NINDS:43 Agnosia is a rare disorder characterized by an inability to recognize and identify objects or persons. People with agnosia may have difficulty recognizing the geometric features of an object or face or may be able to perceive the geometric features but not know what the object is used for or whether a face is familiar or not. Agnosia can be limited to one sensory modality such as vision or hearing. For example, a person may have difficulty in recognizing an object as a cup or identifying a sound as a cough. Agnosia can result from strokes, dementia, developmental disorders, or other neurological conditions. It typically results from damage to specific brain areas in the occipital or parietal lobes of the brain. People with agnosia may retain their cognitive abilities in other areas.

MalaCards based summary: Agnosia, also known as dyspraxia, is related to associative agnosia and pain agnosia. An important gene associated with Agnosia is BBS2 (Bardet-Biedl syndrome 2), and among its related pathways are Signaling by NOTCH1 PEST Domain Mutants in Cancer and Wnt / Hedgehog / Notch. Affiliated tissues include brain, parietal lobe and eye, and related mouse phenotypes are taste/olfaction and hearing/vestibular/ear.

Disease Ontology:8 A communication disorder that is a loss of ability to recognize objects, persons, sounds, shapes, or smells while the specific sense is not defective nor is there any significant memory loss.

NIH Rare Diseases:42 Agnosia is characterized by an inability to recognize and identify objects and/or persons. symptoms may vary, according to the area of the brain that is affected. it can be limited to one sensory modality such as vision or hearing; for example, a person may have difficulty in recognizing an object as a cup or identifying a sound as a cough. agnosia can result from strokes, traumatic brain injury, dementia, a tumor, developmental disorders, overexposure to environmental toxins (e.g., carbon monoxide poisoning), or other neurological conditions. visual agnosia may also occur in association with other underlying disorders. people with agnosia may retain their cognitive abilities in other areas. treatment of primary agnosia is symptomatic and supportive; when it is caused by an underlying disorder, treatment of the disorder may reduce symptoms and help prevent further brain damage. last updated: 4/22/2011
