What is Agnosia?
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.
