Efficacy of Communication Bridge‐2 for primary progressive aphasia: A randomized controlled trial of communication intervention
Abstract
Primary progressive aphasia (PPA), a language‐based neurodegenerative dementia, negatively impacts communication and quality of life. Previous non‐pharmacologic interventions show promise but lack efficacy trials. Here, outcomes are provided from Communication Bridge‐2 (CB2), a speech‐language randomized controlled trial (RCT) for PPA.
