Aprosody

  • typically caused by dysfunction in areas of the non-dominant hemisphere that structurally mirror Broca's and Wernicke's areas
    • lesions to the temporal cortex of the right hemisphere result in difficulties understanding emotional aspects of language
    • lesions in the frontal cortex of the right hemisphere result in difficulties in producing language with emotional context

  • may be secondary to another disease, particularly if the disease produces a flattening of affect (i.e., depression or schizophrenia)

  • may present as a difficulty with social interactions

  • since generation of the emotional component of speech is dependent on generation of speech itself, damage to the left hemisphere can appear to affect prosody, but this can be tested by reducing the articulation demands to simpler words or phonemes that can be produced by the right hemisphere
