However, the incidence, associated factors and influence on outcome of interictal epileptic discharges and subclinical electrographic seizures in the acute phase of stroke are unknown. Methods In this prospective study, 35 patients underwent long-term video-EEG monitoring within 3 days after intracerebral haemorrhage or ischemic stroke. Epileptic activity on the EEG was analysed and correlated with clinical and neuroradiological patient characteristics, the occurrence of clinical seizures and outcome. Results Epileptic activity, a term comprising electrographic seizures, spikes and spike waves, was seen on the EEGs of 8/35 (23%) patients. 3/35 (9%) of patients had electrographic seizures and spikes or spike waves were seen in 6/35 (17%) of subjects. Ictal electrographic activity and early clinical seizures (<7 days post-stroke) were significantly correlated (p=0.018) in patients with ischemic stroke. No other significant associations were found between the occurrence of epileptic discharges and clinical or radiological features, nor with outcome. Conclusion In this study, epileptic discharges were frequently seen in the acute phase post-stroke. Ictal electrographic activity was associated with the occurrence of early clinical seizures. However, there was no association between electroencephalographic epileptic activity and outcome.
