Spike like EEG artefacts due to electrostatic discharge (case report)

Epileptic discharges can be elicited through different stimuli. In conscious patients hyperventi-lation and intermittent photic stimulation is used, in comatose patients other modalities such as reagebi-lity to auditory, tactile and visual stimuli are tested. We report of a 67-year-old female patient, in whom a left craniotomy had been done due to a subdural haematoma. The patient, who was initially awake with incomplete Broca aphasia became comatose. The CT scan was unchanged but the EEG did show new developed periodic lateralised epileptiform discharges (PLED). To suppress the PLED status the patient was narco…
