Communication profiles and executive impairments following right-hemisphere stroke: a crosscultural perspective / Perrine Ferré
Communication profiles and executive impairments following right-hemisphere stroke: a crosscultural perspective / Perrine Ferré. In "Perspectives neuropsycholinguistiques sur l'aphasie - NeuroPsychoLinguistic Perspectives on Aphasia", colloque international organisé par l'Unité de Recherche Interdisciplinaire Octogone de l'Université Toulouse II-Le Mirail (France). Toulouse, 21-23 juin 2012.
It is now accepted among the
scientific and clinical community that a right-hemisphere-stroke may
lead to communication disorders. Former studies estimate that at
least 50% of right hemisphere damaged individuals have prosodic,
discourse, pragmatics and/or lexico-semantic disorders. These aspects
of communication have been described in isolation in the literature,
but only a few studies have been devoted to the fact that they might
co-exist in a same individual. Even fewer studies have been based on
a crosscultural perspective. Executive impairments and other
cognitive processes have been suspected to underlie communication
deficits, suggesting that communication deficits are not
language-specific, but no study at large scale is available to
confirm this hypothesis.
Like the portraits of aphasia
associated with left brain injury, describing patterns of
communication following a right brain damage will help proper
identification and clinical intervention in speech and language
therapy. This research aimed at classifying communication profiles
among right-brain-damaged adults with an intercultural perspective
and with regards to other cognitive processes.
The sample is made up of 154
right-brain-damaged individuals from four nationalities (Canadians,
Brazilians, Italians and Argentineans). They were assessed using 13
language tasks from the Protocol MEC and a neuropsychological battery
addressing executive processing and attention.
A hierarchical cluster analysis
revealed four distinct clinical profiles of communication: 1-
extensive impairments in all components; 2-mixed impairments of
semantic, prosodic and discursive fields; 3-exclusive conversation
impairment and 4- mild or no impairment.
Since only few distinctions between
nationalities were to be observed, the results suggest that there
probably is a universality of clinical profiles after a right brain
damage. Exploration of executive impairment indicates that deficits
in inhibition, cognitive flexibility and attention may
exacerbate the severity and extent of deficits in all
components of communication. Nonetheless, there is no linear
association between profiles of communication and executive
impairments. Furthermore, clear dissociations at the
individual level are observable.
This study proposes a specific
taxonomy of communication disorders among right-brain-damaged
individuals in a crosscultural and cognitive perspective. It might
contribute to a better detection of communication disorders and to
the development of a more accurate clinical intervention for adults
suffering from consequences of a right hemisphere stroke.
