Incidence: dependent on what"s causing the problems (148,000 diagnoses of motor speech disorders: prevalence: 51% of acquired communication disorders. Stroke, tbi, anoxia, cerebral palsy: progressive neurological disorders. Parkinson"s, als, huntington"s disease, ms: msds are called either developmental and acquired. Apraxia of speech: motor planning/programming disorder. Difficulty grouping and sequencing the correct muscles. Can be both acquired or development: looks like: Grouping of articulators: often caused by. Physiological deficit and abnormal movement of muscles. Can be both acquired or developmental: looks like. Slow, slurred, quiet, or uneven speech: often caused by progressive disease or trauma, breakdown of types of dysarthia. Bilateral damage to direct and indirect activation pathways of cns. Associated with brainstem cvas d/t location of cranial nerves.
