Focal-onset myoclonic seizures and secondary bilateral synchrony.
نویسندگان
چکیده
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 myoclonic seizures can be focal in origin despite bilaterally synchronized epileptiform discharges on scalp EEG.

Motor correlates of models of secondary bilateral synchrony and multiple epileptic foci
Bilateral synchronous epileptiform discharges registered in patients with partial epilepsies may be generated by different pathophysiological mechanisms. Differentiation between underlying mechanisms is often crucial for correct diagnosis and adequate treatment in clinical epileptology. The aim of this study was to model in rats two possible mechanisms--secondary bilateral sychrony and interact...

[TOP] Responsive neurostimulation (RNS) may be considered medically necessary for patients with partial epilepsy who meet ALL of the following criteria: Are 18 years or older. Have a diagnosis of partial-onset seizures with 1 or 2 well-localized seizure foci identified. Have an average of 3 or more disabling seizures (e.g., motor partial seizures, complex partial seizures, or secondary ge...
متن کاملEEG-fMRI as an useful tool to detect epileptic foci associated with secondary bilateral synchrony
INTRODUCTION Tailoring the epileptic cortex is the key issue in the pre-surgical work-up of patients with pharmacoresistant focal epilepsy. Not always, however, the conventional MRI and the scalp EEG are able to provide the information needed to address this issue since the imaging may be normal (criptogenetic epilepsy) and the EEG, even ictal, poorly localizing. PATIENT AND METHODS We presen...
متن کاملOperational classification of seizure types by the International League Against Epilepsy: Position Paper of the ILAE Commission for Classification and Terminology.
The International League Against Epilepsy (ILAE) presents a revised operational classification of seizure types. The purpose of such a revision is to recognize that some seizure types can have either a focal or generalized onset, to allow classification when the onset is unobserved, to include some missing seizure types, and to adopt more transparent names. Because current knowledge is insuffic...

Most types of epilepsy are characterized by more than one type of seizure. Patients with focal (or partial) epilepsy may ha...
