Communicative clusters after a right-hemisphere stroke: are there universal clinical profiles?

Folia Phoniatr Logop. 2012;64(4):199-207. doi: 10.1159/000340017. Epub 2012 Oct 25.


Objective: The current research aimed at classifying communication profiles among right-brain-damaged adults with an intercultural perspective, and so begins to fill in a long-standing gap in the literature.

Method: The sample was made up of 112 right-brain-damaged individuals from three nationalities (Canadians, Brazilians and Argentineans). They were assessed using 13 language tasks from the Protocol MEC in Spanish, Brazilian Portuguese and French.

Results: A hierarchical cluster analysis led to four distinct clinical profiles of communication. Since only a few distinctions between nationalities were observed, the results suggest that there probably is a partial universality of clinical profiles of communication impairments after a right brain damage.

Conclusions: This study proposes a preliminary taxonomy of communication disorders among right-brain-damaged individuals with cross-cultural implications. The exploration of associated stroke sites and neuropsychological concomitant deficits would contribute to the eventual development of a more accurate clinical intervention.
