Description
-
It is a disorder characterized by a sudden severe attack of vertigo caused by inflammation of the vestibular nerve.
-
Commonly preceded by attack of URTI .
Symptoms
Vestibular neuronitis may occur as a single, isolated attack of severe vertigo lasting 7 to 10 days, but many people have additional attacks of milder vertigo for several weeks thereafter.
The first attack of vertigo is usually the most severe.
The attack of vertigo is accompanied by nausea, vomiting, and nystagmus . The vertigo is severe at first, and gradually subsides over the course of several days, with residual imbalance lasting up to several months. People do not have tinnitus ,and hearing is usually not affected.
Although vestibular neuronitis and labyrinthitis may be closely related in some cases, vestibular neuronitis is generally distinguished from labyrinthitis by preserved auditory function.
Diagnosis
- -Hearing tests
- -Tests for nystagmus
- -(MRI) of the head should be done to make sure the symptoms are not caused by another disorder, such as a stroke.
Treatment
- -Drugs such as meclizine relieve vertigo
- -Drugs such as prochlorperazine to relieve vomiting
- -Sometimes corticosteroid drugs such as prednisone
- -Intravenous fluids if vomiting persists
- -Physical therapy
