Vestibular Neuronitis: Causes, Symptoms, and Treatment
Vestibular neuronitis is an inner ear disorder that affects the vestibular system, which is responsible for maintaining balance and spatial orientation. This condition is also known as vestibular neuritis or labyrinthitis.
Causes of Vestibular Neuronitis
Vestibular neuronitis is caused by inflammation of the vestibular nerve, which connects the inner ear to the brainstem. The inflammation is usually the result of a viral infection, such as a cold or flu. Other possible causes include bacterial infections, head injuries, and tumors.
Symptoms of Vestibular Neuronitis
The most common symptom of vestibular neuronitis is sudden and severe vertigo, which is a sensation of spinning or whirling. Other symptoms may include:
- Nausea and vomiting
- Difficulty walking or standing
- Loss of balance or coordination
- Blurred vision or nystagmus (involuntary eye movements)
- Headache
Treatment of Vestibular Neuronitis
There is no cure for vestibular neuronitis, but the symptoms can be managed with medication and physical therapy. Medications such as antihistamines, antiemetics, and benzodiazepines may be prescribed to relieve vertigo, nausea, and anxiety. Physical therapy may include exercises to improve balance and coordination, as well as habituation exercises to reduce sensitivity to motion.
In most cases, the symptoms of vestibular neuronitis will improve within a few weeks to a few months. However, some people may experience recurrent episodes of vertigo or balance problems. If you are experiencing symptoms of vestibular neuronitis, it is important to seek medical attention to rule out other possible causes and to receive appropriate treatment.
