Background Periodic discharges ( PD s) are well established as either periodic lateralized epileptiform discharges ( LPD s) or generalized discharges. However, PD s in the midline can currently not be adequately classified as they are not generalized and not lateralized. Aims of the study To propose a modification of the current LPD classification. Methods We here present a paradigmatic case series of three adult patients with midline LPD s. Results In our patients, ictal electroencephalography ( EEG ) recordings revealed periodic epileptiform discharges in the midline region. All three patients were non‐lesional. Conclusion We, thus, suggest to include periodic localized non‐lateralized epileptiform discharges into the term LPD s (in addition to periodic lateralized epileptiform discharges), as they can also be recorded as localized EEG phenomenon in the midline region.
