Aprosodia Vs. Dysprosody
Brain imaging studies related to speech functions have yielded insights into the subtle difference between aprosodia and dysprosody. The major differences in these result from functions which are characterized as belonging mainly to the left or right hemisphere. Several of the functions have been described as dominant and lateralized functions of the corresponding hemispheres, while some have been found to arise from communication between the two hemispheres. While the ability to express or be receptive to affective prosody is similar in dysprosody and aprosodia, a significant difference in the characterization of them is dominant vs. non-dominant hemispherical damage.
