Deep net detection and onset prediction of electrographic seizure patterns in responsive neurostimulation

Abstract

Objective

Managing the progress of drug-resistant epilepsy patients implanted with the responsive neurostimulation (RNS) system requires the manual evaluation of hundreds of hours of intracranial recordings. The generation of these large amounts of data and the scarcity of experts’ time for evaluation, necessitates the development of automatic tools to detect intracranial electroencephalographic seizure patterns (iESPs) with expert-level accuracy. We developed an intelligent system for identifying the presence and onset time of iESPs in intracranial EEG (iEEG) recordings from the RNS device.

Sleep, oscillations, and epilepsy

Abstract

Sleep and wake are defined through physiological and behavioral criteria and can be typically separated into NREM sleep stages N1, N2, and N3, REM sleep and wake. Sleep and wake states are not homogenous in time. Their properties vary during the night and day cycle. Given that brain activity changes as a function of NREM, REM, and wake during the night and day cycle, are seizures more likely to occur during NREM, REM, or wake at a specific time? More ...

Integrated psychological care services within seizure settings: Key components and implementation factors among example services in four ILAE regions: A report by the ILAE Psychiatry Commission

Abstract

Mental health comorbidities are prevalent and problematic in patients with seizures but often suboptimally managed. To address common gaps in care, the Integrated Mental Health Care Pathways Task Force of the International League Against Epilepsy (ILAE) Psychiatry Commission was tasked with providing education and guidance on the integration of mental health management (e.g., screening, referral, treatment) into routine seizure care. This report aims to describe a variety of established services in this area, with a specific focus on psychological care ...

Temporal stability of intracranial EEG abnormality maps for localizing epileptogenic tissue

Abstract

Objective

Identifying abnormalities in interictal intracranial EEG, by comparing patient data to a normative map, has shown promise for the localization of epileptogenic tissue and prediction of outcome. The approach typically uses short interictal segments of around one minute. However, the temporal stability of findings has not been established.

Methods

Here, we generated a normative map of iEEG in non-pathological brain tissue from 249 patients. We computed regional band power abnormalities in a separate cohort of 39 patients for the duration of their ...

Sudden unexpected death in epilepsy during cenobamate clinical development

Abstract

Objective

We assessed mortality, sudden unexpected death in epilepsy (SUDEP), and standardized mortality ratio (SMR) among adults treated with cenobamate during the cenobamate clinical development program.

Methods

We retrospectively analyzed deaths among all adults with uncontrolled focal (focal to bilateral tonic-clonic [FBTC], focal impaired awareness, focal aware) or primary generalized tonic-clonic (PGTC) seizures who received ≥1 dose of adjunctive cenobamate in completed and ongoing phase 2 and 3 clinical studies. In patients with focal seizures from completed studies, median baseline seizure frequencies ranged ...

The role of the orexin system in the bidirectional relation between sleep and epilepsy: new chances for patients with epilepsy by the antagonism to orexin receptors?

Abstract

Epilepsy is a common neurological disorder, affecting patients of all ages, reducing the quality of life and associated with several comorbidities. Sleep impairment is a frequent condition in patients with epilepsy (PWE), and the relation between sleep and epilepsy has been considered bidirectional since one can significantly influence the other, and vice versa. The orexin system has been described more than 20 years ago and is implicated in several neuro-biological functions, other than in controlling the sleep-wake cycle. Considering the relation ...

kcna1a mutant zebrafish model episodic ataxia type 1 (EA1) with epilepsy and respond to first‐line therapy carbamazepine

Abstract

Objective

KCNA1 mutations are associated with a rare neurological movement disorder known as episodic ataxia type 1 (EA1), and epilepsy is a common comorbidity. Current medications only provide partial relief to ataxia and/or seizures, making new drugs needed. Here, we characterized zebrafish kcna1a
-/-
as a model of EA1 with epilepsy and compared the efficacy of the first-line therapy carbamazepine in kcna1a
-/-
zebrafish to Kcna1
-/-
rodents.

Methods

CRISPR/Cas9 mutagenesis was used to introduce a mutation in the sixth ...
