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.
Motor speech disorders are a class of speech disorders that disturb the body's natural ability to speak due to neurologic impairments. These neurologic impairments make it difficult for individuals with motor speech disorders to plan, program, control, coordinate, and execute speech productions. [ 1 ]
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 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.
Dysarthria is a weakness or paralysis of speech muscles caused by damage to the nerves or brain. Dysarthria is often caused by strokes, Parkinson's disease, [9] ALS, head or neck injuries, surgical accident, or cerebral palsy. Aphasia; Dysprosody is an extremely rare neurological speech disorder. It is characterized by alterations in intensity ...
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 ...
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.
Motor aprosodia is characterised by the physical inability of a patient to produce or imitate emotional indicators, with vocal inflection (volume and pitch changes) and facial gesturing being the most frequently impaired functions and with damage to the motor area of the brain being the most frequent cause of impairment. Persons exhibiting only ...
