Neurological Disorders Affecting Voice

Many neurological disorders that affect voice may also affect speech. This relationship is applicable in more cases involving central nervous system disorders than it is to peripheral nervous system disorders. However, even with peripheral disorders, speech and voice may be affected, as with Myasthenia Gravis (7150). Whenever a neurologic condition is suspected, not only voice but also speech should be examined carefully.
