High density EEG (HD-EEG) recordings utilize a higher spatial sampling of scalp electrodes than a standard 10–20 low density EEG (LD-EEG) montage. Although several studies have demonstrated improved localization of the epileptogenic cortex using HD-EEG, widespread implementation is impeded by cost, setup and interpretation time, and lack of specific or sufficient procedural billing codes. In spite of these barriers, HD-EEG has been in use at several institutions for years. These centers have noted utility in a variety of clinical scenarios where increased spatial resolution from HD-EEG has been required, justifying the extra time and cost. We share select scenarios from several centers, utilizing different recording techniques and software, where HD-EEG provided information above and beyond the standard LD-EEG. We include seven cases where HD-EEG contributed directly to current clinical care of epilepsy patients and highlight two novel techniques which suggest potential opportunities to improve future clinical care. Cases illustrate how HD-EEG allows clinicians to: Case 1) lateralize falsely generalized interictal epileptiform discharges (IEDs); Case 2) Improve localization of falsely generalized epileptic spasms; Cases 3–4) Improve localization of IEDs in anatomic regions below the circumferential limit of standard LD-EEG coverage; Case 5) Improve non-invasive localization of the seizure onset zone in lesional epilepsy; Cases 6–7) Improve localization of the seizure onset zone to guide invasive investigation near eloquent cortex; Case 8) Identify epileptic fast oscillations; Case 9) Map language cortex. Together, these nine cases illustrate that using both visual analysis and advanced techniques, HD-EEG can play an important role in clinical management.
