面孔失认症是一种选择性的视觉失认症，其特征是不能识别面孔的身份。既有继发于脑损伤的获得性形式，也有没有明显结构损伤的发育性形式。在这篇综述中，我们首先讨论了获得性和发展性面容失认症的诊断，以及后者所面临的挑战。第二，我们讨论的证据有关的选择性的prosopagnosic缺陷，特别是在识别其他对象，书面文字（另一个视觉对象类别，需要高专业知识），和声音。第三，我们总结了最近的研究结果的结构和功能的基础上，面孔失认症的磁共振成像，功能磁共振成像和事件相关电位。最后，我们讨论了最近的尝试在面孔失认症的面部识别康复。
Prosopagnosia is a selective visual agnosia characterized by the inability to recognize the identity of faces. There are both acquired forms secondary to brain damage and developmental forms without obvious structural lesions. In this review, we first discuss the diagnosis of acquired and developmental prosopagnosia, and the challenges present in the latter case. Second, we discuss the evidence regarding the selectivity of the prosopagnosic defect, particularly in relation to the recognition of other objects, written words (another visual object category requiring high expertise), and voices. Third, we summarize recent findings about the structural and functional basis of prosopagnosia from studies using magnetic resonance imaging, functional magnetic resonance imaging, and event-related potentials. Finally, we discuss recent attempts at rehabilitation of face recognition in prosopagnosia.
