Interictal 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 کاملInterictal epileptiform discharge effects on neuropsychological assessment and epilepsy surgical planning.
Both animal research and human research suggest that interictal epileptiform discharges (IEDs) may affect cognition, although the significance of such findings remains controversial. We review a wide range of literature with bearing on this topic and present relevant epilepsy surgery cases, which suggest that the effects of IEDs may be substantial and informative for surgical planning. In the f...
متن کاملInterrater Agreement and Combining Ratings
Some behaviors such as smiles require human raters for their measurement. A model of the rating process is explored that assumes that the probability distribution of overt rating responses depends on which of several underlying or latent responses occurred. The ideal of theoretically identical raters is considered and also departures from such identity. Methods for parameter estimation and asse...
متن کاملDetection 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 کاملThe BOLD response to interictal epileptiform discharges.
We studied single-event and average BOLD responses to EEG interictal epileptic discharges (IEDs) in four patients with focal epilepsy, using continuous EEG-fMRI during 80-min sessions. The detection of activated areas was performed by comparing the BOLD signal at each voxel to a model of the expected signal. Since little is known about the BOLD response to IEDs, we modeled it with the response ...
