This research aims to analyze how impaired object naming relates to repetition and comprehension impairments in stroke survivors with aphasia.
Quantitative analysis of 382 stroke survivors with varying degrees of aphasia severity.
Assessment of anomia's incidence, positive predictive value, and sensitivity in relation to repetition and comprehension.
Comparison of object naming, word repetition, sentence repetition, word comprehension, and sentence comprehension.
66% incidence, 90% positive predictive value, and 63% sensitivity of anomia across the sample.
Severely aphasic participants showed 93% incidence, 100% positive predictive value, and 93% sensitivity.
Word comprehension had notably lower incidence and sensitivity compared to other tasks.
