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. [4]
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]
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
Simultanagnosia (or simultagnosia) is a rare neurological disorder characterized by the inability of an individual to visually perceive more than a single object at a time. . This type of visual attention problem is one of three major components (the others being optic ataxia and optic apraxia) of Bálint's syndrome, an uncommon and incompletely understood variety of severe neuropsychological ...
Visual thinking, also called visual or spatial learning or picture thinking, is the phenomenon of thinking through visual processing. [1] Visual thinking has been described as seeing words as a series of pictures.
Sense of direction is the ability to know one's location and perform wayfinding. [1] [2] It is related to cognitive maps, spatial awareness, and spatial cognition. [3]Sense of direction can be impaired by brain damage, such as in the case of topographical disorientation.
The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in linguistics, psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science.
