Dysarthria is a speech disorder that is due to a weakness or incoordination of the speech muscles. Speech is slow. weak. imprecise or uncoordinated. In the aged population, dysarthria can be caused by stroke, degenerative disease, infections, brain tumours, and toxins. Depending on the extent and location of damage to the nervous system, a person with dysarthria may experience abnormal voice production, reduced intellegible speech, slow or rapid rate of speech, and chewing or swallowing difficulties. Treatment depends on the cause, type, and severity of the symptoms. Speech therapy goals may include direct and indirect therapy, medical or surgical treatment, environmental control, and AAC. A interdisciplinary team approach and other treatment strategies were discussed in order to develop a intervention program for the older disarthric patients in Korea.
