For patients with visuospatial dysgnosia, the information input may be strengthened by adding tactile, motor, and verbal perceptual inputs. This comes from the general occupational therapy practice of teaching clients with intellectual dysfunctions to use the most effective combinations of perceptual input modalities, which may enable them to complete a task.
Nonverbal learning disorder (NVLD or NLD) is a proposed neurodevelopmental disorder characterized by core deficits in nonverbal skills, especially visual-spatial processing. People with this condition have normal or advanced verbal intelligence and significantly lower nonverbal intelligence. [ 3 ]
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 ...
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 ...
Three of the patients showed improvement in deficits without any kind of formal treatment, though executive function was still found to be one standard deviation below average. In one patient, the deficits worsened over time. This patient had cerebellar atrophy and worsened in visual spatial abilities, concept formation, and verbal memory. [2]
Bálint's syndrome symptoms can be quite debilitating since they impact visuospatial skills, visual scanning and attentional mechanisms. [8] Since it represents impairment of both visual and language functions, it is a significant disability that can affect the patient's safety—even in one's own home environment, and can render the person incapable of maintaining employment.

Sensory processing disorder is present in many people with dyspraxia, autism spectrum disorder, and attention deficit hyperactivity disorder (ADHD). Individuals with SPD may inadequately process visual , auditory , olfactory (smell), gustatory (taste), tactile (touch), vestibular (balance), proprioception (body awareness), and interoception ...
Prism adaptation can be used to rehabilitate the visuo-spatial deficits of neurological disorders such as unilateral neglect.It has become clear that with respect to being used as a long-term rehabilitative tool, prism adaptation is only effective when it is repeated over many sessions and with sufficiently strong prism goggles (Newport and Schenk, 2012).
