Definition: “A general term applied when weakness or incoordination of the speech muscles prevents clear pronunciation of words. The voice sounds slurred or weak. It may be due to damage affecting the centers 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 and motor neuron disease”. In the clinical summaries of the NBB, this was often described as part of the neurological examination. We scored it as a separate parameter, and not as part of ‘loss of coordination’ (which could also be a choice).
