She presented with brief episodes of unconsciousness, tremulous movements of the upper limbs, and negative myoclonus, in addition to convulsive seizures. She also had prolonged episodes of dysarthria and oral motor dysfunction, a gradual decrease in speech output, impairment of finger movements, and deterioration in cognitive performance over several years. Her electroencephalography (EEG) recordings showed notable continuous sharp or sharp-slow discharges during sleep. Brain magnetic resonance images revealed no structural anomalies. Magnetoencephalographic analysis showed broadly distributed epileptic foci around the sylvian fissure, including a secondary source, explaining the specific prolonged neurological dysfunction. Antiepileptic drugs could control her seizures; however, they did not improve the other neurological symptoms or epileptiform discharge on EEG. Administration of low-dose prednisolone over a long period was effective for improving the neurological impairments of this patient.<\/jats:p>","DOI":"10.1177\/0883073810393307","type":"journal-article","created":{"date-parts":[[2011,2,16]],"date-time":"2011-02-16T14:55:02Z","timestamp":1297868102000},"page":"885-890","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Acquired Opercular Epilepsy With Oromotor Dysfunction: Magnetoencephalographic Analysis and Efficacy of Corticosteroid Therapy"],"prefix":"10.1177","volume":"26","author":[{"given":"Jun","family":"Tohyama","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Epilepsy Center, Nishi-Niigata Chuo National Hospital, Niigata, Japan,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriyuki","family":"Akasaka","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Epilepsy Center, Nishi-Niigata Chuo National Hospital, Niigata, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsukasa","family":"Ohashi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Epilepsy Center, Nishi-Niigata Chuo National Hospital, Niigata, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Epilepsy Center, Nishi-Niigata Chuo National Hospital, Niigata, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2011,2,15]]},"reference":[{"key":"atypb1","unstructured":"Tassinari CA, Michelucci R., Forti A., et al.
