The misidentification of a familiar person or of oneself may occur as a complication of dementia. Seven patients experienced alterations of the sense of familiarity for a familiar object or place, for the misidentified person in a novel role, for personal characteristics, or for unfamiliar events as familiar. Five of these had persecutory delusions. These cases suggest that person misidentification in dementia begins with an altered sense of familiarity for a familiar person from a mismatch of new perceptions with past memories. They are sustained by paranoid elaboration or confabulatory rationalisation of a double.
将熟悉的人或自己认错可能作为痴呆症的一种并发症出现。七名患者对熟悉的物体或地点、对以新角色出现的被认错的人、对个人特征或对原本不熟悉却被当作熟悉的事件产生了熟悉感的改变。其中五人有被害妄想。这些病例表明，痴呆症中的认错始于对熟悉的人因新感知与过去记忆不匹配而产生的熟悉感改变。它们通过对替身的偏执性详述或虚构性合理化得以持续。
