Two elderly patients presented with rapidly progressive dementia and their electroencephalograms showed periodic discharges. Creutzfeldt-Jakob disease was pathologically confirmed in one of the patients. Striking clinical features and characteristic electroencephalograms should prompt the clinical diagnosis in most patients.

Observation: A 61-year-old woman with a right hemisphere glioblastoma multiforme developed movements of the left hand that she claimed were not under her control, and she denied ownership of the affected limb. Simultaneous electroencephalograms documented continuous spikes in the right frontotemporal region. Intravenous diazepam therapy (2.5 mg) reversed both the abnormal movements and the spik...

A susceptible-infected-susceptible (SIS) cellular automaton model for collective neural interactions proposed recently is revisited. In this model, neurons are simple network nodes with different states: active or firing, and quiescent. The main thesis of this approach is that the electroencephalogram (EEG) could emerge as the fluctuations in the number of firing neurons. In this framework, EEG...

background: tramadol is a synthetic analgesic. seizures have been reported in patients receiving this drug. in this study we evaluated the correlation between tramadol consumption and seizure occurrence. methods: twenty-eight subjects with a history of tramadol consumption and seizure were studied. electroencephalograms (eeg) were performed in the first 24 hours and again one week later. subjec...

Ubiquitous robotics augments the capabilities of one or more robots by leveraging ubiquitous computational and/or sensorial resources. Augmentation complements and/or enhances the capabilities of one or more robots while such robots can simultaneously serve as intermediaries to ubiquitous services. Electroencephalograms (EEG) are Brain-Computer Interfaces that consist of a series of conductors ...

This paper presents the possibility of using Electroencephalograms (EEG) signals of an individual for quantitative interpretation of Cerebral Autoregulation (CA). EEG data was recorded during arm cuff inflation to induce dynamic changes in arterial blood pressure and then, Cerebral Blood Flow (CBF) was estimated from EEG using canonical hemodynamic response function (HRF). The assessment of CA ...

OBJECTIVE To investigate whether requests for standard paediatric electroencephalograms accord with guideline recommendations, subsequent changes in clinical management according to reported results, and extent to which the service meets waiting time targets. DESIGN Case series. SETTING Regional hospital, Hong Kong. PATIENTS All patients aged less than 18 years who underwent electroenceph...
