BACKGROUND: Valproate is a broad-spectrum anticonvulsant that is effective in the treatment of tonic-clonic, myoclonic and absence seizures as well as in partial seizures as a second-line drug. It has been widely demonstrated in the literature that the effect of valproate on type-A γ-aminobutyric acid (GABA-A) receptors may reduce relapse to ethanol abuse. This retrospective study evaluated a 3-year period in which 42 patients from the Department of Alcoholism and Substance Abuse (DASA) were treated with valproate...

STUDY OBJECTIVE: Seizures account for 1.2% of all emergency department (ED) visits, with 24% of those representing first-time seizures. Our primary goal is to determine whether obtaining an electroencephalogram (EEG) in the ED after a first-time seizure can identify individuals appropriate for initiation of anticonvulsant therapy on ED discharge. Our secondary goals are to determine the association of historical and clinical seizure features with epileptic EEGs and to determine the interobserver agreement for the EEG interpretation...

Temporal lobe epilepsy (TLE) is one of the most refractory types of adult epilepsy, and treatment options remain unsatisfactory. Gastrodin (GAS), a phenolic glucoside used in Chinese herbal medicine and derived from Gastrodia elata Blume, has been shown to have remarkable anticonvulsant effects on various models of epilepsy in vivo. However, the mechanisms of GAS as an anticonvulsant drug remain to be established. By utilizing a combination of behavioral surveys, immunofluorescence and electrophysiological recordings, the present study characterized the anticonvulsant effect of GAS in a pilocarpine-induced status epilepticus (SE) rat model of TLE and explored the underlying cellular mechanisms...

Drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is a rare and severe side-effect, mainly described after intake of anticonvulsants, allopurinol, or antibiotics. It usually begins within 2 months after drug introduction. Symptoms include cutaneous rash, hematologic abnormalities, and internal organ involvement and the diagnosis might be challenging. This case report illustrates for the first time this life-threatening complication in a patient with cystic fibrosis (CF). In this case, withdrawal of the offending drug was sufficient for full recovery...

OBJECTIVE: Infection with Theiler's murine encephalomyelitis virus (TMEV) in C57Bl/6J mice induces acute seizures and development of spontaneous recurrent seizures and behavioral comorbidities weeks later. The present studies sought to determine whether acute therapeutic intervention with an anti-inflammatory-based approach could prevent or modify development of TMEV-induced long-term behavioral comorbidities. Valproic acid (VPA), in addition to its prototypical anticonvulsant properties, inhibits histone deacetylase (HDAC) activity, which may alter expression of the inflammasome...

OBJECTIVES: The clock gene ARNTL is associated with the transcription activation of monoamine oxidase A according to previous literature. Thus, we hypothesised that methylation of ARNTL may differ between bipolar disorder (BD) and controls. METHODS: The methylation status of one CpG island covering the first exon of ARNTL (PS2) and one site in the 5' region of ARNTL (cg05733463) were analysed in patients with BD (n = 151) versus controls (n = 66). Methylation analysis was performed by bisulphite-conversion of DNA from fasting blood with the EpiTect Bisulfite Kit, PCR and pyrosequencing...

Sciatica is a debilitating condition affecting approximately 25 % of the population. Typically, the patient will complain of lower limb pain that is more severe than pain in the lower back, usually accompanied by numbness and motor weakness. Most international guidelines recommend pharmacological management for the pain relief of sciatica, including paracetamol, non-steroidal anti-inflammatory drugs, opioid analgesics, anticonvulsants, and corticosteroids, among others. However, the evidence for most of these pharmacological options is scarce, and the majority of clinical trials exclude older patients...

Enhancement of neuronal M-currents, generated through KV7.2-KV7.5 channels, has gained much interest for its potential in developing treatments for hyperexcitability-related disorders such as epilepsy. Retigabine, a KV7 channel opener, has proven to be an effective anticonvulsant and has recently also gained attention due to its neuroprotective properties. In the present study, we found that the auxiliary KCNE2 subunit reduced the KV7.2-KV7.3 retigabine sensitivity approximately 5-fold. In addition, using both mammalian expression systems and cultured hippocampal neurons we determined that low μM retigabine concentrations had 'off-target' effects on KV2...

Some anticonvulsant drugs are associated with cognitive ability in patients; Topiramate (TPM) is well known as an effective anticonvulsant agent applied in clinical settings. However, the effect of TPM on the cognitive function is rarely studied. In this study, we aimed to observe the effects of TPM on cell proliferation and neuronal differentiation in the dentate gyrus (DG) of the D-galactose-induced aging mice by Ki-67 and doublecortin (DCX) immunohistochemistry. The study is divided into four groups including control, D-galactose-treated group, 25 and 50 mg/kg TPM-treated plus D-galactose-treated groups...
