Risk of vigabatrin-associated brain abnormalities on MRI in the treatment of infantile spasms is dose-dependent

Summary

Objective

Although the link between vigabatrin (VGB) and retinotoxicity is well known, little attention has been focused on the risk of VGB-associated brain abnormalities on magnetic resonance imaging (MRI) (VABAM), namely reversible—and largely asymptomatic—signal changes in the thalami, basal ganglia, brainstem tegmentum, and cerebellar nuclei. Using a large infantile spasms cohort, we set out to identify predictors of these phenomena.

Methods

Children with infantile spasms were retrospectively identified. Brain MRI reports were serially reviewed without knowledge of VGB exposure. ...

Resistance to valproic acid as predictor of treatment resistance in genetic generalized epilepsies

Summary

This study aimed at defining clinical predictors of drug resistance in adults with genetic generalized epilepsy (GGE) who were treated with a broad spectrum of antiepileptic drugs. Of a cohort of 137 unselected adult GGE patients with long-term follow up, clinical and demographic data, putative prognostic factors (e.g., psychiatric comorbidities, electroencephalography [EEG]), treatment response, and data indicative of social status were collected. Fifty-eight patients had seizures within the past year. Thirty-three patients met the definition of “drug-resistant ...

Randomized, double-blind, placebo-controlled phase 2 study of ganaxolone as add-on therapy in adults with uncontrolled partial-onset seizures

Summary

Objective

To evaluate the efficacy and safety of ganaxolone as adjunctive therapy in adults with uncontrolled partial-onset seizures despite taking up to three concomitant antiepileptic drugs (AEDs).

Methods

Adults aged 18–69 years and refractory to conventional AEDs were enrolled in a multicenter, double-blind, placebo-controlled trial. After an 8-week baseline period, patients were randomized 2:1 to ganaxolone 1,500 mg/day or placebo for a 10-week treatment period (2-week forced titration and 8-week maintenance) followed by either tapering or entry into an open-label extension ...

Modified Atkins diet is an effective treatment for children with Doose syndrome

Summary

Objective

Children with myoclonic astatic epilepsy (MAE; Doose syndrome) whose seizures do not respond immediately to standard antiepileptic drugs (AEDs) are at high risk of developing an epileptic encephalopathy with cognitive decline. A classic ketogenic diet (KD) is a highly effective alternative to AEDs. To date, there are only limited data on the effectiveness of the modified Atkins diet (MAD), which is less restrictive and more compatible with daily life. We report findings from a retrospective study on ...

Presurgical language localization with visual naming associated ECoG high- gamma modulation in pediatric drug-resistant epilepsy

Summary

Objective

This prospective study compared presurgical language localization with visual naming–associated high-γ modulation (HGM) and conventional electrical cortical stimulation (ECS) in children with intracranial electrodes.

Methods

Patients with drug-resistant epilepsy who were undergoing intracranial monitoring were included if able to name pictures. Electrocorticography (ECoG) signals were recorded during picture naming (overt and covert) and quiet baseline. For each electrode the likelihood of high-γ (70–116 Hz) power modulation during naming task relative to the baseline was estimated. Electrodes with significant HGM ...
