Multiple Sclerosis is not known to cause significant symptoms in hearing (although there can always be the occasional exception), even if a test called an
‘auditory evoked response’ reveals some damage to the relevant nervous pathways. Very, very occasionally some hearing loss may occur temporarily as a result of the MS but, if your hearing loss is gradual or persistent, it needs investigating for other causes. Sometimes in order to diagnose and help problems with your speech, an audiological assessment may be carried out; however, any problems – as we have noted – are almost certainly not caused by the Multiple Sclerosis itself.
