Stimulus-induced diffuse voltage attenuation (SIDVA): a previously undescribed EEG pattern in a critically ill child

We report the case of a 15-month-old critically ill child with stimulus-induced diffuse voltage attenuation, a previously unreported electroencephalogram pattern. No clinical evidence of seizure activity was associated with these EEG changes. The patient went on to have a full recovery. This case suggests that critically ill children have distinct stimulus induced electrographic patterns from those seen in adults. Additional research is needed to define the significance of these patterns.
