A general term applied when weakness or incoordination of the speech musculature prevents clear pronunciation of words. The individual’s speech may sound as if it is slurred or weak. It may be due to damage affecting the centres in the brain which control movements of the speech muscles, or damage to the muscles themselves.

Examples of dysarthria may be found in strokes, CEREBRAL PALSY and the latter stages of PARKINSONISM, MULTIPLE SCLEROSIS (MS) and MOTOR NEURONE DISEASE (MND). Whatever the cause, a speech therapist can assess the extent of the dysarthria and suggest exercises or an alternative means of communication.
