ABSTRACT
Speech–language pathologists are increasingly called upon to differentially diagnose aphasia and language of dementia. Although traditional aphasia tests may give some insight into the language deficit in dementia, such an impairment is not always well understood. Yet the experienced speech-language pathologist will subjectively identify the conversational discourse of the dementia patient as somewhat unusual or incoherent in comparison to the aphasic. Few available standard aphasia batteries can identify the subtle differences between aphasia and the language of dementia often noted by the experienced clinician.
