![]() It is usually associated with video recording even though the word “video” is not used Įpilepsy monitoring and EEG monitoring are general terms that specify neither what is monitored (video or not) nor for how long, and probably should not be used It does not necessarily include video, and there is no definition of how many hours constitute “long term”. Long-term monitoring: this term is confusing because it only refers to duration, but it is often used implying the presence of video. Video-EEG monitoring: this is usually assumed to be inpatient and prolonged, but really does not have to be either it can be short or long, inpatient or ambulatory. Prolonged EEG may also mean extended recording in order to obtain sleep.Īmbulatory EEG: outpatient recording, usually for 1–3 days but duration varies, with or without video Prolonged EEG (1–2 hours): as for routine EEG above, this can be performed with or without video. The most commonly used activation procedures are photic stimulation, hyperventilation and sleep deprivation (staying up late the night before) Often this is performed with standard “activation procedures” that increase the yield for capturing interictal epileptiform discharges (IEDs) or even seizures. Routine (or standard) EEG: 20–30 minutes, usually without video (but can easily be added).
