The qualitative analysis of naturally occurring discourse in neurogenic communication disorders, specifically in dementia studies, has experienced recent burgeoning interest from wide-ranging disciplines. This multidisciplinarity has been exciting, but has added contextual confusion. This book advances the study of discourse in dementia by systematically exploring and applying different approaches to the same free conversational data sets, collected and transcribed by the authors. The applied methodologies and theories comprise a useful sourcebook for students, researchers, and practitioners alike.
