Long‐lasting remodeling of astrocytes in an Scna1+/− mouse model of Dravet syndrome

Epilepsia, EarlyView.
Abstract Objective Dravet syndrome (DS) is a prototypical developmental and epileptic encephalopathy caused by mutations in the SCN1A gene, leading to loss of function of the voltage‐gated sodium channel Naᵥ1.1. The latter causes early onset drug‐resistant seizures and enduring cognitive and behavioral deficits.

Tissue oxygenation dynamics during transition from seizure to spreading depolarization in rat brain

Epilepsia, EarlyView.
Abstract Objective Spreading depolarization (SD) is a phenomenon underlying various neurological conditions, including epilepsy. Researchers have suspected that local tissue oxygenation breakdown induces spontaneous SD. In this study, we investigated the relationship between spontaneous epileptic seizures and SD, with a focus on the role of local ...

Elevation in body temperature may increase susceptibility to cortical spreading depression in a rat model

Neuroscience Research
One characteristic of migraine is recurrent headache attacks, which are known to be induced by changes in climatic variables such as atmospheric pressure, humidity, and outside temperature.

The CGRP receptor antagonist BIBN4096 inhibits prolonged meningeal afferent activation evoked by brief local K+ stimulation but not cortical spreading depression-induced afferent sensitization

PAIN Reports, 2018
. Introduction:. Cortical spreading depression (CSD) is believed to promote migraine headache by enhancing the activity and mechanosensitivity of trigeminal intracranial meningeal afferents.

A consensus roadmap for post‐traumatic epilepsy: Clinical biomarkers, research priorities, policy barriers, and pathways to interventional trials

Epilepsia, EarlyView.
Abstract Understanding the mechanisms underlying post‐traumatic epilepsy (PTE) following traumatic brain injury (TBI), and developing strategies to prevent or modify its progression, has been the focus of large collaborative efforts within the epilepsy and TBI research communities for over a decade.

Familial Hemiplegic Migraine with Prolonged Coma and Hyperthermia: ATP1A2 Gene Mutation Case Report in a Single Saudi Family.

Journal of Biochemical and Clinical Genetics, 2019
Background: Familial hemiplegic migraine (FHM) is a rare disorder presented commonly with coma, hyperthermia, and headache. FHM is usually associated with fully reversible motor weakness as a specific symptom of aura.

Dual role of spreading depolarization in an epileptic focus

Epilepsia, EarlyView.
Abstract Objective Spreading depolarizations (SDs) are often associated with epileptic discharges. Although SDs are traditionally thought to contribute to postictal depression and termination of epileptic discharges, seizures may also occur during SDs or may even follow SDs, suggesting that interactions between SD and seizures are more complex.

Effect of epileptogenesis on hypercapnic cardioventilatory response in kainic acid rats

Epilepsia, EarlyView.
Abstract Objective Cardioventilatory failure is the leading mechanism proposed to underlie sudden unexpected death in epilepsy (SUDEP), which occurs predominantly at night in patients with generalized tonic–clonic seizures. Interictal hypercapnic cardioventilatory responses are suggested to be involved, as they are ablated in chronically epileptic ...

Aura and osmophobia are associated with the IL1A -889C > T (rs1800587) variant in migraine

Arquivos de Neuro-Psiquiatria
Background Migraine belongs to the group of primary headaches, affecting 14.4% of the global population. The pathophysiological mechanisms of migraine involve the interplay between hypothalamic activation, cortical spreading depression ...

Corticocortical evoked potential amplitude is altered by cortical stimulation in epilepsy

Epilepsia, EarlyView.
Abstract Objective Neurostimulation is an established therapy for drug‐resistant epilepsy, but optimizing stimulation parameters remains a major challenge. Corticocortical evoked potential (CCEP) amplitude may serve as an immediate biomarker of neurostimulation effects, enabling rapid parameter optimization.
