Phytochemical Profile and in vitro and in vivo Anticonvulsant and Antioxidant Activities of Epilobium hirsutum (2020)

This study presents the phytochemical profile and in vitro and in vivo anticonvulsant and antioxidant activities of Epilobium hirsutum, which has been traditionally used in the treatment of epilepsy by local people of Turkey. In vitro studies revealed that the extract contained a pronounced amount of phenolics (206.3±0.9 mg Gallic acid Eq/g extract) and exhibited significant levels of antioxidant (FRAP; 6226 µmol Fe2+/g extract, ORAC; 6593 µmol Trolox Eq/g extract, DPPH; IC50:33.8 ug/mL and met

Spectrum, Evolution, and Clinical Relationship of Magnetic Resonance Imaging in 31 Children with Febrile Infection-Related Epilepsy Syndrome (2023)

In contrast to the uniform clinical course, MRI demonstrated a broad spectrum of findings. Initially, these were mostly normal and therefore indicative of FIRES but then changed rapidly and were mostly progressive despite the stable chronic course. The cause may be ongoing disease, treatment intensity, or both. Future studies should focus on what process underlies the onset and the progression of brain atrophy. However, brain atrophy was not always related to poor outcomes in children despite FI

Sarcosine Suppresses Epileptogenesis in Rats With Effects on Hippocampal DNA Methylation (2020)

Epileptogenesis is a common consequence of brain insults, however, the prevention or delay of the epileptogenic process remains an important unmet medical challenge. Overexpression of glycine transporter 1 (GlyT1) is proposed as a pathological hallmark in the hippocampus of patients with temporal lobe epilepsy (TLE), and we previously demonstrated in rodent epilepsy models that augmentation of glycine suppressed chronic seizures and altered acute seizure thresholds. In the present study we evalu

Adult Phenotype of SYNGAP1 -DEE (2023)

Seventy-one percent of patients with <i>SYNGAP1</i>-DEEs continue to have seizures when adults. Nonseizure comorbidities, especially aggression and self-injurious behaviors, are major management challenges in adults with <i>SYNGAP1</i>-DEE. Only 50% of adults can ambulate with minimal or no assistance. Almost all adult patients depend on caregivers for many activities of daily living. Prompt diagnostic genetic testing of adults with DEE can inform clinical care and guide outcomes of precision th

Medial prefrontal cortex oxytocin mitigates epilepsy and cognitive impairments induced by traumatic brain injury through reducing neuroinflammation in mice (2023)

Traumatic brain injury (TBI) is a major risk factor to develop epilepsy and cognitive impairments. Neuropeptide oxytocin has been previously evidenced to produce antiepileptic effects. However, the involvement of central oxytocin in TBI-induced epileptic status and cognitive dysfunctions is not fully elucidated. In this study, we aim to investigate the role of oxytocin on a TBI model followed by seizure induction to clarify whether the epilepsy and cognitive deficits could be mitigated by oxytoc

Rapamycin for longevity: the pros, the cons, and future perspectives (2025)

Rapamycin, an antibiotic discovered in the 1970s from <i>Streptomyces hygroscopicus</i> on Easter Island (Rapanui), has become a critical tool in biomedical research. Initially recognized for its potent antifungal and immunosuppressive properties, rapamycin has recently gained significant attention for anti-aging therapy and seizure treatment via mTOR pathway inhibition. The mechanistic target of the rapamycin (mTOR) pathway is an evolutionarily conserved metabolic signaling cascade that regulat

Systemic inflammation as a biomarker of seizure propensity and a target for treatment to reduce seizure propensity (2022)

People with diabetes can wear a device that measures blood glucose and delivers just the amount of insulin needed to return the glucose level to within bounds. Currently, people with epilepsy do not have access to an equivalent wearable device that measures a systemic indicator of an impending seizure and delivers a rapidly acting medication or other intervention (e.g., an electrical stimulus) to terminate or prevent a seizure. Given that seizure susceptibility is reliably increased in systemic

Cannabis-Induced Mania Following COVID-19 Self-Medication: A Wake-Up Call to Improve Community Awareness (2021)

Cannabis induced mental illness following self-medication for COVID-19 like symptoms is on the rise in the population. Due to increasing COVID-19 cases globally, hospital congestion, the popularity of home-based care guidelines for asymptomatic and mild COVID-19 to reduce hospital burden in many countries, and easy access to cannabis. With no approved cure for COVID-19, patients are turning to natural remedies to relieve symptoms of COVID-19. Emphasis on prevention of this insalubrious self-medi

Challenges and directions in epilepsy diagnostics and therapeutics: Proceedings of the 17th Epilepsy Therapies and Diagnostics Development conference (2023)

Substantial efforts are underway toward optimizing the diagnosis, monitoring, and treatment of seizures and epilepsy. We describe preclinical programs in place for screening investigational therapeutic candidates in animal models, with particular attention to identifying and eliminating drugs that might paradoxically aggravate seizure burden. After preclinical development, we discuss challenges and solutions in the design and regulatory logistics of clinical trial execution, and efforts to devel

Brain targeted lactoferrin coated lipid nanocapsules for the combined effects of apocynin and lavender essential oil in PTZ induced seizures (2024)

Apocynin (APO) is a plant derived antioxidant exerting specific NADPH oxidase inhibitory action substantiating its neuroprotective effects in various CNS disorders, including epilepsy. Due to rapid elimination and poor bioavailability, treatment with APO is challenging. Correspondingly, novel APO-loaded lipid nanocapsules (APO-LNC) were formulated and coated with lactoferrin (LF-APO-LNC) to improve br ain targetability and prolong residence time. Lavender oil (LAV) was incorporated into LNC as a

Heat-induced seizures, premature mortality, and hyperactivity in a novel Scn1a nonsense model for Dravet syndrome (2023)

Dravet syndrome (Dravet) is a severe congenital developmental genetic epilepsy caused by <i>de novo</i> mutations in the <i>SCN1A</i> gene. Nonsense mutations are found in ∼20% of the patients, and the R613X mutation was identified in multiple patients. Here we characterized the epileptic and non-epileptic phenotypes of a novel preclinical Dravet mouse model harboring the R613X nonsense <i>Scn1a</i> mutation. <i>Scn1a</i><sup><i>WT/R</i>613<i>X</i></sup> mice, on a mixed C57BL/6J:129S1/SvImJ bac

Three-Year Follow-Up after Intrauterine mTOR Inhibitor Administration for Fetus with TSC-Associated Rhabdomyoma (2023)

Tuberous sclerosis complex (TSC) is a multisystem disorder characterized by seizures, neuropsychiatric disorders, and tumors of the heart, brain, skin, lungs, and kidneys. We present a three-year follow-up of a patient with TSC-associated rhabdomyoma detected in utero. Genetic examination of the fetus and the parents revealed a de novo variant in the <i>TSC2</i> gene (c.3037delG, p.Asp1013IlefsTer3). Oral everolimus was initiated in the pregnant mother to regress the fetal tumor, which was succe

Navigating the outcome maze: a scoping review of outcomes and instruments in clinical trials in genetic neurodevelopmental disorders and intellectual disability (2024)

This scoping review of current practice reveals a myriad of outcomes and outcome measurement instruments for clinical trials in GNDs and ID. This complicates generalization, evidence synthesis, and evaluation. It underlines the need for consensus on suitability, validity, and relevancy of instruments, ultimately resulting in a core outcome set. A series of steps is proposed to move from the myriad of measures to a more unified approach.

Modeling Neurodevelopmental Disorders and Epilepsy Caused by Loss of Function ofkif2ain Zebrafish (2021)

In recent years there has been extensive research on malformations of cortical development (MCDs) that result in clinical features like developmental delay, intellectual disability, and drug-resistant epilepsy (DRE). Various studies highlighted the contribution of microtubule-associated genes (including tubulin and kinesin encoding genes) in MCD development. It has been reported that <i>de novo</i> mutations in <i>KIF2A</i>, a member of the <i>kinesin-13</i> family, are linked to brain malformat
