"' Apperceptive agnosia "'is failure in recognition that is due to a failure of perception.
12.
Tasks requiring copying, matching, or drawing simple figures can distinguish the individuals with apperceptive agnosia because they cannot perform such tasks.
13.
While it is established that semantics plays a large role in apperceptive agnosia deficits, it is not agreed upon how semantics alter recognition processes.
14.
When referring to apperceptive agnosia, visual and object agnosia are most commonly discussed; This occurs because apperceptive agnosia is most likely to present visual impairments.

16.
Because primary visual processing was intact, Lissauer considered the possible diagnostic distinction between deficits in perception ( apperceptive agnosia ) and in recognition ( associative agnosia ).
17.
Apperceptive agnosia is failure of object recognition even when the basic visual functions ( acuity, color, motion ) and other mental processing, such as language and intelligence, are normal.
18.
In addition to verbal and nonverbal auditory agnosia, there are cases of auditory apperceptive agnosia where patients are unable to recognize music in the absence of sensory, intellectual, and verbal impairments.
19.
If a person is unable to recognize objects because they cannot perceive correct forms of the objects, although their knowledge of the objects is intact ( i . e . they do not have anomia ), they have apperceptive agnosia.
20.
Visual agnosia may be present in early stages of AD and can often act as an indicator of AD . Apperceptive agnosia results from diffuse cortical pathology of AD . There is early involvement in the hippocampus and the entorhinal cortex followed by a spread to adjacent areas with neurofibulary tangles ( NFT ).
