Word-finding difficulty is typically an early and frustrating symptom in primary progressive aphasia (PPA). This thesis reports a case series of single case experimental design studies of word-finding treatment with 10 individuals with PPA. It examines treatment gains, maintenance of gains, and generalisation of gains to untreated items and a semi-structured interview. We observed a range of outcomes and adherence patterns under the same treatment protocol and describe disease and participant factors associated with these outcomes. The thesis also presents resources to assist with clinical decision-making about the suitability of lexical retrieval treatment for individuals with PPA.
