Prosopagnosia, [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 discrimination) and intellectual functioning (e.g., decision-making) remain intact.
Asomatognosia (also Somatoagnosia) is a neurological disorder characterized as loss of recognition or awareness of part of the body. [1] [2] The failure to acknowledge, for example, a limb, may be expressed verbally or as a pattern of neglect. The limb may also be attributed to another person, a delusion known as somatoparaphrenia. However ...
Initially many individuals with a form of agnosia are unaware of the extent to which they have either a perceptual or recognition deficit. This may be caused by anosognosia which is the lack of awareness of a deficit. This lack of awareness usually leads to a form of denial and resistance to any form of help or treatment.
Alexithymia, also called emotional blindness, [1] is a neuropsychological phenomenon characterized by significant challenges in recognizing, expressing, feeling, sourcing, [2] and describing one's emotions.
Thumos, also spelled Thymos (Ancient Greek: θυμός), is the Ancient Greek concept of ' spiritedness ' (as in "a spirited stallion" or "spirited debate"). [1] The word indicates a physical association with breath or blood and is also used to express the human desire for recognition.
Thus, those with object recognition impairments are more likely to have acquired damage to the dorsal cortex. [3] While astereognosis is characterized by the lack of tactile recognition in both hands, it seems to be closely related to tactile agnosia (impairment connected to one hand). Tactile agnosia observations are rare and case-specific.

Visual agnosia is an impairment in recognition of visually presented objects. It is not due to a deficit in vision (acuity, visual field, and scanning), language, memory, or intellect. [ 1 ] While cortical blindness results from lesions to primary visual cortex, visual agnosia is often due to damage to more anterior cortex such as the posterior ...
