[Usefulness of the "token test" in the diagnosis of aphasia]

The authors describe a method of aphasia examination, so called Token test, not known in Poland. The method is particularly useful for evaluation of speech perception disturbances, and it may also be used in cases of aphasia with expression disturbances. Speech examination by the Token test was carvied out in 45 patients with damage to the predominating hemisphere caused by stroke and the obtained results were compared with qualitative-quantitative aphasia estimation by the conventional method (determination of spontaneous speech, ordinate speech, denomination, repetition, reading, writing and understanding). A considerable agreement of the results obtained by both methods (correlation coefficient 0.80) indicates the usefulness of the test for clinical practice, especially in cases of diagnostically uncertain aphasia.
