What is already known on this subject Sentence comprehension deficits in aphasia vary by severity and type, but prior studies have typically examined these factors separately and have rarely included individuals with latent aphasia who fall above diagnostic thresholds. As a result, it remains unclear how sentence comprehension varies across the full spectrum of aphasia. What this study adds to existing knowledge This study systematically examined how sentence comprehension accuracy and response times vary with both aphasia type and severity, across canonical and non-canonical syntactic structures. Findings demonstrate that comprehension deficits are more widespread than previously recognized, extending even to individuals with latent aphasia. What are the potential or actual clinical implications of this work? The results underscore the need for assessment tools that incorporate syntactically complex sentences to detect subtle comprehension deficits that may not be captured by standard tests. Tailoring intervention to an individual's syntactic comprehension profile may enhance treatment outcomes.
