Recent research on cytokines associated with anti-N-methyl-D-aspartate receptor encephalitis by Ya-Xin Zheng

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune inflammatory disease of the central nervous system, and little is known about its immune mechanism at present. There is a lack of disease-related biomarkers in cerebrospinal fluid except anti-NMDAR antibody, which leads to delayed diagnosis and treatment in some patients. Therefore, there has been an increasing number of…

Current and Emerging Pharmacotherapy for Menstrual Migraine: A Narrative Review by Claire E J Ceriani

INTRODUCTION: In this article, we discuss menstrual migraine (MM), which can be categorized as menstrually related migraine (MRM) or pure menstrual migraine (PMM). MM attacks are often longer, more severe, and harder to treat than other migraine attacks. Appropriate treatment strategies include acute treatment, short term preventive treatment, and daily preventive treatment, depending on the…

Inhibiting PAC1 receptor internalization and endosomal ERK pathway activation may ameliorate hyperalgesia in a chronic migraine rat model by Lily Zhang

CONCLUSIONS: Our results demonstrate that inhibition of PAC1 receptor internalization could effectively improve allodynia in CM rats by restraining ERK signaling pathway activation in a chronic migraine rat model. Modulation of receptor internalization may be a novel perspective to explore specific mechanisms of PACAP signaling activation in the trigeminal vascular system.

KCNH2 variants in a family with epilepsy and Long QT syndrome: a case report and literature review by Yu Zhou

CONCLUSION: We report a KCNH2 Arg 744* pathogenic variant in a family with both epilepsy and LQTS. This study expands the clinical phenotype of the Arg 744* KCNH2 pathogenic variant. In the context of channelopathies, because of the genetic susceptibility of the brain and the heart, the risk of comorbidity should be considered. This also…

Focal tonic seizures with asymmetrical posturing could allow voluntary movements: a lesson to not be misled for a non-epileptic event by Mitsumasa Fukuda

This report documents the clinical features of supplementary motor area seizures with voluntary movements in two patients. The first case describes a 13-year-old boy with a 2-year history of nocturnal seizures, characterized by an asymmetrical brief tonic posture followed by bilateral rapid hand shaking, but without impaired awareness. Magnetic resonance imaging revealed no abnormalities. Video…

Lack of structural brain alterations associated with insomnia: findings from the ENIGMA-Sleep Working Group by Antoine Weihs

Existing neuroimaging studies have reported divergent structural alterations in insomnia disorder (ID). In the present study, we performed a large-scale coordinated meta-analysis by pooling structural brain measures from 1085 subjects (mean [SD] age 50.5 [13.9] years, 50.2% female, 17.4% with insomnia) across three international Enhancing NeuroImaging Genetics through Meta-Analysis (ENIGMA)-Sleep cohorts. Two sites recruited patients…

Pre-stimulus gamma power in human posteromedial cortex shows supra-modal mechanisms in predicting the amplitude and latency of task-induced suppression by Jie Ma

Upon repetitively performing the same well-practiced task on identical bottom-up stimuli, our performance still varies. Although it has been well documented that elevated pre-stimulus baseline activity in the human default-mode network impairs the subsequent task performance, it remains unknown (i) the fine-grained temporal dynamics and (ii) whether the underlying neural dynamics are supra-modal or modality-specific.…

Neural oscillations after acute large artery atherosclerotic cerebral infarction during resting state and sleep spindles by Guoli Zeng

Electroencephalogram-microstate analysis was conducted using low-resolution electromagnetic tomography (LORETA)-KEY to evaluate dynamic brain network changes in patients with acute large artery atherosclerotic cerebral infarction (LAACI) during the rest and sleep stages. This study included 35 age- and sex-matched healthy controls and 34 patients with acute LAACI. Each participant performed a 3-h, 19-channel video electroencephalogram test.…

Remote effects of temporal lobe epilepsy surgery: long-term morphological changes after surgical resection by T Campbell Arnold

OBJECTIVE: Epilepsy surgery is an effective treatment for drug-resistant patients. However, how different surgical approaches affect long-term brain structure remains poorly characterized. Here we present a semi-automated method for quantifying structural changes after epilepsy surgery and compare the remote structural effects of two approaches, anterior temporal lobectomy (ATL) and selective amygdalohippocampectomy (SAH).

Antiepileptogenesis after Stroke – Trials and Tribulations: Methodological Challenges and Recruitment Results of a Phase II Study with Eslicarbazepine Acetate by Matthias J Koepp

There is currently no evidence to support the use of antiseizure medications to prevent unprovoked seizures following stroke. Experimental animal models suggested a potential antiepileptogenic effect for eslicarbazepine acetate (ESL), and a Phase II, multicentre, randomised, double-blind, placebo-controlled study was designed to test this hypothesis and assess whether ESL treatment for 1 month can prevent…

Combined Therapeutics: Future Opportunities for Co-therapy with Thrombectomy by Phavalan Rajendram

Stroke is an urgent public health issue with millions of patients worldwide living with its devastating effects. The advent of thrombolysis and endovascular thrombectomy has transformed the hyperacute care of these patients. However, a significant proportion of patients receiving these therapies still goes on to have unfavorable outcomes and many more remain ineligible for these…
