Difficulties with speech and language are the first and most notable symptoms of primary progressive aphasia (PPA). While there is evidence that demonstrates positive effects of speech-language treatment for individuals with PPA who only speak one language (monolinguals), there is a significant need for investigating the effects of treatment that is optimized for bilingual speakers with PPA. This stage 2 efficacy clinical trial seeks to establish the effects of culturally and linguistically tailored speech-language interventions administered to bilingual individuals with PPA.
The overall aim of the intervention component of this study is to establish the relationships between the bilingual experience (e.g., how often each language is used, how "strong" each language is) and treatment response of bilinguals with PPA. Specifically, the investigators will evaluate the benefits of tailored speech-language intervention administered in both languages to bilingual individuals with PPA (60 individuals will be recruited). The investigators will conduct an assessment before treatment, after treatment and at two follow-ups (6 and 12-months post-treatment) in both languages. When possible, a structural scan of the brain (magnetic resonance image) will be collected before treatment in order to identify if brain regions implicated in bilingualism are associated with response to treatment. In addition to the intervention described herein, 30 bilingual individuals with PPA will be recruited to complete behavioral cognitive-linguistic testing and will not receive intervention. Results will provide important knowledge about the neural mechanisms of language re-learning and will address how specific characteristics of bilingualism influence cognitive reserve and linguistic resilience in PPA.

| Lexical Retrieval Training | Experimental | Naming intervention for individuals with logopenic or semantic variant PPA. |

| Video Implemented Script Training for Aphasia | Experimental | Script training intervention for individuals with nonfluent/agrammatic PPA. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Video-Implemented Script Training for Aphasia (VISTA) | Behavioral | Participants with nonfluent/agrammatic variant primary progressive aphasia (PPA) or a predominantly nonfluent profile work on producing personally relevant scripts of 4-6 sentences in length. Length and complexity of scripts are individually tailored. The participant completes two (one hour each) teletherapy sessions per week with a clinician targeting clear and accurate script production, script memorization, and conversational usage of scripts. The participant completes 30 minutes of independent, computer-based practice 5-7 times per week, during which they speak in unison with a video/audio model of a healthy speaker clearly articulating the scripts. |
| Measure | Description | Time Frame |
|---|---|---|
| Percent correct intelligible words from trained/untrained scripts | Percent of intelligible, scripted words for trained scripts and untrained scripts | Pre-phase 1, post-phase1/pre-phase 2 (4.5 weeks from treatment onset), post-phase 2 (9 weeks from treatment onset), 6 months and 1 year post-treatment |
| Percent correct spoken naming of trained/untrained nouns | Percent of correctly named trained pictured items and untrained pictured items | Pre-phase 1, post-phase1/pre-phase 2 (4.5 weeks from treatment onset), post-phase 2 (9 weeks from treatment onset), 6 months and 1 year post-treatment |
| Measure | Description | Time Frame |
|---|---|---|
| Aphasia Impact Questionnaire (AIQ) | Patient reported outcome measure for use with people with aphasia comprising three sections: activities, participation and emotional state/wellbeing. Uses a 5 point pictorial rating scale. The minimum score is 0 (best) and the maximum is 4 (worst). | Pre-phase 1, Post-phase 2 (9 weeks from treatment onset) |
| Measure | Description | Time Frame |
|---|---|---|
| Post-treatment Communication Survey | Survey characterizing perceived response to treatment. Scale scale options are as follows: "a lot worse", "worse", "somewhat worse", "unchanged", "somewhat better", "better", and "a lot better." There are seven levels with "a lot worse" being the lowest rating and "a lot better" being the best rating. | Post-treatment (approximately 6-12 weeks after treatment onset) |

| Lexical Retrieval Training (LRT) | Behavioral | Participants with logopenic variant PPA, participants with semantic variant PPA, and participants with a predominantly anomic profile will work on producing spoken and written names of personally relevant target items using a self-cueing hierarchy. Treatment focuses on the use of strategies that capitalize on spared cognitive-linguistic abilities to support word retrieval. The participant completes two (one hour each) teletherapy sessions per week with a clinician plus 30 minutes of additional independent, computer-based practice exercises 5-7 times per week. |
