Document Summary
Dysarthria is speech disorders caused by problems in the central or peripheral nervous system pathways which cause muscle dysfunction, weakness, incoordination or paralysis. Congenital dysarthria is in children who have speech problems because their muscles are weak or paralyzed. Childhood apraxia of speech (cas) is a controversial disorder. Children demonstrate severe speech disorders with words dominated by simple syllables, vowel errors and sounds that develop early (m, p, b). Children with cas do not have signi cant sensory loss, structural abnormalities or emotional disorders so neurological and generic facts have been proposed as the cause of the disorder. Most likely, the neurological disorders are the result of maldevelopment of areas of the brain that program movement sequences. Acquired apraxia of speech (aos) is a disorder in the planning and programming of speech movements due to left frontal lobe brain damage. It is characterized by slow rate, prolonged constants and vowels, pauses between words and even stress on syllables.
