How is vestibular neuronitis diagnosed?Vestibular neuronitis is usually diagnosed from your symptoms of sudden vertigo, nausea, and vomiting with no hearing loss.
It is common for people to use the terms vertigo, dizziness, and lightheadedness interchangeably. However, they are not the same, and it is important to be able to tell the doctor which one you are experiencing.
Your doctor will take your medical history and perform a physical exam to learn the cause of vertigo. The physical exam usually includes the Dix-Hallpike test.
