Dys-

Speech that is characteristically slurred, slow, and difficult to produce (difficult to understand).

The person with dysarthria may also have problems controlling the pitch, loudness, rhythm, and voice qualities of their speech.

Dysarthria is a disorder caused by paralysis, weakness, or inability to coordinate the muscles of the mouth.

Dysarthria can occur as a developmental disability.

It may be a sign of a neuromuscular disorder such cerebral palsy or Parkinson disease.

Treatment of dysarthria is by intensive speech therapy with the focus on oral-motor skill development.
