Reactivation of seizure-related changes to interictal spike shape and synchrony during postseizure sleep in patients

Summary

Objective

Local field potentials (LFPs) arise from synchronous activation of millions of neurons, producing seemingly consistent waveform shapes and relative synchrony across electrodes. Interictal spikes (IISs) are LFPs associated with epilepsy that are commonly used to guide surgical resection. Recently, changes in neuronal firing patterns observed in the minutes preceding seizure onset were found to be reactivated during postseizure sleep, a process called seizure-related consolidation (SRC), due to similarities with learning-related consolidation. Because IISs arise from summed neural ...

Duration of use of oral cannabis extract in a cohort of pediatric epilepsy patients

Summary

Objective

Oral cannabis extracts (OCEs) are being used in the treatment of epilepsy with increasing rates in the United States following product legalization; however, no studies demonstrate clear efficacy. We evaluated the duration of use of OCEs as a measure of perceived benefit in a cohort of patients with pediatric epilepsy.

Methods

Retrospective chart review was performed of children and adolescents who were given OCEs for treatment of epilepsy.

Results

Of the 119 patients included in the analysis, 71% terminated ...

Temporal lobe epilepsy and focal cortical dysplasia in children: A tip to find the abnormality

Summary

Objective

To demonstrate an association between magnetic resonance imaging (MRI) findings and pathologic characteristics in children who had surgery for medically refractory epilepsy due to focal cortical dysplasia (FCD).

Methods

We retrospectively studied 110 children who had epilepsy surgery. Twenty-seven patients with FCD were included. Thirteen had temporal lobe epilepsy (TLE) and 14 had extra-temporal lobe epilepsy (ETLE). Three patients had associated mesial temporal sclerosis. Preoperative 3T MRIs interleaved with nine controls were blindly re-reviewed and categorized according to ...

Long-term monitoring of cardiorespiratory patterns in drug-resistant epilepsy

Summary

Objective

Sudden unexplained death in epilepsy (SUDEP) during inpatient electroencephalography (EEG) monitoring has been a rare but potentially preventable event, with associated cardiopulmonary markers. To date, no systematic evaluation of alarm settings for a continuous pulse oximeter (SpO2) has been performed. In addition, evaluation of the interrelationship between the ictal and interictal states for cardiopulmonary measures has not been reported.

Methods

Patients with epilepsy were monitored using video-EEG, SpO2, and electrocardiography (ECG). Alarm thresholds were tested systematically, balancing the ...
