Language assessment of a Farsi-Norwegian bilingual speaker with aphasia.

The increased occurrence of strokes combined with the high incidence of bilingualism in many regions of the world has led to an increasing number of bilingual adults with aphasia. The literature on bilingual aphasia shows the need for valid, comprehensive and reliable assessment tools for diagnostic and treatment purposes. In spite of a growing number of case studies of bilingual speakers with aphasia, there is still a need for more studies of speakers with different language combinations.
