What is the prognosis (outlook) for someone who has dysarthria?

The prognosis depends on what caused the dysarthria. For many of the conditions, the symptoms may last for the rest of the patient’s life. In some cases, such as after surgery, the symptoms may improve. However, for some degenerative conditions, a person may in time completely lose the ability to speak.
