Abstract

This study was designed to explore the Chinese writing function of patients with subcortical stroke. Two cohorts of patient subjects with either the left or the right subcortical strokes, mainly putaminal hemorrhagic strokes, and one group of normal controls participated in the study. All participants received a writing test battery including the three aspects of writing function, that is, Spontaneous Writing, Writing to Dictation, and Writing from Copy, as well as a battery of non-writing linguistic tests. Comparing with normal controls revealed that writing function change occurred in both patient groups. The deficits in the patients with the left subcortical stroke essentially included Spontaneous Writing, and Writing to Dictation. These impairments were most likely secondary to aphasic disorders. The writing problem, mainly Writing from Copy, was noted in the patients with the rightsubcortical stroke. This deficit, however, was independent of the core linguistic impairment. On the basis of the results, we suggest that the lesion involving white matter in the left hemisphere probably interrupts left perisylvian cortical language organization in a manner that produces problems with spontaneous writing and writing to dictation, which are language-related, associated withlesion in the dominant hemisphere. This further suggests that left or right subcortical lesions in the putamen and surrounding white matter are associated with differential effects (language vs, non-language based effects) which are similar to such differences observed with left vs. right cortical lesions.
