Wernicke's aphasia reflects a combination of acoustic-phonological and semantic control deficits: A case-series comparison of Wernicke's aphasia, semantic dementia and semantic aphasia

► Wernicke's aphasia (WA) is the classic neurological model of comprehension impairment. ► WA has never been directly compared to semantic dementia and semantic aphasia. ► WA comprehension impairment reflects dual deficits in acoustic-phonological analysis and semantic cognition.
