Acquired dysgraphia in adults following right or left-hemisphere stroke
Objective This study aimed to assess the strengths and difficulties in word and pseudoword writing in adults with left- and right-hemisphere strokes, and discuss the profiles of acquired dysgraphia in these individuals. Methods The profiles of six adults with acquired dysgraphia in left- or right-hemisphere strokes were investigated by comparing their performance on word and pseudoword writin...
متن کاملLeft unilateral neglect or right hyperattention?
BACKGROUND Contradictory interpretations of left unilateral neglect suggest that it reflects either decreased attention toward the left or increased attention toward the right. According to the right-hyperattention postulate, increasing severity of neglect should result from an increasingly stronger bias toward the right. Thus, response times to right-sided targets should become progressively f...
متن کاملMulti-tasking uncovers right spatial neglect and extinction in chronic left-hemisphere stroke patients.
Unilateral Spatial Neglect, the most dramatic manifestation of contralesional space unawareness, is a highly heterogeneous syndrome. The presence of neglect is related to core spatially lateralized deficits, but its severity is also modulated by several domain-general factors (such as alertness or sustained attention) and by task demands. We previously showed that a computer-based dual-task par...
متن کاملDissociated neglect behavior following sequential strokes in the right hemisphere.
A 42-year-old woman suffered two focal right hemisphere strokes, sequentially damaging different components of a proposed cerebral network for the spatial distribution of attention. Her first stroke was centered in the right frontal lobe and resulted in left hemi-spatial neglect but only for tasks that emphasize exploratory-motor components of directed attention. A second stroke occurred 20 day...
متن کاملLeft hand movements and right hemisphere activation in unilateral spatial neglect: a test of the interhemispheric imbalance hypothesis.
The aim of the present study was to check one of the main assumptions of the interhemispheric imbalance hypothesis, namely, the prediction that the severity of neglect should be reduced by conditions activating the right hemisphere. To achieve this, a group of neglect patients was studied using a slightly modified version of the limb activation technique. The (verbal or visuo-spatial) nature of...
