Vertigo is a symptom specifically related to dysfunction of the vestibular system in the ears. True rotary vertigo is the name given to dizziness whereby the sufferer feels as though the room or they themselves are rotating.
When balance (vestibular) function suddenly drops in one ear, the brain becomes confused by the change, resulting in a sensation of vertigo. Very often the brain can adapt to this change and the symptoms may resolve – but it may take many months and much training. If the system fails to fully compensate, then balance difficulties may persist.
Dizziness is an uncommon symptom of an acoustic neuroma because tumour growth is typically very slow, allowing plenty of time for the body’s compensatory mechanisms to take effect. Balance rehabilitation plays an important part in the recovery process and you should enquire about this through your acoustic neuroma team.
