Current concepts in adult aphasia

Abstract
This paper provides a review of recent research from the areas of speech and language pathology, cognitive psychology, psycholinguistics, neurology, and rehabilitation medicine which is used to refine and extend current definitions of aphasia. Evidence is presented from these diverse disciplines, which supports a multimodality, performance-based, verbal and non-verbal, cortical and subcortical, and cognitively multidimensional view of aphasia. A summary of current practice in the assessment and treatment of adult aphasia is summarized.
