Study Overview
Brief Summary
Every year thousands of persons suffer from brain damage resulting in anomia, that is, word finding difficulties affecting their ability to talk to other people. Anomia may be a result of stroke or of progressive neurological diseases such as Parkinson's disease or multiple sclerosis (MS). Word retrieval is dependent on a complex system of different neural networks and to name objects and activities can be affected to different degrees. The present project explores different aspects of naming ability in altogether 90 persons that has anomia related to stroke or to Parkinson's disease or MS. Furthermore, the communicative strategies and resources used by conversation partners in everyday conversational interaction and in care situations, affected by anomia are studied. Finally, the project includes a study of the effectiveness of a word finding training program based on stimulation of semantic and phonological networks in the brain, involved in the production of words. There is a lack of research on effects on communication from anomia in Parkinson's disease and MS and there is no research on anomia that investigates both object and action naming using a material adapted to the Swedish language. In the project quantitative and qualitative methods are used to explore and describe how persons with different neurogenic communication disorders can use different resources and communicative strategies to express themselves.
Detailed Description
Project out line
The main project consists of:
- A descriptive study of the occurrence and type of naming difficulties in people with stroke, Parkinson's disease or Multiple sclerosis (MS) where quantitative data is compared at group level, (study 1).
- A descriptive study in which word search strategies are investigated with both quantitative and qualitative methods (study 2).
- A series of three intervention studies examining the effect of treatment of anomia (studies 3-5).
Study 1: The relation between type of injury and ability to name objects and actions and complex semantic-pragmatic word fluency
Participants The project includes a total of 90 people with anomia: 50 subjects with anomia after stroke, 20 individuals with Parkinson's disease and 20 individuals with MS are recruited are recruited through patient associations and health care facilities in Västra Götaland and included consecutively.

Outcomes
Primary Outcomes
Naming ability in the Object & Action Naming Battery
Time Frame: At baseline before start of intervention and after 21 days, at completion the intervention program
A measure of change in ability to name forty pictures consisting of simple black and white drawings. There is a 20-second time limit for response for each picture. Number of correct objects and activities will be calculated separately (range 0-20) as well as summarized (range 0-40)
Secondary Outcomes
- Naming of 20 individually chosen training words(At baseline before start of intervention and after 21 days, at completion the intervention program)
- Sustained change in naming of 20 individually chosen training words(At a twelve week follow up after the completion of the intervention)
- The Communication Outcome After Stroke (COAST) scale(At baseline before start of intervention and after 21 days, at completion the intervention program)
- The Stroke Aphasia Quality of Life (SAQOL-39)(At baseline before start of intervention and after 21 days, at completion the intervention program)
- Sustained change in the Stroke Aphasia Quality of Life (SAQOL-39)(At a follow up twelve weeks after completion of intervention)
- Sustained change in naming ability in the Object & Action Naming Battery(At a twelve week follow up after the completion of the intervention)
- Sustained change in the Communication Outcome After Stroke (COAST) scale(At a twelve week follow up after the completion of the intervention)
- Retelling of events in video clips(At baseline before start of intervention and after 21 days, at completion the intervention program)
- Sustained change in retelling of events in video clips(At a 12 week follow up after the completion of the intervention)
- The Communicative Participation Item Bank (CPIB)(At baseline before start of intervention and after 21 days, at completion the intervention program)
- Sustained change in the Communicative Participation Item Bank (CPIB)(At a 12 week follow up after the completion of the intervention)
