Dysarthria is a speech problem caused by muscle weakness in the face, lips, tongue, and throat. The breathing muscles are also weak. It is caused by brain damage. This may be present at birth (congenital) because of disorders like cerebral palsy. Or it may be due to a stroke or other types of brain injury. A person who has dysarthria knows which words to use. But they may not be able to make the right sounds. This disorder may also cause trouble swallowing or chewing.
