The present study was undertaken to clarify how we should assess the necessity of close follow-up in each case, when we first examine an infant with ankle clonus within the first year of life. The neurologic prognoses of 169 infants who had exhibited ankle clonus at least once during the first year of life were reviewed in relation to the age at examination(More)
We report a clinico-electroencephalographical follow-up study on a male patient with early myoclonic encephalopathy. Frequent massive and fragmentary myoclonic seizures, and myoclonic-clonic seizures were the initial symptoms at the age of 3 days. EEG revealed a suppression-burst pattern at the onset in which burst phases often coincided with myoclonic(More)
PURPOSE In infants, benign convulsions can be triggered by febrile illness or mild diarrhea such as Rotavirus gastroenteritis. The triggering mechanism of these convulsions is still unknown. In spite of several reports concerning clinical features, the ictal EEG recordings were rarely analyzed by a video-EEG monitoring system. To reveal a clue for the(More)
Induced microseizures (IMS) were observed in a 5-month-old girl with symptomatic West syndrome. The seizures occurred following the suppression of infantile spasms with adrenocorticotropic hormone therapy and disappeared following the cessation of clonazepam administration. The ictal manifestations consisted of periods of irregular respiration, and(More)
A Japanese male with mosaicism of ring chromosome 14 and chromosome 14 monosomy is described. He demonstrated the characteristic morphologic features of ring chromosome 14, in addition to mental retardation and epileptic seizures. Clusters of complex partial seizures, one of which originated in the left frontocentral region on electroencephalographic(More)
Neuropathological examination of a 3-day-old female with thanatophoric dysplasia revealed abnormal sulci with polymicrogyria and neuronal heterotopia in the temporal lobes and cerebellar hypoplasia. Rapid Golgi stainings showed immature or maldeveloped neurons with short dendrites and a reduced number of spines in the cerebral cortex, and abnormal neurons(More)
Secondary sensory seizures (SSS) are very rare epileptic seizures. A 14-year-old male patient with habitual painful seizures of the backs of both hands since the age of four is reported. The painful seizures were rarely followed by impairment of consciousness. Ictal EEG showed 4 to 6Hz rhythmic waves over the right anterior and mid-temporal area following(More)
The neurologic outcomes of 61 children with asymmetric plantar grasp responses during infancy were evaluated during a follow-up period of 2.8-11.9 years (mean: 6.1 years). They all had perinatal risk factors and/or neurologic signs except for asymmetric plantar grasp responses recorded during infancy. The outcomes consisted of cerebral palsy in 38, delay in(More)
