A PICTURE OF SPEECH DISTURBANCES IN CHILDREN WITH CEREBELLAR ATAXIA
Journal Title: Acta Neuropsychologica - Year 2015, Vol 13, Issue 4
Abstract
Background: The paper presents the logopedic problems of diagnosing children with cerebellar ataxia. Cerebellar lesions, which result inter alia in a discoordination of the muscular movements of the articulatory apparatus, are the cause of ataxic dysarthria – the type of dysarthria least described in the Polish subject literature. The etiology of acquired ataxic dysarthria points inter alia to cerebellar tumors, and neurodegenerative and metabolic diseases, while congenital dysarthria is attributed, for example, to cerebral palsy.Material/Methods: The paper presents the results of the speech-therapy examinations of three children aged 6 to 12 years with a medical diagnosis of ataxia during medical conditions causing cerebellar dysfunctions such as cerebral palsy (A), brain tumor (B), and metabolic disorders (C). The descriptive part of the diagnostic pro cedure takes into account the examinations using The Dysarthria Scale. Children’s Version devised by U. Mirecka and K. Gustaw, experimental phonological hearing tests, observations of linguistic behaviors, the assessment of the body posture in communication situations, and the assessment of the anatomical condition of the speech apparatus.Results: The following were diagnosed in the three children: Case A – moderate ataxic dysarthria, Case B – moderate ataxic dysarthria, oligophasia and dysglossia, and Case C – mild ataxic dysarthria and multiple, complex dyslalia. The paper presents the symptoms of ataxic dysarthria at the segmental and suprasegmental levels of the examined children’s utterances, both those regarded as typical and less typical.Conclusions: The conclusions emphasize that speech-therapy practice should take into account, when diagnosing children with cerebellar ataxia, the possibility of other speech pathology entities co-occurring with dysarthria and the occurrence of less typical dysarthric symptoms in children as compared with adults.
