阿尔茨海默病患者对比敏感度不足，面部辨别能力受损。作者展示了三种不同大小的陌生面孔的照片，以增强低、中、高面部频率信息（每张面孔的周期）。AD患者仅表现出对小脸的正常识别，这表明低面部频率下的对比敏感度受损导致了他们的面部识别能力差。
People with AD have deficient contrast sensitivity and impaired face discrimination. The authors presented photographs of unfamiliar faces of three different sizes to enhance the low, middle, or high facial frequency information (cycles per face). Patients with AD demonstrated normal discrimination of small faces only, indicating that impaired contrast sensitivity at low facial frequencies contributes to their poor face discrimination.
