The logopenic variant of primary progressive aphasia is most associated with which feature?

The feature being tested is the characteristic language profile of the logopenic variant of primary progressive aphasia. This form is driven by a disruption of phonological working memory, which makes repetition—especially of longer phrases and sentences—impaired and often accompanied by phonological errors. At the same time, single-word comprehension remains relatively preserved early in the course because semantic knowledge is largely intact. Speech tends to be fluent but with pauses and word-finding difficulties, rather than the effortful, halting, agrammatic speech seen in nonfluent variants or the severe naming and semantic deficits seen in semantic variants. The combination of impaired repetition with phonological mistakes and preserved single-word understanding is the hallmark pattern of this variant, setting it apart from the others where the primary deficits center on production mechanics, semantics, or broader perceptual impairments.
