•Patients with cortical involvement on brain CT present higher risk of late seizures.•Epileptiform abnormalities are associated with a 6-fold increased risk of epilepsy.•Focal slowing correlates with cortical involvement and higher remote seizure rate.•Early routine EEG and neuroimaging provide pote...
