Oscillatory and coherent EEG activity is increasingly recognized as a fundamental hallmark of cortical integrative functions. We aimed to study deviations from the norm of different resting EEG parameters in Parkinson's disease (PD) patients. We compared spectral parameters of the resting EEG of PD patients (n=24, median age 67 years) ...

The regulation of brain activation, as assessed with the EEG, is a state modulated trait. A decline to lowered EEG-vigilance states has been found to be associated with emotional instability in older studies, but has not been systematically studied in patients with borderline personality disorder (BPD). Twenty unmedicated BPD patients ...

BACKGROUND: Alpha-[11C]methyl-L-tryptophan (alpha-MTrp) positron emission tomography (PET) is a promising tool in the localization of the epileptogenic area in selected group of focal epilepsy patients. Electrophysiological evidence suggests the involvement of the neocortex in periventricular nodular heterotopia (PVNH). PURPOSE: To determine whether alpha-MTrp PET can detect neocortical changes in patients ...

We appreciate the interest of Dr Tang in our article. Certainly, our previous results should be taken with caution due to the small database size. Nevertheless, it must be noted that this limitation was clearly recognized in our article. Furthermore, our hypothesis is completely justified from the current state of ...

To define the clinical significance of EEG "cyclic alternating pattern" (ECAP). ECAP is the periodic presence of a high-voltage slow waves alternating with low voltage irregular faster activity. This term was first described in comatose patients in 1944. It has been less recognized and may be underreported since then. The ...

Nonconvulsive status epilepticus is defined as a mental status change from baseline of at least a 30-min duration associated with constant or near-continuous ictal discharges on an electroencephalogram (EEG). Nonconvulsive status epilepticus is an often-overlooked diagnosis as a cause of acute confusional state. There are few case reports in dialysis ...

The antipsychotic agent clozapine (ClozarilE) is reserved for the treatment of refractory psychosis. Clozapine has allowed many schizophrenic patients to lead more independent and productive lives, but its use is restricted by side effects. Clozapine has been shown to lower seizure threshold and produce significant EEG changes. Although not a ...

BACKGROUND: The histology of melanocytic nevi removed from older patients often differs from that of nevi from younger adults. According to the literature, the most common nevus in older individuals is the intradermal nevus, and purely junctional nevi are rare and should alert the pathologist to a possible melanoma precursor. ...

PURPOSE: The diagnosis of frontal lobe epilepsy may be compounded by poor electroclinical localization, due to distributed or rapidly propagating epileptiform activity. This study aimed at developing optimal procedures for localizing interictal epileptiform discharges (IEDs) of patients with localization related epilepsy in the frontal lobe. To this end the localization ...

Intermittent photic stimulation (IPS) is an activating procedure meant to elicit or accentuate epileptiform discharges during an EEG. There is insufficient clinical data to advocate IPS in the routine EEGs of all adult patients. We therefore sought to address the clinical significance of routine IPS in the adult population. We ...

Although a wide spectrum of reversible periictal magnetic resonance imaging (MRI) abnormalities (RPMA) are being increasingly identified, the clinicians are often in a dilemma about their localization significance. This prompted us to analyze the clinical, MRI, electroencephalographic (EEG) and follow-up data of 12 patients with RPMA seen in a tertiary ...

Episodes of syncope or breath-holding spells are often misdiagnosed as epileptic events. The purpose of this study was to assess the usefulness of an electroencephalogram (EEG) with ocular compression to distinguish breath-holding spells and syncope from epileptic seizures. A retrospective analysis was performed on the EEG records of all children ...

Initially described as a rare MCA/MR syndrome occurring only in boys, due to a recessive mutation on the X chromosome [Opitz and Kaveggia, 1974], the FG syndrome (FGS) now emerges as a more common disorder also occurring in girls. Based on over 50 reported cases, FGS is associated with developmental ...

OBJECTIVE: The EEG provides an objective staging of hepatic encephalopathy (HE), but its interpretation may be biased by inter-observer variability. This study aims at comparing an entirely automatic EEG classification of HE based on an artificial neural network-expert system procedure (ANNES) with visual and spectral analysis based EEG classifications. METHODS: ...

This paper discusses the 50-Hz artifact observed during EEG recording of three patients, using Mindset24 equipment in a biomedical laboratory along with other instruments. The artifact at 50 Hz is created due to electromagnetic (EM) radiation from the environment. Perhaps, the nullification of 50 Hz artifact occurs by the three ...

Stimulus-induced rhythmic EEG discharges (SIRDs) is a recently reported phenomenon in critically ill patients and little is known about their evolution. We found SIRDs in three patients with encephalopathy and followed them with serial EEGs. SIRDs appeared between 4 and 13 days after the onset of illness and persisted for ...
