Diagnosis of Post-Stroke Aphasia: A Review of Language Tests in Korea.

Aphasia is one of the most serious cognitive impairments in stroke patients. An accurate diagnosis of aphasia is important for early interventions that optimize patients' functional status. Therefore, we present a review of the aphasia assessment tools currently available in Korea. Aphasia is usually evaluated using a standardized comprehensive assessment battery to establish the diagnosis of aphasia, its severity, and the treatment plan. Before a comprehensive language test, a brief screening test for aphasia can be useful to identify whether any further assessment is necessary. Several standardized evaluation tools are readily available in Korea. The Paradise-Korean version of the Western Aphasia Battery (PK-WAB) is a commonly used comprehensive aphasia test for determining the presence, type, and severity of aphasia. The Korean version of the Boston Naming Test (K-BNT) is an in-depth test to evaluate naming ability. Several screening tests, such as the Korean version of the Frenchay Aphasia Screening Test (K-FAST), the Screening Test for Aphasia and Neurologic Communication Disorders (STAND), and Semantic Verbal Fluency (SVF), can be applied to identify patients at risk in terms of language performance. Depending on the outcome of these tests, patients can be referred for further evaluation.
