This research project looks at three different types of written communication that address the neuropsychiatric disabilities of autism, Attention Deficit Hyperactivity Disorder (ADHD), Obsessive-Compulsive Disorder (OCD) and Tourette Syndrome (TS) in different ways: medical articles, patient-oriented information, and narratives from a user/patient perspective. An important assumption made in the study is that the language we use when communicating about disabilities both reflects and shapes how we perceive, understand and value them. By examining how language is used, we can describe the differences and similarities between the different types of communication and find out, for example, which meanings are evoked and how language shapes these meanings, which concepts are put in focus and which are given less space and, not least, which understandings and conceptual structures are based on and maintained through language. In this way, we can investigate whether medical professionals and patients/users create and maintain common understandings and values of autism, ADHD, OCD and TS through language and whether they express similar or different experiences and priorities.
