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.
动态脑电图(aEEG)是一种在更自然的环境中确保患者最大活动能力的同时进行连续脑电图记录的技术。通过整合数字和计算机技术,aEEG最初的技术缺陷已得到克服。目前一些设备具备同步视频记录功能。低成本、便利性、更高的诊断率以及捕捉昼夜节律模式的能力是aEEG的主要优势。它是诊断癫痫和非癫痫性发作性疾病的有用工具。动态脑电图在捕捉发作间期癫痫样异常方面优于常规脑电图,尤其是在自然睡眠方面。然而,aEEG在术前评估中的应用仍不明确,需要更多研究。目前,脑电图在抗癫痫药物撤药决策中的作用尚不清楚,而aEEG是研究这一问题的理想工具。需要精心设计的研究来评估aEEG在抗癫痫治疗反应评估和职业安全方面的应用。动态脑电图是一种未得到充分利用的工具,需要更多研究来拓展其在临床实践中的应用范围。
