초점성 무긴장성 발작으로 의심되는 적하 발작 1례

A Case of Suspicious Focal Atonic Seizure Characterized by Drop Attack

저자들은 정상적인 발달을 보이다가 12세경부터 하루에 수차례 걸친 양 하지 근력 저하로 인한 낙상으로 내원한 환아의 각성 뇌파에서 발작간 간질파를 관찰함으로써 비록 비디오-뇌파-근전도 모니터 및 침습적 뇌파 소견을 얻지 못하였으나 임상적으로 환아의 반복적 낙상의 원인이 하지에 국한된 초점성 무긴장성 간질 발작으로 사료되어 문헌고찰과 함께 보고 하고자 한다.

Atonic seizures exhibits loss of postural tone, resulting in head drops or falling. When this event is extremely brief, It has been known as a drop attack. Atonic seizure are firmly placed under the category of generalized seizures. However, a various phenomena satisfying the above description has been recognized in patients with partial seizures. A 13-year-old girl had brief episodes of drop attacks. She complained of weakness of both legs in the absence of consciousness loss. These episodes occurred at a frequency of 4 or 5 time per day for 1 year. Her developmental and physical examinations were normal. Also, the brain MRI was normal. However, her Interictal EEG showed the repetitive spike and wave complexes on Cz electrode. She was controlled completedly by antiepileptic drungs. We report a patient who suffered from focal atonic seizures characterized by drop attack.
