Dementia is associated with an ongoing decline in language function, involving both language production and comprehension. Maintaining a conversation with persons with dementia may be challenging. In this conversation analytic case study of one individual with dementia, we investigate how the contributions of professional caregivers affect the linguistic contributions of the speaker with dementia. The data are drawn from a five-hour video corpus collected at a Swedish speaking care facility in Finland. In comparing self-directed speech and dialogue, the results show how professional caregivers can induce change in the linguistic and interactional behaviors of a person with dementia. Introducing an interactional perspective to self-directed speech and dialogue, this study provides new insights into the notion of a "good conversation" in dementia care.
