Compensatory and Restorative Application of AAC in Chronic, Severe Aphasia
Alternative and augmentative communication (AAC) strategies in persons with aphasia (PWA) require careful consideration. Cognitive and linguistic strengths and limitations directly influence device and field complexity as well as language content and layout. Without a general understanding of the PWA’s phonological, semantic, syntactic, and input/output span abilities, the effectiveness of AAC for PWA can be significantly limited.
GA was a 68-year-old left-handed man status post multiple, remote, cerebrovascular accidents (CVAs), the most recent of which was 10 years ago. His medical history and the course surrounding the CVAs were limited as his care was at a different facility. However, a head computed tomography was available for review, which showed a large wedge-shaped area of infarction in the left hemisphere in the area of the middle cerebral artery (MCA) distribution extending from the frontal to the parietal lobe. Per report, he received speech-language therapy immediately following one of his strokes, but he had not received services within the past 5 years.
