Focal fast rhythmic epileptiform discharges on scalp EEG in a patient with cortical dysplasia
نویسندگان
چکیده
A distinctive scalp electroencephalographic (EEG) pattern of focal fast rhythmic epileptiform discharges (FREDs) in a 23-year-old man with symptomatic localization related epilepsy is presented. Magnetic resonance imaging (MRI) of the brain revealed cortical dysplasia over the right temporal region where the peculiar EEG abnormality was detected. We suggest that this characteristic EEG pattern may be predictive of focal cortical dysplasia (FCD). A brief review of the rhythmic EEG abnormalities in FCDs is also presented.

Focal-onset myoclonic seizures and secondary bilateral synchrony.
We present a child with myoclonic seizures, epileptic spasms and generalized epileptiform discharges on scalp EEG. Magnetoencephalography and coherence-phase analysis for scalp EEG suggested focal onset in the left hemisphere. Intracranial video EEG confirmed seizure onset in the left frontal lobe with ictal high-frequency oscillations. Left frontal lobectomy suppressed his seizures. Subsets of...
متن کاملEEG-triggered functional MRI of interictal epileptiform activity in patients with partial seizures.
EEG-triggered functional MRI (fMRI) offers the potential to localize the generators of scalp EEG events, such as interictal epileptiform discharges, using a biological measurement as opposed to relying solely on modelling techniques. Although recent studies have demonstrated these possibilities in a small number of patients, wider application has been limited by concerns about patient safety, s...
متن کاملFocal Epileptogenic Lesions in Adult Patients with Epilepsy and Generalized Epileptiform Discharges
BACKGROUND AND PURPOSE There are reports of successful resective epilepsy surgery for pediatric patients with epilepsy and generalized epileptiform discharges when they had focal epileptogenic lesions identified by MRI. However, there is limited information regarding adult patients with epilepsy who have both generalized epileptiform discharges and focal epileptogenic lesions. METHODS To inve...
متن کاملChronic PLEDs with transitional rhythmic discharges (PLEDs-plus) in remote stroke.
Background. Periodic lateralized epileptiform discharges (PLEDs) are a rare phenomenon in electroencephalography, occurring in acute structural brain lesions. In general, PLEDs appear transiently in acute lesions, but a few reports have described persistent PLEDs in chronic lesions. Case report. An 86-year-old female was admitted, in 1999, with a left MCA stroke associated with right hand focal...
متن کاملSimilarity of lateralized rhythmic delta activity to periodic lateralized epileptiform discharges in critically ill patients.
IMPORTANCE The increasing use of continuous electroencephalography (EEG) monitoring in the intensive care unit has led to recognition of new EEG patterns that are of unclear or unknown significance. OBJECTIVE To describe an EEG pattern, lateralized rhythmic delta activity (LRDA), encountered in critically ill subjects and determine its clinical significance in this setting. DESIGN, SETTING, A...
