A patient with rapidly progressive cognitive decline over an approximately four month period was suspected to have sporadic Creutzfeldt-Jakob disease. Features thought to support this diagnosis included psychiatric symptoms (anxiety and depression), visual hallucinations and a visual field defect. However, the finding of papilloedema broadened the differential diagnosis. Although standard brain...

Electroencephalography (EEG) is a valuable diagnostic test to identify functional disturbances in brain activity. The purpose of this study was to assess the validity of EEG as a diagnostic indicator of intracranial diseases in horses. The validity of EEG was estimated by comparing clinical, clinicopathologic, and histopathologic findings to EEG findings in 20 horses examined for seizures. coll...

Behavioral studies of visual recognition memory indicate that old/new decisions reflect both the similarity of the probe to the studied items (probe-item similarity) and the similarities among the studied items themselves (list homogeneity). Recording intracranial electroencephalography from 1,155 electrodes across 15 patients, we examined the oscillatory correlates of probe-item similarity and...

Introduction: To obtain a baseline for clinical application of Electroencephalography in children and to evaluate the Electroencephalography findings in children with various acute and chronic CNS disorders and non epileptic events.Methods: electroencephalography Electroencephalography records of 250 patients were studied in neurophysiology departments of Queen Rania AL-Abdullah Hospital for ch...

The brain regions subserving the processing of emotional prosody have been investigated using functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) but few studies investigated direct electrical neuronal activity using intracranial recordings in humans. Previous studies have shown the involvement of the amygdala and the orbito-frontal cortex (OFC) in the processing of em...

Several procedures have been proposed to be capable of predicting the occurrence of epileptic seizures. Up to now, all proposed algorithms are far from being sufficient for a clinical application. This is, however, often not obvious when results of seizure prediction performance are reported. Here, we discuss impacts of long prediction horizons with respect to clinical needs and the strain on p...
