Magnetic resonance imaging connectivity for the prediction of seizure outcome in temporal lobe epilepsy

Summary

Objective

Currently, approximately 60–70% of patients with unilateral temporal lobe epilepsy (TLE) remain seizure-free 3 years after surgery. The goal of this work was to develop a presurgical connectivity-based biomarker to identify those patients who will have an unfavorable seizure outcome 1-year postsurgery.

Methods

Resting-state functional and diffusion-weighted 3T magnetic resonance imaging (MRI) was acquired from 22 unilateral (15 right, 7 left) patients with TLE and 35 healthy controls. A seizure propagation network was identified including ipsilateral (to seizure ...

The epileptology of Koolen-de Vries syndrome: Electro-clinico-radiologic findings in 31 patients

Summary

Objective

This study was designed to describe the spectrum of epilepsy phenotypes in Koolen-de Vries syndrome (KdVS), a genetic syndrome involving dysmorphic features, intellectual disability, hypotonia, and congenital malformations, that occurs secondary to 17q21.31 microdeletions and heterozygous mutations in KANSL1.

Methods

We were invited to attend a large gathering of individuals with KdVS and their families. While there, we recruited individuals with KdVS and seizures, and performed thorough phenotyping. Additional subjects were included who approached us after the family ...

Heart-rate variability indices as predictors of the response to vagus nerve stimulation in patients with drug-resistant epilepsy

Summary

Objective

To assess heart-rate variability (HRV) measures of interictal electrocardiography (ECG) for drug-resistant epilepsy and to relate the findings to the outcome of vagus nerve stimulation (VNS) treatment.

Methods

Time-domain, frequency-domain, and nonlinear analyses were used to analyze preoperative HRV measures in 32 patients with drug-resistant epilepsy who had received VNS implants at the same hospital and 32 healthy age- and sex-matched control subjects. HRV measurements based on ambulatory 24 h ECG recordings were analyzed to identify seizure reduction 1 year ...

Length of stay for patients undergoing invasive electrode monitoring with stereoelectroencephalography and subdural grids correlates positively with increased institutional profitability

Summary

Objective

Lowering the length of stay (LOS) is thought to potentially decrease hospital costs and is a metric commonly used to manage capacity. Patients with epilepsy undergoing intracranial electrode monitoring may have longer LOS because the time to seizure is difficult to predict or control. This study investigates the effect of economic implications of increased LOS in patients undergoing invasive electrode monitoring for epilepsy.

Methods

We retrospectively collected and analyzed patient data for 76 patients who underwent invasive monitoring ...

Stress is associated with an increased risk of recurrent seizures in adults

Summary

Objective

The literature is sparse on the complex interrelationships between stressors, depression, anxiety disorders, and epilepsy. We hypothesized that a relationship exists between stress and epilepsy. We evaluated whether markers of stress are associated with seizure recurrence in a low income community-based cohort of adults with single unprovoked seizure or newly diagnosed epilepsy.

Methods

We ascertained adult residents of Northern Manhattan and Harlem, New York City, with a first unprovoked seizure or newly diagnosed epilepsy, between December 2010 and ...

Auditory processing following infantile spasms: An event-related potential study

Summary

Objectives

To investigate acoustic auditory processing in patients with recent infantile spasms (IS).

Methods

Patients (n = 22; 12 female; median age 8 months; range 5–11 months) had normal preceding development, brain magnetic resonance imaging (MRI), and neurometabolic testing (West syndrome of unknown cause, uWS). Controls were healthy babies (n = 22; 11 female; median age 6 months; range 3–12 months). Event-related potentials (ERPs) and psychometry (Bayley Scales of Infant Development, Second Edition, BSID-II) took place at a month ...

Early discontinuation of antiseizure medications in neonates with hypoxic–ischemic encephalopathy

Summary

Objective

Neonates with hypoxic–ischemic encephalopathy (HIE) managed with therapeutic hypothermia (TH) often experience acute symptomatic seizures, prompting treatment with antiseizure medications (ASMs). Because the risk of seizure occurrence after hospital discharge is unknown, the optimal ASM treatment duration is unclear. We aimed to determine the risk of seizure occurrence after hospital discharge and the impact of ASM treatment duration on this outcome.

Methods

We performed a single-center, retrospective study of consecutive neonates with HIE managed with TH who received ...
