What Causes the Speech and Swallowing Problems of Multiple Sclerosis?
Like other symptoms of multiple sclerosis, if you’re experiencing swallowing or speech difficulties, it’s because you have an area of damaged nerves that normally aid in performing these tasks. Locating the damaged areas responsible for the speech problem is often difficult. Many areas in the brain, especially the brainstem, control speech patterns. Thus, lesions — another name for damaged areas — in different parts of the brain can cause several types of changes in normal speech patterns. They range from mild difficulties to severe problems that make it difficult to speak and be understood.
