The problems in MS depend on the
area of nervous system most affected. In your wife’s case, the
speech area appears to have been affected. However, the good news is that the problems persist only during the relapses or when the person is extremely tired.
Speech problems may include slurring, long pauses between words, nasal speech, tremor in voice etc. You could ask the hospital to send across a speech therapist. This will help improve her speech even while the inflammation is there.
