BACKGROUND: Prior studies have shown that the electroencephalogram (EEG) is of low diagnostic yield in the evaluation of syncope but have not looked at the yield according to referring physician specialty. The goals of this study were to determine if the yield of the EEG is higher when ordered by ...

Febrile status epilepticus is an important neurological emergency and a risk factor for later development of epilepsy. There are guidelines recommending against the use of EEG in the evaluation of simple febrile seizures but the role in febrile status epilepticus is not well established. This article reviews the literature on ...

BACKGROUND: In assessing neurologic prognosis after cardiac arrest (CA), electroencephalogram (EEG) reactivity has not been specifically included with EEG classifications. Most studies have divided recordings into benign and malignant; however, some patterns within these groups may have greater prognostic significance than such broad classifications. We sought to explore reactivity, with ...

A female infant suffered from epilepsy since the neonatal period, which evolved into West syndrome at the age of 2 months. Spasms in series and hypsarrhythmia disappeared after treatment with high-dose phenobarbital; however, single spasms persisted with right-sided predominance, and polyspike activity in the left parieto-temporal areas preceded or coincided ...

A 87-year-old woman was admitted with a rapidly progressive confusion, disorientation and myoclonus, all suggestive of sporadic Creutzfeldt-Jakob disease (sCJD). This diagnosis was initially strongly supported by the EEG, which showed slow background activity and triphasic waves, combined with the finding of an increased level of 14-3-3 protein in the ...

The visual analysis of EEG has shown useful in helping the diagnosis of Alzheimer disease (AD) when the diagnosis remains uncertain, being used in some clinical protocols. However, such analysis is subject to the inherent equipment imprecision, patient movement, electrical records, and physician interpretation of the visual analysis variation. The ...

A passive oddball experiment was used in which stimuli were emotional exclamations differing in their affective tone. In both electroencephalography (EEG) and magnetoencephalography (MEG), deviants elicited an N300 component, sometimes accompanied by a slow wave. Both components had a symmetrical distribution, but the former was more posterior than the latter. ...

Seven patients with idiopathic generalized epilepsies were investigated using MEG and EEG. Spike-wave series were seen in all patients, single spikes in six. For both, source analysis showed most often involvement of frontal, perinsular and subcortical/thalamic areas. In all patients, a unilateral frontal accentuation of activity could be observed. Patients ...

PURPOSE: Simultaneous electroencephalogram and functional magnetic resonance imaging (EEG-fMRI) in patients with focal epilepsy and unilateral spikes often shows positive blood oxygenation level-dependent (BOLD) responses (activations), not only ipsilateral but also contralateral to the spikes. We aimed to investigate whether minimal EEG changes could underlie these contralateral BOLD responses by ...

Non-convulsive seizures and status epilepticus are common in brain-injured patients in intensive care units. Continuous electroencephalography (cEEG) monitoring is the most sensitive means of their detection. In centres where cEEG is unavailable, routine EEG is often utilized for diagnosis although its sensitivity is lower. To establish the rate of electrographic ...

OBJECTIVE: High power of pre-stimulus cortical alpha rhythms (about 8-12 Hz) underlies conscious perception in normal subjects. Here we tested the hypothesis that these rhythms are abnormal in persistent vegetative state (PVS) patients, who are awake but not aware of self and environment. METHODS: Clinical and resting-state, eyes-closed electroencephalographic (EEG) ...

OBJECTIVE: To test the accuracy of EEG source imaging in epilepsy patients with large cerebral lesions. It is hypothesized that lesions are most likely to change conductivity properties and to significantly impair the accuracy of electromagnetic source imaging (ESI) based on the EEG. This has, however, not been tested in ...

In this paper, we propose a new method for diagnosing Alzheimer's disease (AD) on the basis of electroencephalograms (EEG). The method, which is termed "Power Variance Function (PVF) method", indicates the variance of the power at each frequency. By using the proposed method, the power of EEG at each frequency ...

In this study we investigated the existence and the nature of rhythmic changes in EEG associated with ventilatory oscillations in heart failure (HF) patients with periodic breathing (PB). Since nonlinear mechanisms are thought to be involved in the generation of EEG, we hypothesized that a mathematical approach based on nonlinear ...

EEG-based discrimination between different motor imagery states has been subject of a number of studies in healthy subjects. We investigated the EEG of 15 patients with complete spinal cord injury during imagined right hand, left hand, and feet movements. In detail we studied pair-wise discrimination functions between the 3 types ...

Delirious behavior is one of the main clinical features in patients with clinically mild encephalitis/encephalopathy with a reversible splenial lesion. On the other hand, it has been reported that more than 10% of patients with influenza in Japan develop delirious behavior. Magnetic resonance imaging (MRI) studies in patients with influenza-associated ...

Several reports in the literature have described the value of regional cerebral oximetry (rSO(2)) as a neuromonitoring device during carotid endarterectomy (CEA). The use of rSO(2) is enticing because it is simpler and less expensive than other neuromonitoring modalities. This study was performed to compare the efficacy of rSO(2) with ...

A total of 77 patients with panic attacks (PA) with and without agoraphobic disorders were studied, along with 28 healthy subjects. Use of clinical-neurological investigation methods was supplemented by psychological methods, EEG recordings, and auditory event-linked evoked potentials (EP). Patients with PA with agoraphobic disorders were found to be characterized ...

We examined the usefulness of video versus EEG in isolation for the differentiation of epileptic seizures (ES) from psychogenic nonepileptic events (PNEE). Video-EEG recordings of 43 events in 43 patients (27 with ES and 16 with PNEE) were analyzed by experienced clinical epileptologists/electroencephalographers blinded to the patients' clinical histories. Both ...
