Improving the inter-rater agreement of hypsarrhythmia using a simplified EEG grading scale for children with infantile spasms
BACKGROUND There is poor inter-rater agreement in determining the presence or absence of hypsarrhythmia among patients with infantile spasms. Yet, remission of hypsarrhythmia has been used as a clinical and research outcome measure. Two important features of hypsarrhythmia are the burden of epileptiform discharges and the amplitudes of background slow waves. We hypothesized that an electroencep...
متن کاملAsymmetric hypsarrhythmia: clinical electroencephalographic and radiological findings.
Twenty-six children (16 boys and 10 girls) with hypsarrhythmia and infantile spasms (IS) were studied at the University of Michigan EEG Laboratory in a 4-year period. Six (2 boys, 4 girls), had asymmetric hypsarrhythmia with a preponderance of both slowing and epileptiform activity over one hemisphere. All 6 had the symptomatic form of IS, 4 with dysplastic conditions, 1 with porencephaly from ...

tuberous sclerosis) (11–13). Therefore, most recently the treatment of WS with valproate has been overtaken and overlooked (14, 15). Overall, the treatment strategies in WS [either the first-line treatments (e.g., ACTH and vigabatrin) or the more classical nongolden treatments (e.g., valproate or other newer anticonvulsants)] are based on the assumption that an early initiation of therapy coupl...
متن کاملEpileptic spasms in clusters without hypsarrhythmia in infancy.
Spasms are defined as epileptic seizures characterized by brief axial contraction, in flexion, extension or mixed, symmetric or asymmetric, lasting from a fraction of a second to 1-2s, and are associated with a slow-wave transient or sharp and slow-wave complex, followed or not by voltage attenuation. Epileptic spasms usually appear in clusters and are age-dependent. This type of epileptic spas...
