Speech disturbances in MS typically result from mechanical disturbances of word formation result, medically known as “dysarthria.” Damage to the nerves and reduced nerve impulses can weaken the muscles of the lower face, lips, tongue, and throat, causing dysarthria.
Slurring and slowness of speech, with altered pronunciation, characterize dysarthria. Speech pathologists (also known as speech-language therapists) can teach techniques to help slow speech so that it is more understandable, as well as teach exercises to help strengthen muscles.
