Vestibular neuronitis

Vestibular Neuronitis is a condition characterized by a sudden onset of vertigo due to inflammation of the vestibular nerve. This nerve is responsible for sending balance and head position signals from the inner ear to the brain.

Causes

The exact cause of vestibular neuronitis is unknown, but it is often associated with viral infections such as the herpes simplex virus. Other potential causes include bacterial infections, autoimmune diseases, and certain medications.

Symptoms

The primary symptom of vestibular neuronitis is severe vertigo, which can last for several days. Other symptoms may include nausea, vomiting, and difficulty with balance. Some people may also experience a feeling of fullness or pressure in the ear, tinnitus (ringing in the ear), and hearing loss.

Diagnosis

Vestibular neuronitis is typically diagnosed based on the patient's symptoms and a physical examination. Tests such as the Dix-Hallpike maneuver or electronystagmography may be used to confirm the diagnosis. In some cases, an MRI or CT scan may be performed to rule out other conditions.

Treatment

Treatment for vestibular neuronitis primarily involves managing symptoms. This may include medications to reduce vertigo and nausea, as well as physical therapy exercises to help improve balance. In severe cases, hospitalization may be required.

Prognosis

The prognosis for vestibular neuronitis is generally good, with most people experiencing a complete recovery within a few weeks. However, some people may continue to experience balance problems or recurrent episodes of vertigo.
