Limb shaking (LS) is often confused with focal motor seizures. Distinguishing between both is crucial, because LS may represent an indicator of severe carotid occlusive disease and patients are at high risk of stroke. We report the case of a patient with occlusive carotid stenosis without definite stroke who develops partial motor status epilepticus (SE). Clinical, neuroimaging and electroencep...
It has been known for decades that suppression of spontaneous scalp electroencephalographic activity occurs during ischaemia. Trend analysis for such suppression was found useful for intraoperative monitoring during carotid endarterectomy, or as a screening tool to detect delayed cerebral ischaemia after aneurismal subarachnoid haemorrhage. Nevertheless, pathogenesis of such suppression of acti...
Multidomain comfort theories have been demonstrated to interpret human thermal in buildings by employing human-centered physiological measurements coupled with environmental sensing techniques. Thermal has correlated brain activity through electroencephalographic (EEG) measurements. However, the application of low-cost wearable EEG sensors for measuring not thoroughly investigated. Wearable dev...
Burst suppression patterns in the electroencephalogram are a reliable marker of recent severe brain insult. Here we analyze statistical properties of bursts occurring in 20 electroencephalographic recordings acquired from hypothermic asphyxic newborns in the hours immediately following birth. We show that the distributions of burst area and duration in these acute data predict later clinical ou...
OBJECTIVE In patients with medically intractable partial epilepsy of mesiotemporal origin, video electroencephalographic monitoring with foramen ovale electrodes is necessary to plan neurosurgical interventions. Imaging of these electrodes after implantation hitherto required conventional radiography, magnetic resonance imaging, or computed tomography of the skull. These methods are expensive. ...
BACKGROUND Nonvasculitic autoimmune inflammatory meningoencephalitis and Creutzfeldt-Jakob disease can present as rapidly progressive encephalopathies with similar clinical features. Slowing of background rhythm is an electroencephalographic characteristic shown by both, but persistent periodic sharp waves are more specific for Creutzfeldt-Jakob disease and have not been reported in nonvasculit...
We evaluated the effects of treatment with the inner ester derivative of the monosialoganglioside GM1 on cortical electroencephalographic activity and hippocampal CA1 morphology after transitory, near-complete cerebral ischemia in rats. Ischemia was induced by the four-vessel occlusion method, and we studied only the 58 rats that showed flattening of the cortical electroencephalogram for the en...
