Insulo-opercular cortex generates oroalimentary automatisms in temporal seizures

Summary

Objective

Oroalimentary automatisms (OAAs) resembling normal alimentary behavior are stereotyped complex movements that may occur during epileptic seizures. They are considered common clinical signs in temporal lobe seizures, but their anatomofunctional mechanisms are not established. We took the opportunity of presurgical intracerebral recordings to study the relations between the occurrence of OAAs and temporal/spatial features of ictal activities.

Methods

We retrospectively reviewed patients with medically intractable medial temporal lobe epilepsy who underwent stereoelectroencephalography (SEEG) at Cleveland Clinic between 2009 ...

Laser ablation is effective for temporal lobe epilepsy with and without mesial temporal sclerosis if hippocampal seizure onsets are localized by stereoelectroencephalography

Summary

Objective

Selective laser amygdalohippocampotomy (SLAH) using magnetic resonance–guided laser interstitial thermal therapy (MRgLITT) is emerging as a treatment option for drug-resistant mesial temporal lobe epilepsy (MTLE). SLAH is less invasive than open resection, but there are limited series reporting its safety and efficacy, particularly in patients without clear evidence of mesial temporal sclerosis (MTS).

Methods

We report seizure outcomes and complications in our first 30 patients who underwent SLAH for drug-resistant MTLE between January 2013 and December 2016. We ...

Frontal lobe epileptic seizures are accompanied by elevated pitch during verbal communication

Summary

The objective of our study was to assess alterations in speech as a possible localizing sign in frontal lobe epilepsy. Ictal speech was analyzed in 18 patients with frontal lobe epilepsy (FLE) during seizures and in the interictal period. Matched identical words were analyzed regarding alterations in fundamental frequency (ƒo) as an approximation of pitch. In patients with FLE, ƒo of ictal utterances was significantly higher than ƒo in interictal recordings (p = 0.016). Ictal ƒo increases ...

Topographic principles of cortical fluid-attenuated inversion recovery signal in temporal lobe epilepsy

Summary

Objective

In drug-resistant temporal lobe epilepsy (TLE), relative to the large number of whole-brain morphological studies, neocortical T2 changes have not been systematically investigated. The aim of this study was to assess the anatomical principles that govern the distribution of neocortical T2-weighted fluid-attenuated inversion recovery (FLAIR) signal intensity and uncover its topographic principles.

Methods

Using a surface-based sampling scheme, we mapped neocortical FLAIR intensity of 61 TLE patients relative to 38 healthy controls imaged at 3 T. To address ...

Development and assessment of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-16)

Summary

Objective

The aim of this study was to develop and validate a brief version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). A secondary aim was to compare the results described in previously published studies using the QOLCE-55 with those obtained using the new brief version.

Methods

Data come from 373 children involved in the Health-related Quality of Life in Children with Epilepsy Study, a multicenter prospective cohort study. Item response theory (IRT) methods were used to ...

Delayed myelination and neurodevelopment in male seizure-prone versus seizure-resistant rats

Summary

Objective

Aberrant myelination and developmental delay have been reported in epilepsy. However, it is unclear whether these are linked to intrinsic mechanisms that support a predisposition toward seizures and the development of epilepsy. Thus, we compared rates of myelination and neurodevelopment in male rats selectively bred for enhanced susceptibility to kindling epileptogenesis (FAST) with male rats bred for resistance (SLOW).

Methods

Myelin-specific gene expression was compared in the brainstem, cerebellum, and cerebral hemisphere of FAST and SLOW rats on ...

PCDH19-related epilepsy is associated with a broad neurodevelopmental spectrum

Summary

Objective

To characterize the features associated with PCDH19-related epilepsy, also known as “female-limited epilepsy.”

Methods

We analyzed data from participants enrolled in the PCDH19 Registry, focusing on the seizure-related, developmental, neurobehavioral, and sleep-related features. We evaluated variants for pathogenicity based on previous reports, population databases, and in silico predictions, and included individuals with pathogenic or potentially pathogenic variants. We performed a retrospective analysis of medical records and administered a targeted questionnaire to characterize current or past features in probands ...
