Generalized absence seizures: Where do we stand today? (2022)

Abstract Generalized absence seizures are discussed here with respect to changing scientific concepts and newer findings, challenging the strict dichotomy of “generalized” vs. “focal” which may be counterproductive to the development of new ideas and treatments. Data from semiology, structural, and functional studies using quantitative electroencephalography (EEG), video-EEG monitoring, magnetoencephalography, magnetic resonance imaging, and positron emission tomography as well as neuropathology

Reactive, Adult Neurogenesis From Increased Neural Progenitor Cell Proliferation Following Alcohol Dependence in Female Rats (2021)

Hippocampal neurodegeneration is a consequence of excessive alcohol drinking in alcohol use disorders (AUDs), however, recent studies suggest that females may be more susceptible to alcohol-induced brain damage. Adult hippocampal neurogenesis is now well accepted to contribute to hippocampal integrity and is known to be affected by alcohol in humans as well as in animal models of AUDs. In male rats, a reactive increase in adult hippocampal neurogenesis has been observed during abstinence from al

Incidence and Types of Cardiac Arrhythmias in the Peri-Ictal Period in Patients Having a Generalized Convulsive Seizure (2024)

Markers of seizure severity are not related to seizure-induced arrhythmias of interest, suggesting that other factors such as occult cardiac abnormalities may be relevant for their occurrence. Seizure-induced ESAWB and bradycardia were more frequent in SUDEP cases, although this observation was based on a very limited number of SUDEP patients. Further case-control studies are needed to evaluate the yield of arrhythmias of interest along with respiratory changes as potential SUDEP biomarkers.

Impact of TRPV1 on Pathogenesis and Therapy of Neurodegenerative Diseases (2023)

Transient receptor potential vanilloid 1 (TRPV1) is a transmembrane and non-selective cation channel protein, which can be activated by various physical and chemical stimuli. Recent studies have shown the strong pathogenetic associations of TRPV1 with neurodegenerative diseases (NDs), in particular Alzheimer's disease (AD), Parkinson's disease (PD) and multiple sclerosis (MS) via regulating neuroinflammation. Therapeutic effects of TRPV1 agonists and antagonists on the treatment of AD and PD in

Current Perspectives on the Challenges of Implementing Assistance Dogs in Human Mental Health Care (2023)

The prevalence of mental health disorders, driven by current global crises, is notably high. During the past decades, the popularity of dogs assisting humans with a wide spectrum of mental health disorders has significantly increased. Notwithstanding these dogs' doubtless value, research on their legal status, certification processes, training and management practices, as well as their welfare status, has been scarce. This scoping review highlights that in contrast to other assistance dogs such

Novel methods for the remote investigation of emerging substances: Application to kratom. (2023)

The botanical product commonly called "kratom" is still relatively novel to the United States. Like other natural products marketed as supplements, kratom is highly variable, both in terms of the alkaloids naturally occurring in kratom leaves and in terms of processing and formulation. Kratom products sold in the United States are not well-characterized, nor are daily use patterns among regular users. Surveys and case reports have comprised most of the literature on kratom use among humans. To a

A draft conceptual model of SLC6A1 neurodevelopmental disorder (2023)

For rare diseases, analysis of published literature is important, but may not be as comprehensive as that which can be gleaned from spontaneous interactions between families and through qualitative interviews. This report reflects our current understanding of the lived experience of SLC6A1-NDD. The discrepancy between the domains of disease reported in the literature and those discussed in patient conversations suggests that a formal qualitative interview-based disease concept study of SLC6A1-ND

Combinatorial Regimen of Carbamazepine and Imipramine Exhibits Synergism against Grandmal Epilepsy in Rats: Inhibition of Pro-Inflammatory Cytokines and PI3K/Akt/mTOR Signaling Pathway (2021)

Epilepsy is a neurodegenerative disorder that causes recurring seizures. Thirty-five percent of patients remain refractory, with a higher prevalence of depression. We investigated the anticonvulsant efficacy of carbamazepine (CBZ; 20 and 50 mg/kg), imipramine (IMI; 10 and 20 mg/kg) alone, and as a low dose combination. This preclinical investigation included dosing of rats for 14 days followed by elicitation of electroshock on the last day of treatment. Along with behavioral monitoring, the rat

Do All Roads Lead to Rome? Genes Causing Dravet Syndrome and Dravet Syndrome-Like Phenotypes (2022)

DS is not only identified in variants of <i>SCN1A</i>, but other genes such as <i>PCDH19, SCN2A, SCN8A, SCN1B, GABRA1, GABRB3, GABRG2, KCNA2, CHD2, CPLX1, HCN1A, STXBP1</i> can also be involved in DS or DS-like phenotypes. As genetic testing becomes more widely available, more genes associated with DS and DS-like phenotypes may be identified and gene-based diagnosis of subtypes of phenotypes in this spectrum may improve the management of these diseases in the future.

Contribution of Altered Endocannabinoid System to Overactive mTORC1 Signaling in Focal Cortical Dysplasia (2019)

Alterations of the PI3K/Akt/mammalian target of rapamycin complex 1 (mTORC1) signaling pathway are causally involved in a subset of malformations of cortical development (MCDs) ranging from focal cortical dysplasia (FCD) to hemimegalencephaly and megalencephaly. These MCDs represent a frequent cause of refractory pediatric epilepsy. The endocannabinoid system -especially cannabinoid CB<sub>1</sub> receptor- exerts a neurodevelopmental regulatory role at least in part via activation of mTORC1 sig

Transient receptor potential vanilloid (TRPV) channels: Basal properties and physiological potential (2022)

Transient receptor potential vanilloid (TRPV) channels are TRP homologs and have been classified into six subfamilies. They are unique mediators of sensory signals with multiple physiological effects and are potential targets for developing new therapies targeting human diseases. TRPV channels play crucial roles in normal physiological processes, and their dysfunction has been implicated in various disease states. Several small-molecule compounds, such as TRPV1 and TRPV3 antagonists, have been d

Drug-drug interactions between antiepileptics and cannabinoids (2019)

Introduction: About 40% of patients with epilepsy are associated with drug-resistant seizures, therefore there has been a continuous search for novel treatment approaches. In experimental studies, natural and synthetic cannabimimetic compounds alone or combined with antiepileptic drugs (AEDs) have been extensively studied and cannabidiol, a naturally occurring compound, has been involved in a number of clinical trials.Areas covered: The authors have performed a literature search (PubMed database

Status epilepticus: review on diagnosis, monitoring and treatment (2022)

Status epilepticus (SE) is a frequent neurological emergency associated with high morbidity and mortality. According to the new ILAE 2015 definition, SE results either from the failure of the mechanisms responsible for seizure termination or initiation, leading to abnormally prolonged seizures. The definition has different time points for convulsive, focal and absence SE. Time is brain. There are changes in synaptic receptors leading to a more proconvulsant state and increased risk of brain lesi

Treatment-Resistant Epilepsy and Tuberous Sclerosis Complex: Treatment, Maintenance, and Future Directions (2023)

Tuberous sclerosis complex (TSC) is a neurogenetic disorder that affects multiple organ systems, including the heart, kidneys, eyes, skin, and central nervous system. The neurologic manifestations have the highest morbidity and mortality, in particular in children. Clinically, patients with TSC often present with new-onset seizures within the first year of life. TSC-associated epilepsy is often difficult to treat and refractory to multiple antiseizure medications. Refractory TSC-associated epile

Biomedical Perspectives of Citronellal: Biological Activities, Toxicological Profile and Molecular Mechanisms (2024)

Citronellal, known as rhodinal, is a naturally occurring monoterpenoid aldehyde distinctly found in the distilled oils of Cymbopogon species including C. marginatus, C. citratus, C. validus and C. winterianus family Gramineae. It is also obtained from eucalyptus, mentha, melissa, cinnamomum and allium. It is traditionally used in air freshener, cleaner, floor polishing, deodorants, moisturizing hand/body lotion, perfumes, and adhesives due to its lemon characteristic fragrance and therapeutic be
