Detection of Interictal Epileptiform Discharges in Eeg
The diagnosis of epilepsy heavily depends on the detection of epileptiform discharges in interictal EEG, the EEG in between two seizures. By visual analysis a physician wants to detect these epileptiform discharges (spikes). Due to the wide variety of morphologies of epileptiform discharges, and their similarity to waves that are part of normal EEG or to artifacts, this detection is far from st...
متن کاملInterictal Epileptiform Discharges
EEG remains the primary technique in the diagnosis, characterization, and localization of partial seizures. This review examines the significance and character of interictal epileptiform abnormailites, periodic lateralized epileptiform discharges, and ictal patterns in patients with partial epilepsy. Interictal epileptiform discharges are common and assist in the diagnosis and localization of p...
متن کاملReproducible localization of interictal epileptiform discharges using EEG-triggered fMRI.
We report preliminary experiences using fMRI triggered by EEG to localize the site of interictal epileptiform activity. EEG was recorded in the scanner and monitored on-line; the recording quality was good enough to allow the clear identification of spikes in the EEG. Snap-shot EPI was performed 2-4 s after an epileptiform discharge ('spike') or after at least 10 s of background activity ('rest...
متن کاملfNIRS-EEG study of focal interictal epileptiform discharges.
Functional near-infrared spectroscopy (fNIRS) acquired with electroencephalography (EEG) is a relatively new non-invasive neuroimaging technique with potential for long term monitoring of the epileptic brain. Simultaneous EEG-fNIRS recording allows the spatio-temporal reconstruction of the hemodynamic response in terms of the concentration changes in oxy-hemoglobin (HbO) and deoxy-hemoglobin (H...
متن کاملEffect of chronic vagal nerve stimulation on interictal epileptiform discharges
We evaluated the effect of vagus nerve stimulation (VNS) on interictal epileptiform discharges (IEDs) in 32 epileptic patients (18 females; 14 males) with an average age of 42.2+/-11.4 years, all of whom had been suffering from epilepsy for an average of 29.2+/-14.5 years. All of the patients had received VNS for 5 years. The first EEG was performed prior to the initiation of stimulation; the s...
