In a person with dysarthria, a nerve, brain, or muscle disorder makes it difficult to use or control the muscles of the mouth, tongue, larynx, or vocal cords, which make speech.
The muscles may be weak or completely paralyzed, or it may be difficult for the muscles to work together.
Dysarthria may be the result of brain damage due to:
Brain tumor
Dementia
Stroke
Traumatic brain injury
Dysarthria may result from damage to the nerves that supply the muscles that help you talk, or to the muscles themselves from:
Face or neck trauma
Surgery for head and neck cancer, such as partial or total removal of the tongue or voice box
Dysarthria may be caused by diseases that affect nerves and muscles (neuromuscular diseases):
Cerebral palsy
Multiple sclerosis
Muscular dystrophy
Myasthenia gravis
Parkinson's disease
Other causes may include:
Alcohol intoxication
Poorly fitting dentures
Side effects of medications that act on the central nervous system, such as narcotics, phenytoin, or carbamazepine
