Processing of metaphors in transcortical motor aphasia

Great emphasis has been placed on the right hemisphere, due to its possible selective contribution, in the processing of metaphorical statements.

description Great emphasis has been placed on the right hemisphere, due to its possible selective contribution, in the processing of metaphorical statements. OBJECTIVES: To describe the processing of metaphors in the case of a patient with transcortical motor aphasia, using specific tests for patients with encephalic injuries of the right hemisphere, and to contribute to the discussion on the inter-hemispheric relationships associated with this function. METHODS: A 54 year-old man with transcortical motor aphasia was evaluated three years after a left hemisphere stroke. The tasks of comprehension of metaphors were based on the subtest Metaphor Comprehension Task of the Montreal Evaluation of Communications Scale (MEC). Two metaphor comprehension tests were applied, in 45-minute sessions with a 48 hour interval between each. Test 1 involved comprehension of the metaphors according to the options offered, and Test 2 the comprehension of metaphors measured by response time and visual field. RESULTS: Although the right hemisphere was not affected by the stroke in this case, difficulties were observed in the processing of metaphors. CONCLUSIONS: This study suggests that the left hemisphere participates in the processing of figurative meanings. The adaptability of the brain can also re-accommodate the uninjured areas of the brain, causing the dynamic of the brain to be modified. As a result, deducing cerebral functions based on clinical data can be problematic. The value of this study is that it can contribute to clinical aspects of language rehabilitation.
