Abstract

Objective: To evaluate the types and severity of subcortical aphasia after stroke and to determine the predictors of the degree of aphasic impairment.

Methods: Medical records of 38 patients with post-stroke subcortical aphasia (19 males; mean age, 61.7±13.8 years) were reviewed retrospectively with respect to the following tests: the Korean version of the Western Aphasia Battery (K-WAB), the Korean version of the Modified Barthel Index (K-MBI), and the Fugl-Meyer Index (FMI). The severity of aphasia was evaluated by the aphasia quotient (AQ) and the language quotient (LQ).

Results: Anomic aphasia was the most frequent type of aphasia (n=15, 39.5%), and the lesion most frequently observed in subcortical aphasia was located in the basal ganglia (n=19, 50.0%). Patients with lesions in the basal ganglia exhibited the lowest scores on the FMI for the upper extremities (p=0.04). Severity of aphasia was significantly correlated with the K-MBI (Pearson correlation coefficient: γ=0.45, p=0.01 for AQ and γ=0.53, p=0.01 for LQ) and FMI scores for the lower extremities (γ=0.43, p=0.03 for AQ and γ=0.49, p=0.05 for LQ). In a multivariate logistic regression analysis, K-MBI remained the only explanatory variable closely associated with aphasia severity.

Conclusion: This study showed the general characteristics of post-stroke subcortical aphasia, and it revealed that K-MBI was an associated and explanatory factor for aphasia severity.
