist ENBA alongside current treatments (atropine, 2-PAM, midazolam) in rats, finding that ENBA improved seizure termination and reduced brain damage compared to midazolam alone.
  • - Despite the benefits in seizure control and neuroprotection, the combination of ENBA with midazolam resulted in lower survival rates after 14 days, suggesting that ENBA may enhance midazolam's harmful effects on neurons, requiring careful dosage adjustments.

Use of perampanel oral suspension for the treatment of refractory and super-refractory status epilepticus.

Introduction: Status epilepticus (SE) is a medical emergency associated with a significant risk of disability and death. The treatment of SE follows a step-wise approach, with limited data on ideal antiseizure medications (ASMs) for refractory and super refractory SE (RSE/SRSE). Perampanel (PER), an AMPA receptor antagonist, has shown promise in animal models but still has limited data in humans.

Background: Nodding syndrome is a poorly understood neurological disorder that predominantly occurs in Africa. We hypothesised that nodding syndrome is a neuroinflammatory disorder, induced by antibodies to Onchocerca volvulus or its Wolbachia symbiont, cross-reacting with host neuronal proteins (HNPs), and that doxycycline can be used as treatment.

Methods: In this randomised, double-blind, placebo-controlled, phase 2 trial, we recruited participants from districts affected by nodding syndrome in northern Uganda.

From the Department of Pediatrics (Muthaffar), From the Faculty of Medicine (Alyazidi), Faculty of Medicine, King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia.

Epilepsia partialis continua (EPC) is a rare type of focal motor seizure characterized by continuous, involuntary muscle contractions in a specific part of the body. These contractions usually involve rhythmic, twitching movements and can last for several hours to days. The seizures are usually limited to one part of the body and can be clonic or dystonic.

Objective: Periodic Discharges (PDs) in Status Epilepticus (SE) are historically related to negative outcome, and the Epidemiology-based Mortality Score in SE (EMSE) identifies PDs as an EEG feature associated with unfavorable prognosis. However, supportive evidence is conflicting. This study aims to evaluate the prognostic significance of interictal PDs during and following SE.

Introduction/background: Non convulsive seizures (NCS) following traumatic brain injury (TBI) may remain undiagnosed due to lack of overt clinical manifestation and can have long-term sequelae due to delay in timely treatment. Occurrence of early NCS is known to have subsequent neurologic sequelae due to excitotoxic neuronal injury.

Purpose: While spikes and sharp waves are considered as markers of epilepsy in conventional electroencephalography, ictal direct current (DC) shifts and high-frequency oscillations (HFOs) appear to be useful biomarkers for epileptogenicity. We analyzed how ictal DC shifts and HFOs were affected by focal status epilepticus and antiseizure medications (ASMs).

Methods: A 20-year-old female patient who underwent long-term intracranial electrode implantation for epilepsy surgery presented with 72 habitual seizures and a focal status epilepticus episode lasting for 4 h.

Article Synopsis
  • Some people with epilepsy can have psychosis, which means they might experience strange thoughts and feelings, and it's not always noticed.
  • A 63-year-old woman believed she was dead and didn't recognize herself, and doctors used special tests like EEG and MRI to understand her condition.
  • After giving her medication for seizures, her strange thoughts went away, showing that sometimes these thoughts can happen because of seizure activity in the brain.
