BACKGROUND Topiramate (TPM), a broad-spectrum antiepileptic drug, has been associated with neuropsychological impairment in patients with epilepsy and in healthy volunteers. OBJECTIVE To establish whether TPM-induced neuropsychological impairment emerges in a dose-dependent fashion and whether early cognitive response (6-week) predicts later performance(More)
BACKGROUND The purpose of this study was to assess the efficacy and safety and to explore the dose response of esketamine intravenous (IV) infusion in patients with treatment-resistant depression (TRD). METHODS This multicenter, randomized, placebo-controlled trial was conducted in 30 patients with TRD. Patients were randomly assigned 1:1:1 to receive an(More)
This 24-week, multicenter, open-label trial was designed to evaluate the dosing, effectiveness, and safety of topiramate monotherapy for epilepsy and to identify patient and clinical characteristics predictive of optimally effective stabilized monotherapy doses. Of 406 randomized patients, 244 comprised the evaluable-for-efficacy population (12 weeks of(More)
We applied serial analysis of gene expression (SAGE) to study differentially expressed genes in mouse brain 14 hr after the induction of focal cerebral ischemia. Analysis of >60,000 transcripts revealed 83 upregulated and 94 downregulated transcripts (more than or equal to eightfold). Reproducibility was demonstrated by performing SAGE in duplicate on the(More)
Placebo and pharmacodynamic (PD) models were developed which link temporal measures of efficacy in children with attention deficit hyperactivity disorder (ADHD) and methylphenidate (MPH) plasma concentrations from adults. These models can be used to predict daily pediatric clinical measure profiles following administration of different MPH formulations in(More)
Historical document collections present unique challenges for information retrieval. In particular, the absence of consistent orthographic conventions in historical text presents difficulties for conventional search architectures which typically rely on a static inverted index keyed by orthographic form. Additional steps must therefore be taken in order to(More)
OBJECTIVE Evaluate the antiepileptic effect of topiramate monotherapy in childhood absence epilepsy (CAE). MATERIALS AND METHODS Childhood absence epilepsy patients aged 4-9 years were initiated with topiramate 15 or 25 mg/day, which was titrated upwards until patients were free of absence seizures. The primary efficacy outcome was seizure-free rates(More)

Adverse cognitive effects are an important concern for drugs that influence the central nervous system. Carisbamate is a novel drug in development for treatment of seizures and neuropathic pain. Information on its cognitive effects is limited. Three controlled, multiple-dose, crossover studies with treatment durations of 5-9 days were designed to examine(More)
