Labyrinthitis is an inner ear disorder characterized by the inflammation of the labyrinth, the delicate organ in the inner ear that controls hearing and balance. This inflammation causes a sudden onset of severe dizziness and vertigo.
read more about labyrinthitis ...The underlying mechanism of onset usually involves a viral infection, often following a cold or flu. The virus causes swelling of the nerves within the labyrinth, disrupting the transmission of accurate balance and motion information to the brain.
Vertigo begins suddenly with a spinning sensation that worsens with head movement. Severe nausea, vomiting, and imbalance limit standing or walking. Eye movements show nystagmus during acute attacks. Hearing can drop in the affected ear with ringing or fullness. Symptoms improve over days as the brain compensates, though imbalance can linger.
Diagnosis involves ruling out more serious neurological problems. The doctor performs tests to check eye movement and balance. Imaging tests are sometimes used to rule out stroke or tumor. Recovery is typically managed with medication to control dizziness.
Labyrinthitis directly impacts vision by causing uncontrolled eye movements (nystagmus). The disruption of the inner ear balance signals confuses the brain, causing the eyes to flick back and forth rapidly, making it difficult to focus or stabilize vision.
Therapeutic strategies focus on managing symptoms and retraining the brain. Vestibular rehabilitation therapy (VRT) involves specific exercises to help the brain compensate for the incorrect balance signals. Anti-nausea and anti-dizziness medications are used initially.
No, vertigo is a symptom. Labyrinthitis is an inflammation that causes vertigo.
Symptoms typically lessen within a few weeks, but full recovery of balance can take several months of therapy.
No, the inflammation itself is not contagious, but the cold or flu virus that causes it can be spread to others.
Seek emergency care if vertigo is accompanied by sudden hearing loss, high fever, or fainting. In some cases, labyrinthitis can cause "Nystagmus" (involuntary eye jumping), which a doctor uses to diagnose the severity of the vestibular nerve inflammation.
