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 ...
[1] Visuospatial processing refers to the "ability to perceive, analyze, synthesize, manipulate and transform visual patterns and images". [2] Visuospatial working memory (VSWM) is involved in recalling and manipulating images to remain oriented in space and keep track of the location of moving objects. [2] Early impairment in visuospatial ...
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 ...
DOG activates 2, and inhibits 1 letters in FOG. – +2 DOG activates 1, and inhibits 2 letters in D AN. – +1 The consistency of this model to agnosia is shown by evidence that bilateral lesions to the superior temporal sulcus produces 'pure word deafness' (Kussmaul, 1877), or as it is understood today, speech agnosia.
Constructional apraxia is a neurological disorder in which people are unable to perform tasks or movements even though they understand the task, are willing to complete it, and have the physical ability to perform the movements. [1]
A common method in quick detection of visuospatial extinction is a Finger Confrontation Model. Utilized as standard bedside evaluation, the task requires the patient to indicate (either verbally or by pointing) in which visual field the doctor's hand or finger is moving, while the doctor makes a wiggling motion with his index.

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 ...
