Speech difficulties have been estimated to affect between one-third and one-half of all MS patients at some point. When there is damage to the nerves that stimulate the muscles, they may not work as quickly or precisely, resulting in motor speech disorders, the most common of which in MS are known as “dysarthrias.” These can cause words to slur, slow, be distorted, or become altered in tone.

      The most important intervention is treatment by a speech and language pathologist (SLP), who is trained to provide an accurate diagnosis and exercises. Even if the problem cannot be completely reversed, perhaps the effects can be minimized.

     Complementary natural approaches include those discussed for the disease as a whole, including diet, supplements, and physical treatments such as acupuncture and massage. Additionally, it can help to avoid dry mouth (“xerostomia”), which can worsen speech; xerostomia is covered more in-depth in the section on swallowing difficulties.
