Ambulatory electroencephalography (aEEG) is a technique of continuous EEG recording while ensuring maximum mobility of the patient in a more naturalistic setting. The initial technological drawbacks of aEEG have been circumvented by incorporating digital and computer technology. Some of the current devices provide the facility of synchronous video recording. Low cost, convenience, higher diagnostic yield, and the ability to capture circadian patterns are the main advantages of aEEG. It is a useful tool in the diagnosis of epilepsy and nonepileptic paroxysmal disorders. Ambulatory EEG is superior to routine EEG in capturing interictal epileptiform abnormalities particularly in relation to natural sleep. However, the use of aEEG in presurgical workup is still unclear and more research is needed. At present, the place of EEG in the decision making for antiepileptic drug withdrawal is unclear and aEEG is an ideal tool to study this research question. Well-designed studies are needed to evaluate the use of aEEG in the assessment of response to antiepileptic therapy and occupational safety. Ambulatory EEG is an underutilized tool and more research is needed to expand the horizon of its applications in clinical practice.
