PURPOSE The aim of our study was to test the efficacy of the VARIA system (video, accelerometry, and radar-induced activity recording) and validation of accelerometry-based detection algorithms for nocturnal tonic-clonic and clonic seizures developed by our team. METHODS We present the results of two patients with tonic-clonic and clonic seizures, measured for about one month in a home enviro...

BACKGROUND Poor agreement between observers on whether an unusual event is a seizure drives the need for a specific diagnostic tool provided by video-electroencephalography (video-EEG) in human pediatric epileptology. OBJECTIVE That successful classification of events would be positively associated with increasing EEG recording length and higher event frequency reported before video-EEG evalu...

Background: Seizures affect 1.5 - 1.3/1000 live births at term and are associated with worse neurodevelopmental outcomes. 80-90% of neonatal seizures subclinical. Amplitude integrated electroencephalography raw EEG video images (video aEEG/EEG) is an alternative for seizure assessment the bedside.

An evaluation of the clinical yield of inpatient long-term video-EEG (vEEG) in a new epilepsy monitoring unit (EMU) was undertaken, with findings compared to the centre's prior method of bedside vEEG recording in a standard neurology ward, as reported in 2004. A retrospective analysis of neurophysiology reports for all adults who underwent elective vEEG monitoring in the EMU at Cork University ...

Several clinical signs have been described for lateralization and localization of seizure focus in complex partial seizures; however, the specificity of each of these has been widely debated upon. The present study was done to evaluate 'dystonic unilateral limb posturing' and 'versive head movements' for lateralization and localization of epileptic foci in patients with intractable partial comp...

The electroencephalogram (EEG) is a classic noninvasive method for measuring a person's brain waves and is used in a large number of fields: from epilepsy and sleep disorder diagnosis to brain-computer interfaces (BCIs). Electrodes are placed on the scalp to detect the microvolt-sized signals that result from synchronized neuronal activity within the brain. Current long-term EEG monitoring is g...

A reliable method for the estimation of seizure frequency and severity is indispensable in assessing the efficacy of drug treatment in epilepsies. These quantities are usually deduced from subjective patient reports, which may cause considerable problems due to insufficient or false descriptions of seizures and their frequency. We present data from two difficult-to-treat patients with intractab...

Juvenile myoclonic epilepsy (JME) is a frequent idiopathic generalised epilepsy syndrome with typical clinical and EEG features that can usually be controlled by valproate monotherapy. JME may be underdiagnosed or misdiagnosed; in the latter case, it may be mistaken for partial epilepsy. The incorrect diagnosis of JME is likely to result in inappropriate therapy, which may, in turn, worsen the ...

Vocalizations may occur in focal epileptic seizures, which typically arise from frontal and temporal regions. They are commonly associated with other motor phenomena such as automatisms, tonic posturing, or head version. We report on a patient whose seizures were documented by video-EEG monitoring, but in whom the observable ictal semiology consisted solely of a brief, monotonous vocalization. ...
