Aprosody

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

Clinical picture

One can distinguish between an expressive or executive (expression) and a receptive (perception) form of the aposody.

Both vascular-related cognitive disorders can be assigned to the non-dominant hemisphere structures, inferolateral frontal cortex (executive aprosody) and superior temporal gyrus (receptive aprosody).

Expressive aprosody

It is no longer possible for the patient to use certain language attributes such as B. to use speech melody, accent , intonation and pitch in order not to express purely content-related elements of the language. The patient's language appears flattened and unemotional. The word formation itself and the syntax are - unlike in aphasia - usually not impaired.

Receptive aposody

A patient can no longer judge whether a sentence sounds happy, sad or angry.

root cause

The cause is circumscribed damage to the cerebrum , usually the non-language-dominant hemisphere (in most people the right hemisphere) in the area of the frontal operculum . The reasons can be B. strokes or tumors come into question.

It is still unclear to what extent aprosody can be divided into a sensory aprosody (affects language understanding) and motor aprosody (affects language production) in terms of neural localization.

E. Ross and M. Mesulam published two case studies in 1979 of the dissociation of emotional experience and behavior in the wake of a right hemispheric infarct. The observed clinical constellation of a dissociation of emotional experience and behavior at the vocal level is referred to as motor aprosody (cf. Ackermann et al. 1993).
