Abstract
|
|
|
Background: The term “transcortical aphasia” is applied to primary lesions not involving the receptive and expressive language areas, but rather the areas connected to the association cortex. By definition, patients with transcortical aphasia can repeat what they have heard, but they have difficulty producing spontaneous speech or understanding speech. This paper reports the clinical features of stroke patients with transcortical aphasia to delineate the language profiles of its subtypes.
Methods: Eighty patients with stroke were divided into three subtypes of transcortical aphasia: transcortical sensory aphasia, transcortical motor aphasia, and mixed transcortical aphasia. A Korean version of the Western Aphasia Battery was used to compare the subdomains of language ability among the three groups.
Results: The patients showed a relatively preserved repetition ability, but the performances in repetition and generative naming, and the aphasia quotient were highest in the transcortical sensory aphasic group, followed by the transcortical motor aphasic and mixed transcortical aphasic groups.
Conclusions: The present study provides detailed information on the language profiles of the three subtypes of transcortical aphasia, which can be differentiated based on the aphasia quotient and generative naming scores.
