An aprosodia is an acquired or developmental condition marked by an impaired ability to comprehend or generate the emotion conveyed in spoken language.

Symptoms

Aprosodias are of several types:

  • Motor aprosodia
  • Sensory aprosodia
  • Global aprosodia
  • Transcortical motor aprosodia
  • Transcortical sensory aprosodia
  • Mixed transcortical aprosodia
  • Expressive aprosodia – Disruption in pitch, loudness, rate, or rhythm that convey a speaker’s emotional intent. It can have devastating effects on communication and personal relationship. It is less awareness than for aphasia. Partner or family may think they have become “uncaring”

Proposed mechanisms

Aprosodias are caused by impairment of non-dominant hemisphere, manifested with inability of affective expression and comprehension. Its anatomical location is homologous to aphasic syndromes due to dominant hemisphere damage.
