ABSTRACT
The communicative coordination of actions by and with people diagnosed with dementia is depicted in the literature as problematic to scarcely possible, especially when the neurodegenerative changes in the brain are advanced. This is mainly because the ability of these people to communicate is in doubt. That is, it is questionable whether, how, and when communication still takes place at all. Therefore, the communicative coordination of actions by and with people diagnosed with dementia is a borderline case, which is of particular interest for communicative constructivism. In the chapter, I will discuss, theoretically, how communicative action coordination with a person with dementia takes place in practice, even when the competence to express oneself verbally has largely failed. At the same time, I will consider, theoretically, how much subject must remain to speak of communicative action coordination.
