ACQUIRED APROSODIA IN CHILDREN

In adults, the affective components of language, including certain aspects of prosody and gesturing, appear to be a dominant function of the right hemisphere. The various combinations of affective processing deficits associated with focal right brain damage are called aprosodias and have functional and anatomical correlates similar to the propositional language deficits associated with aphasias secondary to focal left brain damage. Developmental affective-prosodic deficits have been reported recently in children with congenital or very early right hemisphere injury. We now report two school-aged children with acquired motor-type aprosodias following acute right focal brain injury. Their affective prosody and singing were also analyzed acoustically during the acute and recovery phases of illness. Based on these cases, we propose the term children aprosodia to describe affective-prosodic deficits that result from acquired lesions of the right hemisphere in children.
