What is the most common type of dysarthria?

A lesser variant of spastic dysarthria, called unilateral upper motor neuron dysarthria, is a similar speech pattern but usually less severe, associated with a unilateral upper motor neuron lesion such as in stroke. This may be the most common type of dysarthria encountered by neurologists.

Drug-induced cerebellar syndrome can be caused by a number of drugs, including phenytoin, lithium, carbamazepine, certain chemotherapeutic agents, and aminoglycoside antibiotics. In addition to loss of coordination, some patients may experience dysarthria and nystagmus.

Which cranial nerve damage causes dysarthria?

The nuclei of cranial nerves IX and X receive bilateral input from the cortex, and unilateral lesions are often asymptomatic. Bilateral lesions of the corticobulbar tracts result in pseudobulbar palsy. Symptoms include slow, dysarthric speech and variable dysphagia, while pharyngeal and palatal reflexes remain intact.

Is dysarthria a neurological disorder?

Dysarthria is a motor speech disorder resulting from neurological injury of the motor component of the motor–speech system and is characterized by poor articulation of phonemes.

Does speech apraxia go away?

CAS is sometimes called verbal dyspraxia or developmental apraxia. Even though the word “developmental” is used, CAS is not a problem that children outgrow. A child with CAS will not learn speech sounds in typical order and will not make progress without treatment.
