Influence of Sleep and Sleep Deprivation on Ictal and Interictal Epileptiform Activity
Sleep is probably one of the most important physiological factors implicated both in epileptic seizures and interictal epileptiform discharges. The neurophysiology concerning the relationship between sleep and epilepsy is well described in the literature; however, the pathological events that culminate in the seizures are poorly explored. The present paper intends to make a rigorous approach to...
متن کاملInterictal epileptiform discharges do not change before seizures during sleep.
PURPOSE Whether interictal epileptiform discharges (IEDs) increase, decrease, or are unchanged before epileptic seizures has implications for the pathophysiology of epilepsy. Prior studies relating IEDs and seizures have not demonstrated a change in IEDs before seizures. However, they have not controlled for changes in the depth of sleep. Our objective was to test the hypothesis that IEDs are r...
متن کاملInterictal epileptiform discharges and phasic phenomena of REM sleep.
The objective of this study was to assess the effect of phasic rapid eye movement (REM) sleep events on interictal epileptiform discharges (IEDs). Twelve patients with focal epilepsy and IEDs during REM sleep were examined by video-EEG monitoring. The number of IEDs was calculated in different REM sleep episodes according to the rate of rapid eye movements. A negative correlation was identified...
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 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 ...
