OBJECTIVE: The biological behavior of Cerebral Cavernous Malformation (CCM) is still controversial, lacking a clear-cut signature for a mechanistic explanation of lesion aggressiveness. In this study, we evaluated the predictive capacity of genetic variants concerning the aggressive behavior of CCM and their implications in biological processes. METHODS: We genotyped the variants in VDRrs7975232 , VDRrs731236 , VDRrs11568820 , PTPN2rs72872125 and FCGR2Ars1801274 genes using TaqMan Genotyping Assays in a cohort study with 103 patients, 42 of whom had close follow-up visits for 4 years, focusing on 2 main aspects of the disease: (1) symptomatic events, which included both intracranial bleeding or epilepsy, and (2) the onset of symptoms...

Mild malformation of cortical development with oligodendroglial hyperplasia in epilepsy (MOGHE) is an important cause of drug-resistant epilepsy. A significant subset of individuals diagnosed with MOGHE display somatic mosaicism for loss-of-function variants in SLC35A2, which encodes the UDP-galactose transporter. We developed a mouse model to investigate how disruption of this transporter leads to a malformation of cortical development. We used in utero electroporation and CRISPR/Cas9 to knockout Slc35a2 in a subset of layer 2/3 cortical neuronal progenitors in the developing brains of male and female fetal mice to model mosaic expression...

Thyroid-stimulating hormone (TSH) is a pituitary hormone that stimulates the thyroid gland to produce and release thyroid hormones, primarily thyroxine and triiodothyronine. These hormones are key players in body-brain communication, influencing various physiological processes, including the regulation of metabolism (both peripheral and central effects), feedback mechanisms, and lipid metabolism. Recently, the increasing incidence of abnormal lipid metabolism has highlighted the link between thyroid function and lipid metabolism...

The 2 most known cannabinoids are Δ9-tetrahydrocannabidiol (THC) and cannabidiol (CBD). Both chemicals are extracted from the cannabis plant but can also be synthetically produced. Δ9-Tetrahydrocannabidiol is extracted from the subspecies of the cannabis plant known as the marijuana plant, which contains a high concentration of THC (0.3% to 30%). Δ9-Tetrahydrocannabidiol is a major psychoactive and intoxicating component of the cannabis plant and is not recommended for use in dogs due to its toxic effect...

Mental health stigma remains a major global problem associated with low self-esteem, social withdrawal, and poor health-seeking behavior in individuals. However, limited published evidence details these challenges in Liberia. Knowledge of public perceptions toward mental illness and key trends in the associations between knowledge of mental, neurological, and substance use disorders (MNSs) and stigma is crucial to designing evidence-based mental health policies and supporting service delivery. This population-representative survey explored and quantified stigma related to MNSs in four health regions in Liberia, using a multistage stratified random sampling of 1,148 residents...

Sleep deprivation has been studied as a method to induce sleep before EEG testing to improve the diagnosis of epilepsy. However, the effectiveness of sleep deprivation in diagnosing epilepsy through EEG in humans showed conflicting findings in previous studies. This meta-analysis aimed to provide statistical evidence for the diagnostic value of sleep-deprived EEG in epilepsy. A systematic search of the Web of Science and PubMed databases identified 12 relevant studies from May 1997 to the present. These studies were included to examine the diagnostic value of sleep-deprived EEG in epilepsy and its associated clinical variables, such as patient age, duration of sleep deprivation, and EEG recording duration...

UNLABELLED: The WFN Needs Registry survey was developed and conducted over two and a half years commencing in 2020 to investigate the accessibility and affordability of neurological services and therapeutics and the most urgent needs. METHOD: An experienced neurologist responded in each of 118 societies to an online electronic survey comprising 13 questions. General data sought comprised the respondent's training, place of practice, duration in practice, number of neurologists in the society, health care system and types of neurological practice available...

Epilepsy, a chronic non-communicable disease of the brain, is one of the most common neurological diseases globally that affects people of all ages. The existence of medical, neurological, psychiatric, and cognitive comorbidities has always undermined the available advanced treatment strategies for epilepsy. New-generation antiepileptic drugs being less successful in completely controlling the seizures and observance of complex diseases, including drug-resistant cases, have provided scope for integrating and incorporating the therapeutic modalities of Ayurveda, the ancient Indian art of holistic medicine, in the effective management of epilepsy...

PURPOSE: To analyze the characteristics of cerebral blood flow changes of poor sleep quality in people with epilepsy(PWE). METHODS: 90 PWE treated in The General Hospital of Ningxia Medical University from December 2021 to September 2023 were divided into poor sleep quality group (PSQG) and good sleep quality group (GSQG) according to the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI), to compare the differences in cerebral perfusion between the two groups of patients, so as to summarize the characteristics of cerebral blood flow changes of poor sleep quality in PWE...

Graphogenic, or writing epilepsy, is a rare type of reflex epilepsy (RE) in which seizures are provoked by the act of writing. RE is a condition that affects between 4% and 7% of all patients diagnosed with epilepsy. In this case study, we provide a case report on a patient whose seizures were generated by the act of writing. We also present evidence that the cortical mechanisms by which writing-induced seizures occur are focal with possible secondary generalization.

We report on an 11 year old Polish girl who experienced paroxysmal episodes with decreased consciousness, (hemi)plegia, movement disorders, slurred speech, dysphagia, and abnormal eye movements. An extensive etiological work-up (brain MRI, EEG, EMG, NCS, toxic, metabolic, infectious, and auto-immune screening) was not conclusive. A genetic analysis with whole-exome sequencing demonstrated a de novo heterozygous mutation in the ATP1A3 gene (c.2232C>G, p.Asn744Lys). A 48 h video-EEG monitoring that was conducted in our unit later confirmed the absence of ictal discharge during an episode of hemidystonia, demonstrating its non-epileptic etiology...

The neuropeptide neurotensin can reduce status epilepticus and its associated consequences through induction of therapeutic hypothermia when bound to a molecule that can penetrate the blood-brain barrier.

OBJECTIVE: Epileptic seizures occur frequently after stroke due to changes in brain function and structure, and up to around 10% of stroke patients experience stroke recurrence in the first year. We aimed to establish the risk of acute symptomatic seizures in patients with recurrent stroke. METHODS: Retrospective cohort study including consecutive admissions to a Stroke Unit due to acute ischemic stroke, during a 5-year period. Additional inclusion of patients admitted to two centers in different countries to corroborate findings (confirmatory cohort)...

OBJECTIVE: The SeLECT 2.0 score is a prognostic model of epilepsy after ischemic stroke. We explored whether replacing the severity of stroke at admission with the severity of stroke after treatment at 72 h from onset could improve the predictive accuracy of the score. METHODS: We retrospectively identified consecutive adults with acute first-ever neuroimaging-confirmed ischemic stroke who were admitted to the Stroke Unit of the Ospedale Civile Baggiovara (Modena, Italy) and treated with intravenous thrombolysis and/or endovascular treatment...

OBJECTIVE: Despite recommendations to initiate antiseizure medication treatment once the diagnosis of epilepsy is confirmed, a certain proportion of patients with epilepsy who should receive antiseizure medication treatment remain untreated. We aimed to evaluate the rate of and the reasons for the treatment gap in patients with epilepsy who were referred to their first visit in our epilepsy clinic. METHODS: We retrospectively reviewed the computerized database and the medical records of all the patients with epilepsy who had their first visit in our outpatient epilepsy clinic during a 10-year period (2012-2021)...

OBJECTIVE: Very few publications have reported the impact of artisanal cannabis use on overall quality of life among people with drug-resistant epilepsy. This study aimed to evaluate the association of artisanal cannabis use among adults with drug-resistant epilepsy with quality of life, and to determine if an association exists between Quality-of-Life in Epilepsy Inventory-31 (QOLIE-31) 'T scores' and different clinical variables. METHODS: This study included patients admitted to a Canadian tertiary care epilepsy center as part of a larger study...

Temporal Lobe Epilepsy (TLE) is a severe neurological condition characterized by recurrent seizures that often do not respond well to available anti-seizure medications. TLE has been associated with epileptogenesis, a process that starts during the latent period following a neurologic insult and is followed by chronic phase. Recent research has linked canonical Wnt signaling to the pathophysiology of epileptogenesis and TLE. Our previous study demonstrated differential regulation of canonical Wnt signaling during early and late stage post status epilepticus (SE) induction...

Epilepsy which is a chronic neurological disorder is characterized by recurrent seizure poses a significant challenge to healthcare professionals worldwide. Most of antiepileptic drugs have serious side effects that might affect the quality of life such as fatigue, dizziness, weight gain and cognitive impairments. In this context, the search for more effective and potential antiepileptic drug candidate has led to a growing interest in the field of synthesis of heterocyclic compounds. This review will focus on the utilization of heterocyclic moieties including imidazole, indole, thiazole, triazine, quinazoline and oxazole which show remarkable anticonvulsant properties...
