Augmentative and Alternative Communication (AAC) for adults with severe aphasia: where we stand and how we can go further.

PURPOSE: To review literature specific to the use of AAC with adults who have severe aphasia.

METHOD: The authors reviewed studies involving AAC interventions for adults with severe aphasia.

RESULTS

Published data support the use of aided and unaided AAC with adults with severe aphasia in controlled treatment contexts. Reported gains in communication typically have not generalized to everyday settings.

CONCLUSIONS

The application of AAC with persons with severe aphasia must address factors potentially limiting treatment success outside of training environments.
