dysarthria

Dysarthria refers to speech problems that are caused by the muscles involved with speaking or the nerves controlling them. Both muscle weakness and incoordination can give rise to dysarthria. Speech problems that result from cognitive dysfunction are not dysarthria.

Dysarthria is a feature of many neurological diseases including cerebral palsy, stroke, traumatic brain injury, Parkinsonís disease, Amyotrophic Lateral Sclerosis (ALS) and multiple sclerosis.

Dysarthria is a relatively common symptom of multiple sclerosis and can take many forms. Episodic paroxysmal dysarthria, which is where the dysarthria lasts for up to a minute or so and recurs several times a day, is particulary common in MS.
