Aprosodias

From Wikipedia, the free encyclopedia

Aprosodias are defined as acquired or developmental conditions marked by an impaired ability to comprehend or generate the emotion conveyed in spoken language.

[edit] Symptoms

Aprosodias have several subtypes:

• 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”

[edit] 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 syndroms due to dominant hemisphere damage.
