Abstract
The clinical characteristics and electroencephalogram (EEG) findings in delirious
behavior in children with influenza were studied in order to differentiate it from
influenza-associated encephalitis/encephalopathy. Fifteen consecutive children with
delirious behavior associated with influenza were investigated. Their clinical courses
were investigated using medical records. EEG was obtained during the delirious behavior,
when possible. The body temperature during the delirious behavior was 39.0 °C or higher in 13 children. A subtle reduction of consciousness was observed in 10
children. Seizures were observed in five children. EEG revealed some mildly abnormal
findings in 13 children, including mild slowing of the background activity, insertion
of semirhythmic high voltage slow waves, and appearance of relatively high voltage
semirhythmic theta waves. The EEG findings normalized after the delirious behavior
had disappeared. EEG revealed transient and mild abnormalities in children with delirious
behavior but without encephalitis/encephalopathy, and thus might be useful for diagnostic
evaluation in such condition.
