| definition |
Definition: “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”. |

| Exclusion_criteria |
We scored as TRUE: lack of recognition; mistakes in recognition (e.g. patient recognized another man as her husband); did not recognize friend/family (prosopagnosia); agnosia. We did NOT score: disorientation. This was scored separately as ‘Disorientation’. [Note: this may be ambiguous, so use your best judgement when choosing to score as ‘impaired recognition’ versus ‘disorientation (in place)’. Generally, if the word recognition is named, you would score it here]. CAUTION: We have thought about dividing this parameter into more than just this one parameter: ‘visual agnosia’ and other symptoms of posterior cortical atrophy. However, in the clinical summaries of the NBB, too often it was only described as agnosia, and not the specific type of agnosia, and certainly not more specific information about visual impairments. Researchers must be aware of the broad interpretation of the term ‘agnosia’. |
