To compare surgical outcome in mesial temporal lobe epilepsy (MTLE) patients with unilateral hippocampal sclerosis (MTLE-HS) who had or did not have preoperative video-electroencephalographic monitoring (VEEG).
A prospective study was undertaken with 166 consecutive pharmacoresistant unilateral MTLE-HS patients.
Our purpose was to determine the correlation between scalp electroencephalography (EEG) and intracerebral EEG (iEEG) seizure-onset patterns in patients with focal lesional epilepsy to determine whether scalp seizure-onset patterns can be specific to intracerebral seizure-onset patterns and to lesion type.
To characterize the evolution of behavioral and electrographic seizures in an experimental electrical stimulation-based model of status epilepticus (SE) in C57Bl/6 mice, and to relate SE to various outcomes, including death and epileptogenesis.
SE was induced by continuous hippocampal stimulation and was evaluated by review of electroencephalographic recordings, spectral display, and behavior.
Over the past decade there has been an increasing interest in using cannabinoids to treat a range of epilepsy syndromes following reports of some remarkable responses in individual patients. The situation is complicated by the fact that these agents do not appear to work via their attachment to endogenous cannabinoid receptors.
Drug shortages are occurring at an increasing rate. From May to October 2016, there was a shortage of a level I critical antiepileptic drug, clobazam. We aimed to study the impact of this shortage on patients with epilepsy.
Adult patients from Calgary’s Comprehensive Epilepsy Program who were taking clobazam were approached to participate in the study.
Antiepileptic drugs (AEDs) are routinely withdrawn during long-term video–electroencephalography (EEG) monitoring (LTM), to record sufficient number of seizures. The efficacy of rapid and slow AED taper has never been compared in a randomized control trial (RCT), which was the objective of this study.
We conducted a prospective cohort study, examining long-term adherence with psychiatric treatment among patients with psychogenic nonepileptic seizures (PNES). Subjects diagnosed with documented PNES were scheduled for 4 psychiatric visits. Survival analysis was performed, and covariates were assessed for association with time to nonadherence using Cox proportional hazard regression analysis.
Identification of patient-specific epileptogenic networks is critical to designing successful treatment strategies. Multiple noninvasive methods have been used to characterize epileptogenic networks. However, these methods lack the spatiotemporal resolution to allow precise localization of epileptiform activity. We used intracranial recordings, at much higher spatiotemporal resolution, across a cohort of patients with mesial temporal lobe epilepsy (MTLE) to delineate features common to their epileptogenic networks.
