Vestibular nerve inflammation, also known as vestibular neuritis, is a medical condition characterized by the inflammation and swelling of the vestibular nerve, which is responsible for relaying sensory information related to balance and spatial orientation from the inner ear to the brain.
The vestibular nerve is a component of the vestibulocochlear nerve (cranial nerve VIII) and is located within the inner ear. When this nerve becomes inflamed, it can lead to a range of symptoms such as vertigo, dizziness, loss of balance, and blurred vision. These symptoms often occur suddenly and can be disabling, causing difficulty with basic activities like walking or standing upright.
Vestibular neuritis is commonly caused by a viral infection, such as the herpes simplex virus, which can affect the vestibular nerve. Other potential causes include bacterial infections, autoimmune disorders, and certain medications. The condition predominantly affects adults and is more common in women than men.
Treatment for vestibular nerve inflammation typically involves medications to treat vertigo and dizziness symptoms, such as anti-nausea drugs and vestibular suppressants. Additionally, physical therapy exercises that aim to improve balance and reduce symptoms may also be recommended. In most cases, the inflammation subsides within a few weeks to a couple of months, and the individual gradually regains their balance and normal functioning. However, in some instances, persistent symptoms may require more intensive interventions.
