This article provides a schematic overview of the relevance of deixis in dementia from the perspective of a phenomenological psychopathology with an inter- and transdisciplinary scope. It distinguishes between verbal, corporal and medial deixis in the therapeutic field and discusses their respective importance in the most common dementia, Alzheimer's dementia: Verbal indexicalia have on the one hand a deficit-indicating function for the loss of higher cognitive skills, such as language, orientation and memory, and are relevant for dementia diagnosis and its structural interpretation. The paper argues that on the other hand a) the corporal deixis is an important communicative resource, which helps to create, navigate and maintain attentionality and intentionality by its multimodal character (mimics, gestures and voice) and b) the medial deixis (arrows, signs, markings) is an important creative resource, which supports orientation despite cognitive impairments. The paper argues for more attention to the corporal and medial dimensions of deixis in the context of dementia in particular, and psychiatry and psychopathology in general.
