Advances in sleep-related hypermotor epilepsy / 浙江大学学报·医学版

ABSTRACT

Sleep-related hypermotor epilepsy (SHE), formerly known as nocturnal frontal epilepsy, is characterized by asymmetrical tonic or complex hypermotor seizures during sleep, with transient, frequent and clustering attack. The accurate incidence is not known but somehow low, which is estimated about 1.8/100 000. The differential diagnosis between SHE and parasomnias may be challenging due to possible similarities between the two sleep-related manifestations. In a majority of patients, the etiology is unknown. Identified etiologies are heterogeneous and structural abnormalities,which are involved in the severity and prognosis of SHE. In terms of treatment, it mainly includes pharmacological therapy and surgery. Carbamazepine seems to be the drug of choice in SHE patients, and epilepsy surgery provides excellent results in selected drug-resistant SHE cases. This review will focus on diagnosis, pathogenesis, treatment and prognosis of SHE, aiming to promote its early diagnosis and appropriate treatment.
