Prosopagnosia (from Greek prósōpon, meaning "face", and agnōsía, meaning "non-knowledge"), [2] also known as face blindness, [3] is a cognitive disorder of face perception in which the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing (e.g. object ...
Prosopamnesia (Greek: προσωπον = "face", αμνησια = forgetfulness) is a selective neurological impairment in the ability to learn new faces. There is a special neural circuit for the processing of faces as opposed to other non-face objects.
Prosopagnosia (or "face blindness") is a category-specific visual object agnosia, specifically, impairment in visual recognition of familiar faces, such as close friends, family, husbands, wives, and sometimes even their own faces.
Prosopagnosia is the inability to recognize faces but is believed to stem from damage to the ventral route of the visual system. Whereas covert recognition is shown in people that lost their ability to recognize faces, implying an intact ventral limbic structure projecting to the amygdala.
There are two different varieties of prosopagnosia: Developmental prosopagnosia, meaning a person has developed the condition without having suffered any injury to their brains, and acquired ...
Can COVID-19 cause face blindness? A new case study finds evidence of prosopagnosia and other neuropsychological problems in a 28-year-old long-COVID patient.
Associative agnosia is associated with damage to both the right and left hemispheres at the occipitotemporal border. [22] A specific form of associative visual agnosia is known as prosopagnosia. Prosopagnosia is the inability to recognize faces.
The fusiform face area is also necessary for successful face detection and identification. This is supported by fMRI activation and studies on prosopagnosia, which involves lesions in the fusiform face area. [34] [35] [36] [37] [38] The occipital face area is located in the inferior occipital gyrus.
These variants of visual agnosia include prosopagnosia (inability to recognize faces), pure word blindness (inability to recognize words, often called "agnosic alexia" or "pure alexia"), agnosias for colors (inability to differentiate colors), agnosias for the environment (inability to recognize landmarks or difficulty with spatial layout of an ...
Prosopagnosia, also called face blindness, is a disorder that results in the inability to recognize or discriminate between faces. It can often be associated with other forms of recognition impairment, such as place, car, or emotional recognition. [18]
