Bilinguals and aphasia

Bilingual aphasia : Frequent form of aphasia

Necessary to consider the specificities of

bil.aphasia

Age of acquisition Proficiency level Method of acquisition Motivation

Age and method of acquisition

Related:

early bil – both lgs in natural context

Fewer deficits in both lgs

late bil – L1 natural context, L2 formal context

More impairments in L2 than L1

Lesion to explicit memory circuits

Early bil – natural context

Parallel recovery

Late bil – formal context

Successive or differential recovery

Proficiency

Essential: i about pre-morbid lg performance Pitres (1895):

recovering of lg that was most familiar

Contemporary research:

effect of therapy from spontaneous

communicative situations

Motivation

Reasons:

Social Emotional Cultural Cognitive

Normal and pathological LM and LS

Communicative situation Bil with aphasia – despite the situation =

PATHOLOGICAL LM & LS

Is there choice to lg choice?

Therapy offered in both lgs or limited to one lg? Which lg then?

The most frequently used pre-morbidly? The one least impaired? The one with more emotional attachements?

Speach-language pathologists

Need to choose one lg (LM,LS)

Treating more lgs may inhibit global speech

recovery

SLPs may favor rehabilitation of both lgs

bilingual lg system = unity in bilingual environment

Considerations for therapy planning with bil aphasia

The relative intensity of use of either lg The emotional value Bilinguals with aphasia should not be deprived by

limiting lg therapy to one lg

bil aphasia requires bilingual rehabilitation

• lg system of bil person: both lgs both should be

integrated in the therapy process

Bil therapy – not always possible

Depends upon the SLP resources

Conclusion

Therapy choice made on the basis of:

The possible impact of lesion location Proficiency and method of acquisition

Therapeutic goal

To reduce the communication handicap To attain the highest possible level of functional

communication

Criticism

+/- Many questions without an answer

+ Suggestions for future studies

• Hypothesis should be tested/ should be explored

Very few research studies
