Abstract：
Objective: Sleep-related hypermotor epilepsy (SHE) is a sleep-related focal epilepsy which is often misdiagnosed. Despite active pharmacological therapy in the management of this disorder, satisfactory seizure control still cannot be achieved. Therefore, the aim of the present study was to identify this disorder among people who were seeking medical advice at Cairo University Epilepsy Unit (CUEU), characterizing its clinical, electroencephalographic and imaging features besides identifying possible indicators of inadequate seizure control on drug-therapy. Patients and methods: This study was carried out on 26 patients with SHE who were subjected to detailed history taking and examination in addition to home video recording, video electroencephalographic (EEG) monitoring and brain imaging. Ictal semiology and EEGs were reviewed and analyzed by experienced neurologists. Results: SHE is an uncommon sleep-related focal epilepsy. In our series, median age of the patients was 18.5 years. It is characterized by being sporadic, with often frontal lobe seizure onset (14/26, 53.8%) and with occasional occurrence in wakefulness. Adolescence age at disease onset (11 years, 6-15), duration less than 1 min, clustering, lack of auras and often uninformative brain imaging (22/25, 88%) are all documented features. Moreover, it has a relatively poor outcome on pharmacological therapy (16/26, 61.5%). Longer disease duration (>4.5 years) was a significant feature of the patients exhibiting inadequate seizure control. Conclusions: Our data show relatively poor prognosis of SHE on medical therapy. Its outcome is significantly related to disease duration at the time of diagnosis. Abbreviation: SHE = Sleep related hypermotor epilepsy.
