Fever is sometimes associated with chill, myoclonus, delirium and convulsion. We previously reported EEG findings of febrile delirium, when we found that 18% of patients showed febrile myoclonus simultaneously with febrile delirium. The purpose of this study is to clarify the clinical features of febrile myoclonus and to investigate the ...

Identification of the epileptic focus is the most important requirement for a successful surgical outcome in intractable epilepsy. Patients with normal MRI on high-resolution imaging pose a significant challenge in this regard. We tried to identify the epileptic focus using interictal / ictal SPECT and ictal EEG patterns in 14 ...

PURPOSE: Dysembryoplastic neuroepithelial tumours (DNET) are an important cause of refractory partial epilepsies. They usually occur within dysplastic cortex and tend to affect the temporal lobes. The EEG of these patients is characterised by slowing and/or epileptiform abnormalities with a multifocal distribution. We studied the EEG features of epilepsy patients ...

Cholinergic deafferentation/recovery in rats mainly impinges on the fronto-parietal coupling of brain rhythms [D. P. Holschneider et al. (1999) Exp. Brain Res., 126, 270-280]. Is this reflected by the functional coupling of fronto-parietal cortical rhythms at an early stage of Alzheimer's disease (mild AD)? Resting electroencephalographic (EEG) rhythms were studied ...

OBJECTIVE: There is widespread consensus that the EEG is not useful for the detection of clinically relevant abnormalities in patients with psychosis. Given that the EEG records brain dysfunction, this study examines whether an abnormal EEG in first-episode psychosis patients is associated with poorer prognosis, compared with a normal EEG. ...

Whether the intrinsic epileptogenicity of hypothalamic hamartomas (HH) is responsible for the entire clinical spectrum of epileptic, neuropsychological and behavioural disorders associated with HH, remains an open issue, in as much as morphologically similar HH can be associated with dramatically different seizure types and cognitive outcomes. The aim of this ...

Combining electroencephalogram (EEG) and functional MRI (fMRI) allows localization of brain regions activated as a result of epileptic spikes. The statistical analysis of fMRI data usually includes a standard model of the hemodynamic response function (HRF) but it is not known how well this fits the actual HRF of epileptic ...

Non-convulsive status epilepticus (NCSE) is status epilepticus without obvious tonic-clonic activity. Patients with NCSE have altered mental state. An EEG is needed to confirm the diagnosis, but obtaining an EEG on every patient with altered mental state is not practical. To determine whether clinical features could be used to predict ...

Methylphenidate is commonly believed to lower seizure threshold. The safe use of methylphenidate has not been clarified in patients with attention-deficit hyperactivity disorder (ADHD) and concomitant active seizure or electroencephalographic (EEG) abnormalities. Patients with ADHD and active seizures (n = 57) and patients with ADHD and EEG abnormalities (n = ...
