Dysarthria

Dysarthria is a kind of motor speech disorder caused by neurological injury to the central or the peripheral nervous system. Speech subsystems such as respiration, phonation, resonance, prosody, and articulation can be aected, leading to the detriments in intelligibility (how well the speaker’s speech is understood by others), audibility, naturalness, and potency of vocal communication. This kind of disorder is caused by a stroke, muscular dystrophy, brain injury, tumours, Parkinson’s disease, or Huntington’s disease, or multiple sclerosis. Some dysarthric speech characteristics [1, 2, 3] are mono pitch, harsh voice, vowel distortions, strained-strangled vocal quality. Due to these characteristics, the pronunciation often suers from the following limitations: the rate of the…

As I stroll along the beach I can feel the smooth, damp sand beneath my feet. I am taken in by the soothing atmosphere that encircles me. I close my eyes, letting myself absorb the warm rays of the sun. The glowing horizon slowly fades as it descends into the waves. I am comforted by the sounds of the ocean; the rhythmic pounding of the endless sea. I look into the cloudless cerulean blue sky and see the perfection of life. As I stare into the horizon and watch every wave crash, I am reminded of…

DYSARTHRIA WHAT IS DYSARTHRIA? Speech production is a complex process involving the co-ordinated contraction of a large number of muscles controlled by the nerve impulses originating in the motor areas of cerebral cortex. The organs that are involved in speech production are the lips, the tongue, the vocal folds and the diaphragm. When these organs don’t function efficiently, the speech tends to be unclear. One such condition which results owing to the malfunctioning of the speech organs is…

Dysarthria is a collective term used to describe a group of motor speech disorders. (17) It is caused by the underlying neurological deficits that impact the muscular control and execution of movement required for speech production. (18) Dysarthria is a common symptom of many neurological disorders, and the features of the speech dysfunction are distinctive. (17) Classic dysarthric presentations are characterised by a disturbance in the subsystems of speech, namely respiration, phonation,…

Susan’s main areas of difficulty involve motor speech, which affects her intelligibility. Particularly relating to the larynx, use of the tongue in speech and coordination of the lips and palate. This indicates that Susan is likely experiencing mixed spastic-ataxic dysarthria due to lesions on the upper motor neurone pathway (Wilkinson and Lennox 2005) in the corticobulbar tract which innervates the cranial nerves and the cerebellum (Bethoux et al 2013). Lesions on the upper motor neurone…

Assessment of Quality of Life in Persons with Parkinson’s Disease Dysarthria, according to Darley et al. (1969), is characterized by all speech disorders related to disturbances of muscular control of the speech organs, whose origin could be a central or peripheral nervous system. Based on site of lesion and presenting symptoms, dysarthria is classified into different types. For examples Upper motor neuron system (UMN) lesions leads to spastic dysarthria, lower motor neuron (LMN) lesions lead…

Dysarthria is a speech disorder caused by a stoke, cerebrum damage, tumors, or Parkinson's disease. Dysarthria damages movements in muscles used for speech production. These muscles incorporate the tongue, vocal folds, lips and diaphragm. Dysarthria is weakened in communication due to shortcoming, loss of motion and incoordination of speech. It influences your pitch, loudness, voice quality, prosody, respiration and articulation. There are numerous sorts of dysarthria's, which are…

Ataxic dysarthria is a motor speech disorder associated with some kind of damage (degenerative, vascular, demyelinating, tumor, traumatic, toxic/metabolic/endocrine, and other possible causes) to the cerebellar control circuit, which consists of the cerebellum and its connections. It may cause problems in the articulatory, respiratory, phonatory, and resonatory components of speech. However, the disorder is most evident through the articulatory and prosodic components of speech. Individuals with…

Steven has a speech disability called dysarthria. Dysarthria is an impediment where the muscles in the face, mouth and respiratory system become weak, move slowly or not at all, as a result of stroke or other brain injury (Terrific Talkers). Steven knows what he wants, but the cashier isn’t being patient and now they're both frustrated. He goes home, Tesco bag empty with tears rolling down his cheeks. You see, when a person is illiterate in the language that they are engulfed by, surrounded by…

Hypokinetic dysarthria is a motor speech disorder where it is linked with the basal ganglia control circuit pathology. The disorder can manifest in the patient’s voice, articulation, respiration, and prosody. It can cause harsh-hoarse voice quality, reduce range of motion (ROM), reduced vocal cords, reduced phonation time, reduced and monoloudness of pitch, and/or low rate with intermittent rapid bursts. The disorder is associated with the basal ganglia control circuit pathology which consists…
