The authors report the MRI, interictal electroencephalogram (EEG) and clinical features of seven patients with epilepsy with episodic darkness as the main clinical feature. Seven patients with epilepsy seizures were transient monthesome to highlight the clinical manifestations, aged 7 to 20 years, the average attack age of 13.3 years. Head MRI examination of all patients included axial, coronal and sagittal T 1 and T 2 weighted imaging. In each case, a routine EEG examination was performed. Cases 1, 4 and 5 were also monitored by remote EEG. Case 2 had seizures during the EEG examination.
