The purpose of this study was to analyze the facial recognition skills of patients diagnosed with Probable Alzheimer's Disease (AD). The performance of 181 AD patients was evaluated to address their ability to: analyze visual forms, to discriminate individual faces, and to recognize and name familiar famous faces. The results of the study demonstrate that the ability to analyze visual information is more vulnerable early in dementia than is the ability to discriminate individual faces. The inability to recognize familiar faces among the AD patients was related to impairments of their lexical/semantic system, rather than to a specific defect in facial discrimination. These data are fully consistent with existing models of face processing and recognition, and suggest that the recognition defect in AD is related to the naming component of face recognition, rather than the perceptual component.
本研究的目的是分析被诊断为疑似阿尔茨海默病（AD）患者的面部识别技能。对181名AD患者的表现进行评估，以了解他们分析视觉形式、辨别个人面孔以及识别和说出熟悉的名人面孔的能力。研究结果表明，在痴呆症早期，分析视觉信息的能力比辨别个人面孔的能力更容易受到损害。AD患者无法识别熟悉面孔与他们词汇/语义系统的损伤有关，而不是面部辨别方面的特定缺陷。这些数据与现有的面部处理和识别模型完全一致，并表明AD中的识别缺陷与面部识别的命名成分有关，而不是感知成分。
