Acoustic neuromas can make for some nasty unilateral peripheral vestibular symptoms as that tumor sits on the vestibulocochlear nerve (cranial nerve VIII). Depending on the size, hearing loss can also be a symptom as hearing and vestibular balance run in that same nerve. If it’s pretty big, it can compress other structures and cause other symptoms, such as the facial numbess/tingling/weakness the survivor mentions in the article.
What really is terrible is that the treatment for these is often to sever the nerve in attempting to remove the tumor. Which makes the vestibular problems worse in the short run and usually completely knocks out hearing on that side. However, by making putting the nerve in a steady state– no signals coming from it at all– vs. the unsteady state it is in with the tumor– having altered and varying signals coming through– the amazing brain can adjust the central gain, so that it is possible to regain at least some of those vestibular balance functions again by compensating with the remaining functional vestibular system.
I love studying physiology. The body is truly an amazing creation. Happy Acoustic Neuroma Awareness Week!
