Besides the six most common subtypes, the setup question Which type of vestibular condition? lists some less common ones. Here is a short, plain description of each. If you have been given one of these names, your ENT, neurologist or audiologist is the best person to explain what it means for you.
Bilateral vestibulopathy
The balance organs on both sides work less well than they should. People often feel unsteady, especially in the dark or on uneven ground, and may notice the world bouncing when they walk (called oscillopsia). It is usually a steady problem rather than spinning attacks.
Vestibular paroxysmia
Very short, frequent spells of vertigo, often lasting seconds, sometimes many times a day. It is thought to come from a blood vessel pressing on the balance nerve. A neurologist or ENT usually makes the diagnosis.
Superior canal dehiscence (SCDS)
A thin or missing patch of bone over one of the balance canals in the inner ear. People may get dizziness with loud sounds or straining, hear their own voice or heartbeat loudly in one ear, or have hearing changes.
Perilymph fistula
A small leak of inner ear fluid, often after a head injury, barotrauma (for example diving or flying) or heavy straining. It can cause dizziness and hearing changes.
Acoustic neuroma (vestibular schwannoma)
A slow-growing, non-cancerous growth on the nerve between the inner ear and the brain. It often causes gradual hearing loss and tinnitus in one ear, and sometimes unsteadiness. It is usually found on a scan.
Cervicogenic dizziness
Dizziness or unsteadiness thought to come from the neck, usually with neck pain or stiffness. It is diagnosed once other causes have been ruled out.
Central vertigo
Vertigo caused by a problem in the brain itself, such as a stroke, multiple sclerosis or other conditions, rather than the inner ear. Any sudden vertigo with signs such as double vision, slurred speech, facial droop, weakness, numbness or being unable to walk needs emergency care.
Not sure yet
Many people track their spins for months before they have a name for them. Choosing Not sure yet is fine, and a good diary can help your doctor get there.
This is general information only. It cannot tell you what is causing your symptoms. Please speak to your GP, ENT, neurologist or audiologist about your own situation.
