The primary diagnosis of most cognitive disorders is clinically based, but the EEG plays a role in evaluating, classifying and following some of these disorders. There is an ongoing debate over routine use of qEEG. Although many findings regarding the clinical use of quantitative EEG are awaiting validation by independent investigators while confirmatory clinical follow-up studies are also needed, qEEG can be cautiously used by a skilled neurophysiologist in cognitive dysfunctions to improve the analysis of background activity, slow/fast focal activity, subtle asymmetries, spikes and waves, as well as in longitudinal follow-ups.
大多数认知障碍的初步诊断基于临床,但脑电图在评估、分类和跟踪其中一些障碍方面发挥着作用。关于定量脑电图的常规使用存在持续的争论。尽管许多关于定量脑电图临床应用的研究结果有待独立研究者验证,同时也需要进行确证性临床随访研究,但熟练的神经生理学家可以谨慎地将定量脑电图用于认知功能障碍,以改善对背景活动、慢/快局灶性活动、细微不对称、棘波和波的分析,以及纵向随访研究。
