Visuospatial dysgnosia, along with Balint's syndrome, has been connected with Alzheimer's disease as a possible early sign of the disease. [2] Generally, the first symptom of Alzheimer's onset is loss of memory, but visual or visuospatial dysfunction is the presenting symptom in some cases [3] and is common later in the disease course.

Topographical disorientation is the inability to orient oneself in one's surroundings, sometimes as a result of focal brain damage. [1] This disability may result from the inability to make use of selective spatial information (e.g., environmental landmarks) or to orient by means of specific cognitive strategies such as the ability to form a mental representation of the environment, also known ...
In cognitive psychology, visuospatial function refers to cognitive processes necessary to "identify, integrate, and analyze space and visual form, details, structure and spatial relations" in more than one dimension. [1] Visuospatial skills are needed for movement, depth and distance perception, and spatial navigation. [1]
The researchers then concluded how important spatial ability is for STEM and as a factor in achieving advanced educational success in that field. [25] Spatial visualization is especially important in science and technology. For example, an astronomer must visually imagine the structures of a solar system, and the path of the bodies within it.

Visuospatial dysgnosia: This is a loss of the sense of "whereness" in the relation of oneself to one's environment and in the relation of objects to each other. It may include constructional apraxia, topographical disorientation, optic ataxia, ocular motor apraxia, dressing apraxia, and right-left confusion. [citation needed] Visual agnosia
The term VSTM refers in a theory-neutral manner to the non-permanent storage of visual information over an extended period of time. [1] The visuospatial sketchpad is a VSTM subcomponent within the theoretical model of working memory proposed by Alan Baddeley; in which it is argued that a working memory aids in mental tasks like planning and ...
The Corsi block-tapping test is a psychological test that assesses visuo-spatial short term working memory.It involves mimicking a researcher as they tap a sequence of up to nine identical spatially separated blocks.
Assorted diagnoses have been discussed as sharing symptoms with NVLD. In some cases, especially the form of autism previously called Asperger syndrome, the overlap can be significant; a major clinical difference is that NVLD criteria do not mention the presence or absence of either repetitive behaviors or narrow subject-matter interests, [10] which is part of the diagnostic criteria for autism ...
