症例は67歳女性で,意識障害を主訴に当院に入院した。心因性多飲により血清ナトリウムが115mEq/Lと著明に低下していた。脳波検査では全般性に5Hzの徐波が出現し,ジアゼパムの静注により徐波は著明に改善し,意識障害が回復したことから非痙攣性てんかん重積状態(NCSE)と判断した。レベチラセタム1,000mg/日の内服を追加し,低ナトリウム血症の補正を行った後に中止したが,再発はみられなかった。低ナトリウム血症を誘因としたNCSEの報告は少なく,早期の診断治療で良好な転帰を得たので報告する。
Abstract
We report the case of a 67-year-old woman with non-convulsive status epilepticus (NCSE) due to hyponatremia. She had a history of psychogenic polydipsia but not epilepsy. She was admitted to our hospital with dysbulia. On admission, she was confused and disoriented (Glasgow Coma Scale: 6, E1V1M4). Magnetic resonance imaging of the brain showed no abnormalities. Laboratory test showed hyponatremia (Na+ level: 115 mEq/L). The electroencephalography (EEG) showed a generalized slow wave of 5 Hz during recording. The slow wave was promptly suppressed by diazepam and levetiracetam administered intravenously and orally, respectively. After the hyponatremia was treated the seizures stopped and did not reoccur, even after cessation of the anticonvulsant drugs. The patient was discharged with no neurological deficits. Few reports have described this condition. Here we discuss the diagnosis and treatment of NCSE due to hyponatremia.
