Chronic Unilateral Vestibulopathy

Background

Chronic Unilateral Vestibulopathy occurs when one inner ear has long-term dysfunction, leading to imbalance, dizziness, and difficulty with motion tolerance. Unlike acute vestibular conditions, symptoms persist but may fluctuate over time.

Causes

This condition may be due to viral infections, Meniere’s Disease, vestibular migraines, trauma, or aging-related degeneration. It results from the brain not adequately compensating for the injury. Inadequate compensation may stem from alcohol use, sedative medication use (like benzodiazepines of meclizine), sedentary lifestyle, stress/anxiety or depression, migraine or other causes yet to be understood.

Treatment

Vestibular rehabilitation therapy is the primary treatment to improve balance and reduce dizziness. It is important to avoid vestibular suppressant medications as these reduce the brain's ability to heal and adapt to the inner ear weakness. Patients may also benefit from lifestyle modifications and, in some cases, medications to manage symptoms.
