Abstract

Keyboard typing is a multifunctional task related to language, visual-spatial and motor abilities. If one of these functions is impaired, difficulty during typing could occur. Here, a 64-year-old right-handed man is reported who developed a sudden typing disturbance without aphasia or neglect. Magnetic resonance imaging of the brain showed discrete acute infarcts in the border-zone regions, bilaterally, predominantly in the left hemisphere. The neuropsychiatric testing showed an impaired visual-spatial memory domain; however, other cognitive functions were all normal. These findings suggest that visual-spatial memory impairment, associated with a left frontal subcortical infarct, is a probable anatomic substrate associated with the inability to type.
