Word Spy网站对digital dementia的解释为“Impaired memory and cognitive functioning due to the extended use of digital devices.”(因持续长时间使用数字设备而导致记忆力和认知功能受损.)rn韩国《朝鲜日报》(The Chosunilbo)网站2005年1月28日在“You Too May Have Digital Dementia”(《你或许也有数字痴呆症》)一文中最早使用该表达方式.这篇文章写道,“Digital dementia is when people rely on digital devices like personal computers or cellular phones to the extent that they cannot even recall their own phone numbers.”(数字痴呆症是指人们对个人计算机或手机等数字设备的依赖到了甚至想不起自己电话号码的程度.)
