Spatial Agraphia

  title={Spatial Agraphia},
  author={Alfredo Ardila and Monica Rosselli},
  journal={Brain and Cognition},
Twenty-one patients with right hemisphere damage were studied (11 men, 10 women; average age = 41.33; age range 19-65). Subjects were divided into two groups: pre-Rolandic (6) and retro-Rolandic (15) right hemisphere damaged patients. A special writing test was given to each patient. The writing errors observed included literal substitutions, feature omissions and additions, letter omissions and additions, inability to maintain horizontal writing, inappropriate grouping and fragmentation of… Expand

Calculation abilities in right hemisphere damaged patients are disrupted as a result of visuospatial defects that interfere with the spatial arrangement of numbers and the mechanical aspects of mathematical operations. Expand
Progressive Agraphia, Acalculia, and Anomia: A Single Case Report
A case of a 50-year-old, right-handed female, monolingual native Spanish-speaker with a university-level education and cognitive changes is reported, which illustrates the progression of focal cognitive defects over time and the spread of abnormalities to other domains. Expand

Several types of spatial dyslexia with an attentional approach are described, and a model of attention dissociating modulation, selection control, and selection positioning can help in understanding these reading disorders. Expand
Acquired dysgraphia in adults following right or left-hemisphere stroke
The fact that lexical dysgraphia was also diagnosed in a patient with RHD suggests that these individuals may develop writing impairments due to damage to the lexical route, leading to heavier reliance on phonological processing. Expand
Language-specific Dysgraphia in Korean Patients with Right Brain Stroke: Influence of Unilateral Spatial Neglect
Unilateral spatial neglect influences copy writing system of Korean language in patients with right brain stroke, and specific dysgraphia features such as a right side space omission and a vertical stroke addition in Koreanright brain stroke patients are identified. Expand
Afferent Dysgraphia after Right Cerebral Stroke: An Autonomous Syndrome?
The present study demonstrates that afferent dysgraphia is an autonomous clinical entity and that it results from a selective impairment of a mechanism whose function is that of comparing the information about the number of letters and strokes specified at the level of letter motor programs and the actual number of movements already realized.

Crossed-Brain Representation of Verbal and Nonverbal Functions
A 74-year-old, left-handed man presented with a rapidly evolving loss of strength in his right leg associated with difficulty in walking and an extensive left hemisphere tumor, which revealed crossed-brain representations of verbal and nonverbal functions. Expand
It is proposed that complex aspects of writing, such as planning, narrative coherence, and maintained attention, are significantly disturbed in cases of impairments of executive functions. Expand
Prism adaptation improves spatial dysgraphia following right brain damage
Positive effects of prism adaptation on spatial dysgraphia, in a neglect patient following right brain damage, reinforce the idea that the process of Prism adaptation may activate brain functions related to multisensory integration and higher spatial representations and show a generalization at a functional level.

Alexia and agraphia in Spanish.
In Spanish-speaking aphasia patients, difficulties in reading and writing are similar to oral language difficulties; this similarity of performance is mostly based on severity rather than the participants' patterns of errors. Expand
