Studies have narrowed the area of the brain that, when damaged, causes visuospatial dysgnosia to the border of the occipito-temporoparietal region. [1] Predominantly, lesions (damage, often from stroke) are found in the angular gyrus of the right hemisphere (in people with left-hemisphere language), and are usually unilateral, meaning in one hemisphere of the brain.
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 ...
Construction problems are usually caused by visual perception deficits. They require normal vision and the ability to execute a series of motor activities. When looking at performance, it is important to consider perceptual and executive functioning. A patient with trouble visually recognizing patterns or spatial relations may have difficulty ...
Occupational therapy is defined by the American Occupational Therapy Association (AOTA) as "Occupational therapy practitioners in pediatric settings work with children and their families, caregivers and teachers to promote participation in meaningful activities and occupations". In childhood, these occupations may include play, school and ...
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]
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).
Visual extinction is a neurological disorder which occurs following damage to the parietal lobe of the brain. It is similar to, but distinct from, hemispatial neglect . Visual extinction has the characteristic symptom of difficulty to perceive contralesional stimuli when presented simultaneously with an ipsilesional stimulus, but the ability to ...
The visual cortex located in the occipital lobe of the brain is that part of the cerebral cortex which processes visual information. [26] Cortical blindness refers to any partial or complete visual deficit that is caused by damage to the visual cortex in the occipital lobe. Unilateral lesions can lead to homonymous hemianopias and scotomas.
