Aprosodia

Aprosodie or Dysprosodie ( the lack or absence of prosody; emotional content of language) is a functional disorder of the central nervous system.

Disease

One can distinguish an expressive or executive (expression) and receptive ( perception) form of Aprosodie.

Both vascular cognitive disorders can be divided into the non-dominant hemisphere structures, assign inferolateral frontal cortex ( executive Aprosodie ) and superior temporal gyrus ( receptive Aprosodie ).

• Expressive Aprosodie

The patient, it is no longer possible to use certain language attributes, such as intonation, accent, intonation and pitch to express not purely substantive elements of the language. The language of the patient appears flattened and emotionless. The word education and syntax are - unlike the aphasia - usually not affected.

• Receptive Aprosodie

A patient can not judge whether a sentence sounds happy, sad or angry.

Cause

The cause is a localized injury to the cerebrum, usually is not the dominant language hemisphere ( in most people the right ) in the region of the frontal operculum affected. The reasons may come into question, for example, strokes or tumors.

It is still unclear how Aprosodie terms of neuronal localization in sensory Aprosodie (affects language comprehension ) and motor Aprosodie ( relates to speech production ) can be divided.

E. Ross and M. Mesulam 1979 published two case studies of dissociation of emotional experience and behavior in the wake of a right hemisphere infarction. The observed clinical constellation of a dissociation of emotional experience and behavior on a vocal level is referred to as motor Aprosodie (see Ackermann et al., 1993).
