Ictal paresis associated to PLEDS in two children: A video-EEG study
2008
Summary Ictal paresis (IP) is a rare negative motor phenomenon presenting challenging differential diagnostic problems with transient ischemic attacks, post-ictal paralysis, migraine and psychogenic paralysis. Video-EEG undoubtedly represents the essential mean for a proper diagnosis. Periodic lateralised epileptiform discharges (PLEDs) are a distinctive EEG pattern, consisting of periodic spike or sharp wave discharges, often associated with seizures. It is under debate if PLEDs should be considered only a peri-ictal or also an ictal EEG pattern. We describe two children with severe focal epilepsies, who presented IP recorded during video-EEG monitoring, associated to PLEDs. Clinical observation along with interictal and ictal scalp-EEG findings, suggested a fronto-temporal seizure onset in the first, and a temporo-insular onset in the second. We confirm that PLEDs may be an ictal pattern associated with negative motor phenomena.
