Dysarthria is a motor speech disorder that results from a neurological injury. Neurodegenerative conditions like Parkinson's disease, amyotrophic lateral sclerosis, and progressive supranuclear palsy frequently transpire in association with dysarthria. [6] Some stem from central damage, while other stem from peripheral nerve damage.
Dysarthria is the reduced ability to motor plan volitional movements needed for speech production as the result of weakness/paresis and/or paralysis of the musculature of the oral mechanism needed for respiration, phonation, resonance, articulation, and/or prosody.
Dysdiadochokinesia is also seen in Friedreich's ataxia and multiple sclerosis, as a cerebellar symptom (including ataxia, intention tremor and dysarthria). It is also a feature of ataxic dysarthria. Dysdiadochokinesia often presents in motor speech disorders , therefore testing for dysdiadochokinesia can be used for a differential diagnosis.
Dysarthria is a speech sound disorder resulting from neurological injury of the motor component of the motor–speech system [1] and is characterized by poor articulation of phonemes. [2] It is a condition in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words.
Principles of motor learning theory and intense speech-motor practice seem to be the most effective; Non-speech oral motor therapy is not necessary or sufficient; A multi-sensory approach to therapy may be beneficial: [25] using sign language, pictures, tactile cues, visual prompts, and augmentative and alternative communication (AAC) can be ...
Fine motor planning, control and coordination are often affected. [117] Dysarthria, a speech disorder resulting from neurological damage to the motor-speech system, occurs in an estimated 31% to 88% of those with cerebral palsy. Such individuals may require AAC support for communication.
Developmental coordination disorder (DCD), also known as developmental motor coordination disorder, developmental dyspraxia, or simply dyspraxia (from Ancient Greek praxis 'activity'), is a neurodevelopmental disorder [1] characterized by impaired coordination of physical movements as a result of brain messages not being accurately transmitted to the body.
Dysarthria is a motor speech disorder caused by damage to the central and/or peripheral nervous system, and it is related to degenerative neurological diseases, such as Parkinson's disease, cerebrovascular accident (CVA), and traumatic brain injury (TBI). [13]
