Abstract

Objective: To analyze cognitive functions of post-stroke aphasia patients compared to patients having right hemispheric stroke and left hemispheric lesions without aphasia, and to look for a relationship between cognitive deficits and aphasia severity. Methods: Thirty-six patients with right hemispheric stroke (group 1), 32 with left hemispheric lesion without aphasia (group 2), and 26 left hemispheric stroke patients with aphasia (group 3) completed a set of tests in the computerized neurocognitive function batteries for attention, executive function and intelligence and Korean version of Western Aphasia Battery. Data analyses explored cognitive characteristics among the three groups and the correlation between cognitive deficits and aphasia severity. Results: Right hemispheric and left hemispheric stroke patients without aphasia showed similar findings except for digit span forward test. Cognitive tests for working memory and sustained attention were significantly impaired in the aphasic patients, but intelligence was shown to be similar in the three groups. Significant correlation between cognitive deficit and aphasia severity was only shown in some attention tests. Conclusion: Cognitive deficits may be accompanied with post-stroke aphasia and there are possible associations between language and cognitive measures. Therefore, detection and treatment towards coexisting cognitive impairment may be necessary for efficient aphasia treatment.
