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.
This disorder is characterized by the adult-onset triad consisting of the following symptoms: sensory ataxic neuropathy, dysarthria, and ophthalmoparesis. MRIS often reveals white matter abnormalities and bilateral thalamus lesions. Other symptoms include generalized myopathy, epilepsy, and deafness. [1] [2]
SCA 1 dysarthria may vary in severity depending on the task and is often associated with more strained, strangled or harsh sounding vocalization than that of other disorders. [2] Because of the significant variance between cases of SCA1, typical signs and symptoms may appear alongside more subtle or rare symptoms.
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.
In patients, a common symptom is letter-by-letter reading or LBL. This action is a compensatory strategy which these patients use in order to come up with a semblance of reading. [ 9 ] It is essentially looking at the consonants and vowels of the word and sounding them out as they sound.
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 ...

Spinocerebellar ataxia type 13 (SCA13) is a rare autosomal dominant disorder, which, like other types of SCA, is characterized by dysarthria, nystagmus, and ataxia of gait, stance and the limbs due to cerebellar dysfunction.
