The impact of early life experiences on inhibitory control and working memory.

Introduction: Adverse childhood experiences (ACEs) are a general term for a large group of nonequivalent situations that have the potential to traumatise a child. This risk factor is caused by a sensitive period of brain development, which is based on myelination, creation of synaptic connections and pruning. Dramatic environmental events during this period, such as history of institutionalisation, can disrupt optimal developmental pathways, leaving biological scars for life.

From evidence to care delivery: Opportunities and risks in health and science policy. A position paper of the Association of the Scientific Medical Societies in Germany (AWMF).

Objective: After over 25 years of developing clinical practice guidelines, the Association of the Scientific Medical Societies in Germany (AWMF) held a symposium to discuss the following topics in order to improve the way evidence is implemented in the delivery of care: expansion of the data pool for guideline development, the regulatory policy framework for this expansion, the transfer of clinical practice guideline statements to medical practice, the associated opportunities and risks resulting from the European legislation.

Methods: The AWMF held its Berlin Forum on 27 April 2022 where experts from scientific medical societies and national institutions in the healthcare sector reported their experiences and perceptions on the topics mentioned. Three writing groups compiled the key statements from these contributions to and discussions made at the Berlin Forum into a position paper.

Membrane potential states gate synaptic consolidation in human neocortical tissue.

Synaptic mechanisms that contribute to human memory consolidation remain largely unexplored. Consolidation critically relies on sleep. During slow wave sleep, neurons exhibit characteristic membrane potential oscillations known as UP and DOWN states.

Working memory deficit in patients with focal epilepsy is associated with higher interictal theta connectivity.

Objective: Interictal cognitive disturbances are frequent in patients with focal epilepsies and the links with alteration of resting state brain oscillations are not well known. Changes in theta oscillations, may contribute to cognitive impairment. This study aimed to investigate whether changes in theta activity are related to cognitive disturbances.

Behind the scenes: exploring neurological journal editors' work habits, decisions, and potential sources of conflict of interest.

Background And Objectives: Editors of scientific journals play a key role in the health-related research process. Our study aims to characterize the demographics, work habits, decision-making processes, and ethical challenges faced by editors of neurological journals and to evaluate associations between editor or journal characteristics and editorial decisions, as well as sources of conflict of interest.

Methods: Cross-sectional study involving editors from neurological journals that fell above the 50th percentile in the Scimago rankings.

The diagnostic journey of patients being investigated for myopathy in a tertiary centre in England.

Myopathies are heterogenous and can provide a diagnostic puzzle. Many patients investigated for myopathy will go on to other diagnoses. An overall understanding of how patients are investigated for suspected myopathy is lacking.

Diagnosing primary lateral sclerosis: a clinico-pathological study.

Background:  Primary lateral sclerosis (PLS) is a rare motor neuron disease characterized by upper motor neuron degeneration, diagnosed clinically due to the absence of a (neuropathological) gold standard. Post-mortem studies, particularly TDP-43 pathology analysis, are limited.

Methods: This study reports on 5 cases in which the diagnostic criteria for PLS were met, but in which neuropathology findings showed (partially) conflicting results.

Unveiling preferences in multiple sclerosis care: insights from an Italian discrete-choice experiment with patients and healthcare professionals.

Multiple sclerosis (MS) is a chronic, inflammatory, demyelinating, neurodegenerative disease of the central nervous system, significantly impacting patients' quality of life. Understanding patient and healthcare professional (HCP) preferences for MS treatments is crucial for optimizing therapeutic strategies and improving adherence and outcomes. This Discrete-Choice Experiment (DCE) assesses preferences for various MS treatment attributes among Italian patients and HCPs.

IAPRD new consensus classification of myoclonus.

Introduction: Recent new advances in myoclonus characterization and etiology justify an update of the 40-year-old respected classification of myoclonus proposed by Marsden, Hallett, and Fahn. New advances include genetic studies and clinical neurophysiology characterization.

Methods: The IAPRD appointed an expert panel to develop a new myoclonus classification.

Electrical Interference in Clinical Practice: A Conceptual and Practical Approach.

Electrical Interference (EI: radiated electromagnetic and/or power line interference) is a common problem in clinical neurophysiology with many causes and thus various conceivable solutions. Although newer digitized electrodiagnostic (EDX) systems have markedly reduced EI issues, it remains a possible impediment in achieving high quality studies. So that the electrodiagnostic medicine consultant (EMC) can problem solve EI, this monograph details the fundamental functional concepts and terminology of electronic amplification and recording electrodes from a practical perspective.

Ultrasonographic characteristics of peripheral neuropathy in systemic lupus erythematosus.

Objective: To explore the ultrasonographic characteristics of SLE-related peripheral neuropathy (PN) using nerve ultrasound.

Methods: Patients with SLE were recruited consecutively between December 2022 and June 2023. Detailed clinical assessment and nerve ultrasound were conducted on each SLE patient and healthy control (HC) at predetermined sites of peripheral nerves.

Interictal epileptiform discharge-related BOLD responses in the default mode network and subcortical regions.

Objective: To examine the blood oxygen level-dependent (BOLD) responses in the default mode network (DMN) and subcortical regions in relation to epileptic events in scalp EEG and intracranial EEG (iEEG).

Methods: We retrospectively compared BOLD responses in the DMN and subcortical regions to interictal epileptiform discharge (IED) characteristics of the scalp and iEEG in consecutive patients with focal epilepsy. All voxels were used as the denominator to assess the positive and negative BOLD ratios in each region, and the percentage of voxels with significant activation or deactivation was assessed.

Genomic 8-oxoguanine modulates gene transcription independent of its repair by DNA glycosylases OGG1 and MUTYH.

8-oxo-7,8-dihydroguanine (OG) is one of the most abundant oxidative lesions in the genome and is associated with genome instability. Its mutagenic potential is counteracted by a concerted action of 8-oxoguanine DNA glycosylase (OGG1) and mutY homolog DNA glycosylase (MUTYH). It has been suggested that OG and its repair has epigenetic-like properties and mediates transcription, but genome-wide evidence of this interdependence is lacking.

F-Wave Features in Most Common Chinese Spinocerebellar Ataxias.

The use of F-wave study may help to gain insight into electrophysiological significance of spinocerebellar Ataxias (SCAs). Particularly, the difference of F-wave features between Chinese SCA1, SCA2 and SCA3 patients were scarcely reported. 20 SCA1, 20 SCA2, 46 SCA3 patients and 30 healthy controls underwent nerve (median, ulnar, tibial) conduction and F-wave studies, and electrophysiology parameters were compared between them.

Research Priorities for Autonomous Sensory Meridian Response: An Interdisciplinary Delphi Study.

Autonomous Sensory Meridian Response (ASMR) is a multisensory experience most often associated with feelings of relaxation and altered consciousness, elicited by stimuli which include whispering, repetitive movements, and close personal attention. Since 2015, ASMR research has grown rapidly, spanning disciplines from neuroscience to media studies but lacking a collaborative or interdisciplinary approach. To build a cohesive and connected structure for ASMR research moving forwards, a modified Delphi study was conducted with ASMR experts, practitioners, community members, and researchers from various disciplines.

Neuropathy with anti-myelin-associated glycoprotein antibodies: update on diagnosis, pathophysiology and management.

Antimyelin-associated glycoprotein (MAG) neuropathy is a rare autoimmune demyelinating peripheral neuropathy caused by IgM autoantibodies targeting MAG. The typical presentation is that of a slowly progressive, distal, length-dependent, predominantly sensory, sometimes ataxic neuropathy, frequently accompanied by upper limb tremor. Distal motor weakness may subsequently occur.

Stereoelectroencephalography (SEEG)-guided insula resections: is it "Reily" worth it?

Objective: Stereoelectroencephalography (SEEG) is widely used to characterise epileptic networks and guide resection in paediatric epilepsy surgery programmes. The insula, with its extensive connectivity with temporal and extratemporal structures, has increasingly been seen as a possible surgical target. We report our seizure outcomes after SEEG-guided resection of the insula in a paediatric cohort.

A case of acute functional hemispherotomy in a young woman with hemimegalencephaly and super-refractory status epilepticus.

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.

Sensory Entrained TMS (seTMS) enhances motor cortex excitability.

Transcranial magnetic stimulation (TMS) applied to the motor cortex has revolutionized the study of motor physiology in humans. Despite this, TMS-evoked electrophysiological responses show significant variability, due in part to inconsistencies between TMS pulse timing and ongoing brain oscillations. Variable responses to TMS limit mechanistic insights and clinical efficacy, necessitating the development of methods to precisely coordinate the timing of TMS pulses to the phase of relevant oscillatory activity.

Purmorphamine Alters Anxiety-Like Behavior and Expression of Hedgehog Cascade Components in Rat Brain after Alcohol Withdrawal.

Disturbances in the Hedgehog (Hh) signaling play an important role in dysmorphogenesis of bone tissue and central nervous system during prenatal alcohol exposure, which underlies development of fetal alcohol syndrome. The involvement of Hh proteins in the mechanisms of alcohol intake in adults remains obscure. We investigated the role of the Hh cascade in voluntary ethanol drinking and development of anxiety-like behavior (ALB) during early abstinence and assessed changes in the expression of Hh pathway components in different brain regions of male Wistar rats in a model of voluntary alcohol drinking using the intermittent access to 20% ethanol in a two-bottle choice procedure.
