dysarthria /disär″thrē·ə/ [Gk, dys + arthroun, to articulate] , difficult, poorly articulated speech, resulting from interference in the control and execution over the muscles of speech, usually caused by damage to a central or peripheral motor nerve. ▪ OBSERVATIONS: There are many different types, depending on the location of the lesion. A universal finding is difficulty with the articulation of consonants. Intelligibility varies greatly, depending on the extent of neurological damage. Hypernasality is frequently present. ▪ INTERVENTIONS: Treatment will vary depending on type; strengthening the oral musculature and improving breathing patterns are often required. A speech-language pathologist will conduct an evaluation and work with the individual patient to improve communication abilities and establish treatment goals. ▪ PATIENT CARE CONSIDERATIONS: It is important for persons with dysarthria, their families and significant others, and the health care team to work together to establish good communication patterns.
