Abstract:
This report describes a female with eyelid fluttering with absence seizures, infrequent generalized tonic-clonic seizures, and mild mental retardation. Interictal and video-electroencephalography evaluations revealed normal activity while eyes were open but continuous generalized discharges with eyes closed (eyes closed induced abnormality), as well as fixation-off sensitivity. This patient is in the group of a pure and distinct clinical form of fixation-off sensitivity cryptogenic generalized epilepsy.
