| Research Abstract |
It is difficult to distinguish between acute encephalopathies with poor prognosis and febrile seizures or epileptic seizures with favorable prognosis using visual electroencephalography (EEG) analysis. Therefore, digital EEG analysis was applied to distinguish between them. Child patients with acute encephalopathies, febrile seizures, or epileptic seizures were the subjects and digital EEGs recorded during acute periods were used for this study. Neurological sequelae were graded into 6 categories: vegetative state, profound mental retardation, severe retardation, moderate retardation, mild retardation , and normal. 1) The EEG power spectra of the theta band was decreased in vegetative state at the frontal region. 2) Frontal-posterior EEG coherence was low in mild to moderate mental retardation groups and high in normal group. Therefore, digital EEG analysis would be a useful tool to diagnose acute encephalopathy with poor prognosis.
