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.
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.
The Boston Diagnostic Aphasia Examination provides a comprehensive exploration of a range of communicative abilities. Its results are used to classify patient's language profiles into one of the localization based classifications of aphasia: Broca's, Wernicke's, anomic, conduction, transcortical, transcortical motor, transcortical sensory, and global aphasia syndromes, although the test does ...
Flaccid dysarthria is a motor speech disorder resulting from damage to peripheral nervous system (cranial or spinal nerves) or lower motor neuron system. Depending on which nerves are damaged, flaccid dysarthria affects respiration, phonation, resonance, and articulation. It also causes weakness, hypotonia (low-muscle tone), and diminished ...
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 ...
Dysarthria is the lack of motor skills required to produce understandable speech. Dysarthria is strictly a motor problem, and is not related to the patient's ability to comprehend speech. Strokes that cause dysarthria typically affect areas such as the anterior opercular, medial prefrontal and premotor, and anterior cingulate regions.
Observation of his perceptual speech characteristics and Frenchay Dysarthria Assessment results suggested AB suffered from hypokinetic dysarthria with a marked palilalia. It was determined to start speech therapy with passive (metronome) and active (pacing boards) pacing techniques to reduce the number of palilalic repetitions.
Type 2 episodic ataxia (EA2) is characterized by acetazolamide-responsive attacks of ataxia with or without migraine. Patients with EA2 may also present with progressive cerebellar atrophy, nystagmus, vertigo, visual disturbances and dysarthria. These symptoms last from hours to days, in contrast with EA1, which lasts from seconds to minutes.
