What causes dysarthria?
Muscles used for speech are controlled by the brain and nervous system and can develop from brain damage either before or during birth, such as with cerebral palsy or later in life, such as damage caused by a stroke, severe head injury or brain tumour, or a progressive condition such as Parkinson’s disease or motor neurone disease.
