Purpose: To evaluate the relative frequency of regional polyspikes in focal epilepsies secondary to cortical dysplasia. Method: We performed a data search for the term „regional polyspikes“ in the data base of our Epilepsy Monitoring Unit. Patients with generalized epilepsies and Lennox-Gastaut syndrome were excluded. Regional interictal epileptiform discharges were recorded in 514 patients with non-invasive EEG. Results: We identified 29 patients with regional polyspikes and focal epilepsies. Another 485 patient showed regional epileptiform discharges other than polyspikes. The polyspikes were significantly mor…
