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.

Using an analog clock to tell time is difficult for people with symptoms of NVLD. Considered to be neurologically based, [11] [12] nonverbal learning disorder is characterized by: impairments in visuospatial processing; discrepancy between average to superior verbal abilities and impaired nonverbal abilities, such as: visuoconstruction
Visuospatial skills are needed for movement, depth and distance perception, and spatial navigation. [1] Impaired visuospatial skills can result in, for example, poor driving ability because distances are not judged correctly or difficulty navigating in space such as bumping into things.
Nonverbal learning disorder (NLD or NVLD), a neurodevelopmental disorder thought to be linked to white matter in the right hemisphere of the brain and generally considered to include (a) low visuospatial intelligence; (b) discrepancy between verbal and visuospatial intelligence; (c) visuoconstructive and fine-motor coordination skills; (d ...
As Alzheimer’s disease is the most common form of dementia — affecting an estimated 6.7 million Americans — it’s not surprising that people who experience memory loss may suspect AD.. In ...
In particular, people with Williams syndrome experience challenges in visual-motor skills and visuospatial construction. Most affected people are unable to spatially orient themselves and many experience difficulty when given a task that requires even the most basic visual problem-solving.
Reading skills for eighth-graders hit their lowest level since testing began in 1992. Levels for fourth-graders were also near record lows as educators struggle to keep students engaged in a post ...
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.
