Also known as pseudo-foreign accent disorder, it is caused by damage or injury to the brain that causes the patient to be unable to control the way in which they speak, but does not effect the use or comprehension of language. . Diagnostic confirmation of aprosodia using brain scanning techniques is a relatively recent occurrence, at least with respect to quantitative specificity. Affective aprosodia from a medial frontal stroke. This may also be referred to as psuedo-foreign dialect because the individual affected is not actually a foreign English speaker, despite the way in which he or she is now speaking.

Cerebellar damage produces disorders in fine movement, equilibrium, posture, anatomically, the human cerebellum has the appearance of a separate structure attached to the bottom of the brain, tucked underneath the cerebral hemispheres. The disorder alters the way a person speaks - affecting the frequency, rhythm, and melody of the voice in such a way that it sounds like the person is speaking with a foreign accent, even though the vocabulary they use when they speak is the same. Evaluation of these two parts can determine if the patient has linguistic dysprosody. The largest study of treatments for aprosodia consisted of only fourteen individuals, resulting in sample sizes too small to report statistical significance when comparing one treatment to another.

On the other hand, pitch perception, such as singing and linguistics related to emotion, are believed to be organized in the right hemisphere. The first step in therapy is practice drills which consist of repeating phrases using different prosodic contours, such as pitch, timing, and intonation. Some disabilities start at birth - congenital disabilities. Experienced speech therapists and pathologists may well have further information and advice about the disorder, and organisations dedicated to supporting those with speech disorders and difficulties may be able to provide further information or get in touch with a specialist who can do so. There have been more recent occurrences of people who have developed accents after brain injuries, specifically strokes. This hypothesis, however, has also been a cause for concern as studies have shown that people with left hemispheric damage exhibit prosodic deficiencies associated with the right hemisphere as defined by the functional lateralization hypothesis and vice versa.

There has been strong evidence that dysprosody does affect the ability to express emotion, however the severity may vary depending on what part of the brain has been damaged. Studies have shown that the ability to express emotional information is dependent on motor, perceptual, and neurobehavioral functions all working together in a specific way. As brain imaging techniques are refined to allow for greater temporal and spatial resolution, it is hoped that more will be able to be learned about aprosodias at a functional anatomical level. In the comprehension section, the patient is asked to listen to sentences being said and then answer questions about how they were stated. Brain and Language, 104 1 , 51-74.

Scientists are continuing to study these patients in the hope of creating more concrete connections between areas of brain damage and prosodic abnormalities, which will hopefully someday lead to a full understanding of prosodic organization in the brain. While the individual's personality, sensory comprehension, motor skills, and intelligence all remain intact, their grammar as well as vocal emotional capacity can be affected. Dysprosody nonassociated with neurological diseases—a case report. The patient underwent surgery to correct a , which originates in the of the. Aprosodia can be considered a dominant function of the right hemisphere because strong correlation was found between deficits in affective prosody and distribution of lesions in the cortices of those with right brain damage.

Several of the functions have been described as dominant and lateralized functions of the corresponding hemispheres, while some have been found to arise from communication between the two hemispheres. It is worth noting however, that this localization occurs over a range of areas that can vary from person to person and more research is required to further define these areas.

Typically a clinician will say either syllables, words, phrases, or nonsensical sentences with certain prosodic contours, and the patient repeats them with the same prosodic contours. Speech-language pathologists use intonation training to provide patients with verbal apraxia the practice they need to relearn this important communication skill. Patients exhibiting extreme cases of aprosodia speak in a monotone fashion and are barely able or unable to distinguish changes in stress or intonation.
