    Abstract:
    The aim of this study is to further clarify ictal electroencephalographic findings of patients with benign partial epilepsy in infancy in order to better understand its neurophysiologic features. The study group consisted of 13 infants with definite benign partial epilepsy in infancy, in whom ictal electroencephalograms were recorded and its benignity was confirmed at 8 years or more. The seizure manifestation was reviewed on the basis of video findings in eight patients in whom simultaneous video-electroencephalography recording was available. In the other five patients, the seizure manifestations were determined according to the observations of physicians, nurses, or technicians. Thirteen seizures from eight patients were complex partial, and six seizures from six patients were secondarily generalized ones. Ictal discharges at the onset of a seizure were focal in all seizures. The site of the origin of seizures was in the temporal area in 10 of 13 complex partial seizures, whereas it was in the parietal or occipital area in all 6 secondarily generalized seizures. Among 13 complex partial seizures, paroxysmal discharges remained focal throughout the seizures in 6 seizures, whereas they spread to one hemisphere in the other 7 seizures. Motion arrest or decreased responsiveness was uniformly observed. Lateral eye deviation was commonly recognized in complex partial seizures, whereas head rotation was observed only in seizures in which hemispheric propagation of ictal discharges was observed. Ictal electroencephalographic findings of patients with benign partial epilepsy in infancy were relatively uniform, suggesting the homogeneity of patients with benign partial epilepsy in infancy.
