Investigations of two cases of the Capgras delusion found that both patients showed face-processing impairments encompassing identification of familiar faces, recognition of emotional facial expressions, and matching of unfamiliar faces. In neither case was there any impairment of recognition memory for words. These findings are consistent with the idea that the basis of the Capgras delusion lies in damage to neuro-anatomical pathways responsible for appropriate emotional reactions to familiar visual stimuli. The delusion would then represent the patient's attempt to make sense of the fact that these visual stimuli no longer have appropriate affective significance.
对两例卡普格拉妄想症患者的调查发现，两名患者均表现出面部处理障碍，包括熟悉面孔的识别、面部表情的情感识别以及陌生面孔的匹配。在这两例中，对单词的识别记忆均未受损。这些发现与以下观点一致，即卡普格拉妄想症的基础在于负责对熟悉视觉刺激做出适当情感反应的神经解剖通路受损。那么这种妄想就代表了患者试图理解这些视觉刺激不再具有适当情感意义这一事实。
