Trend EEG revealed generalized 5–6 Hz theta with admixed 2–3 Hz delta frequency slowing. There was evidence of multifocal, independently occurring, sharp waves in the bilateral cerebral hemispheres occurring most prominently with stimulation. With stimulation, discharges occur with 1–2 Hz periodicity. Additionally, frequent generalized triphasic waves were seen. Triphasic waves were seen in addition to generalized slowing of the background activity. These collective findings in the setting of underlying diffuse cerebral dysfunction suggested the potential for seizures to arise.
