The following study examined whether similarities in motor speech deficits in Parkinson?s disease and in developmental stuttering could be observed. Furthermore, intelligibility was examined. Assessments of 16 people with Parkinson?s disease, 35 people with developmental stuttering and 49 matched controls were performed with the tests Dysartribedömningen and the Swedish Test of Intelligibility. The intelligibility of people with Parkinson?s disease was judged lower than the controls?. The results of Dysartribedömningen showed that the group with Parkinson?s disease and the group with developmental stuttering had significantly more deviant results than controls on tasks that assessed tongue extension, repeating /ka/ rapidly, pausing/phrasing and to mark stress. The results might indicate that motor speech disorders in Parkinson?s disease and developmental stuttering respectively are caused by dysfunction in partly the same brain structures. Mapping of the etiology of these motor speech disorders is of importance for treatment and preventive measures.
