Official title

Optimizing and Understanding Semantic Feature Analysis Treatment for Aphasia: A Randomized Controlled Comparative Effectiveness Trial

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This randomized controlled comparative effectiveness study examines manipulation of a key component of an established and efficacious treatment for naming impairments in aphasia, along with cognitive and brain correlates of treatment success. Study participants will be randomly assigned to one of two treatment conditions comparing two different versions of Semantic Feature Analysis treatment. Their performance on standardized and study-specific measures will be used to determine which version of the treatment provides superior outcomes, and measures of automatic language processing and functional brain imaging will also be used to identify the underlying neurocognitive mechanisms associated with positive treatment response.
