Speech and communication disorders in adults


Project group leader

Ellika Schalling

Speech and/or voice may be affected in individuals with chronic neurological disease or injury. This is for example common in individuals affected by Parkinson’s disease, Multiple Sclerosis, stroke, hereditary cerebellar ataxias or cervical spinal cord injury. We study symptoms and prevalence of speech and voice disorders in neurological disease/injury in different projects. In one project gender differences in different ages in young women and men who stutter is also studied. The group is also devoted to development and improvement of assessment methods related to speech and voice function including the impact of changes of communication on communicative participation. We also work with development and assessment of effects of different speech and language pathology interventions for individuals with chronic neurologic diseases or injuries.
