We report that long-term selective immunoglobulin G immunoadsorption by protein A (PAI) improved seizure frequency and neuropsychological deficits in a 16-year-old patient with severe treatment-resistant Rasmussen's encephalitis (RE). Clinical improvement correlated with reduction of antiglutamate receptor 3 antibodies. The efficacy of PAI in our patient supports the autoimmune hypothesis of RE and suggests its application to avoid, or at least delay, functional hemispherectomy in selected cases.
A longitudinal linguistic analysis of aphasic disorder in a 15-year-old boy affected by Landau-Kleffner syndrome followed since the age of 6 is reported. The phonological, morphosyntactic and lexical levels of verbal deficits have been evaluated by means of collected samples of spontaneous language and a battery of linguistic tests. The clinical course has fluctuated with improvement and worsening of aphasia and epilepsy; at the end of the follow-up the boy was seizure-free and a medium-degree disturbance in language production and comprehension was present. The results of the linguistic evaluation suggest that the aphasic disturbance was related to a deficiency in phonological decoding which leads to phonological, morphosyntactic and lexical disturbances. A temporal relationship between the electroclinical picture and the aphasia has been observed: the persistent improvement in linguistic performances took place only after the disappearance of the seizures and of the EEG epileptic anomalies during sleep.
A retrospective study in which 709 patients, 522 with RIND and 187 with TIA, were compared in respect of common risk factors (RFs) for acute cerebrovascular disease. The two forms of the disease differed significantly in respect of smoking, hematocrit, hypercholesteremia, hypertriglyceridemia and hyperuricacidemia. Although these RFs do not seem to be determinants of or discriminants between the two forms of acute cerebrovascular disease, it is nonetheless highly probable that, together with all the other RFs, they have a facilitatory role.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
