We have developed a semi-automated method for measuring five kinds of antiepileptic drugs in serum by successfully adapting commercial competitive-binding enzyme immunoassay kits (MARKIT; Dainippon) for use with a continuous-flow analyzer (Technicon AutoAnalyzer II equipped with a dialyzer). The free enzyme-labeled drug is automatically separated by a microfilter from the competitive immunoreaction mixture between labeled and unlabeled drug for anti-drug immunoglobulin coupled to bacterial cell walls. The concentrations of the antiepileptic drugs in serum samples can be determined by automated measurement of enzyme activity of the enzyme-labeled drugs. Results of the semi-automated method correlated well with those obtained by manual enzyme immunoassay, gas-liquid chromatography, and "high-pressure" liquid chromatography. The correlation coefficients were all greater than 0.95, showing the practicality of this method for therapeutic monitoring of antiepileptic drugs.

Epilepsy is a chronic neurological disorder caused by abnormal discharges of neurons in the brain, which seriously affects the quality of life of patients. Although there are various drug treatments available, many epilepsy patients still experience seizures with the effect of drugs and develop refractory epilepsy. The ketogenic diet can treat drug-refractory epilepsy by regulating the body's metabolism and can enhance the quality of life by improving their cognition, behavior, and sleep quality.

Seizures are a frequent complication in glioma. Incidence of brain tumor-related epilepsy (BTRE) in high-grade glioma (HGG) is an estimated > 25% and in low-grade glioma (LGG) is approximately 72%. Two first-line antiseizure medications (ASMs) for BTRE include levetiracetam (LEV) and valproic acid (VPA).

Background: Reduction of intracellular Na accumulation through late Na current inhibition has been recognized as a target for cardiac Ca handling which underlies myocardial contractility and relaxation in heart failure (HF). Riluzole, an Na channel blocker with enhancement of Ca-activated K channel function, used for management of amyotrophic lateral sclerosis (ALS), is effective in suppressing Ca leak and therefore may improve cardiac function.
Objectives: The study aim was to investigate whether riluzole lowers HF incidence.
Background: Altered network synchronization and rhythmic neural activity is observed in Alzheimer's disease (AD). Spontaneous epileptiform activity and/or seizures occur in an estimated 60% of AD cases, and having AD increases the likelihood of seizures when compared with people without dementia. Thus, network hyperexcitability can be an early feature and helpful for diagnosis and treatment.
