There is exciting new research into balance issues such as vertigo and chronic dizziness. If you suffer from any kind of balance disorder, you probably already know that these issues can stem from fluid levels in your inner ear. This new research is exploring the possibility that balance disorders could be spotted and maybe even alleviated with MRI magnets!

At Johns Hopkins in 2011, researchers discovered something: inner ear fluid is influenced by the magnetic field of an MRI. Since we have already known for a while that vertigo and other balance disorders can be caused by buildup of fluid in the inner ear, they looked at MRI magnets as a way to potentially treat those conditions.  

MRI magnets can exert a pulling force on the inner ear fluid, and researchers hope that they may be able to manipulate inner ear fluids to relieve the problems caused by inner ear issues.

As it stands, uncomfortable and invasive testing protocols are necessary to diagnose and treat imbalance and dizziness conditions such as vertigo. This makes the painless MRI procedure a welcome development for future diagnosis and care.

The Inner Ear and Balance

Approximately 40% of adults experience episodes of imbalance and dizziness at least once during a lifetime. Sufferers may complain of feelings of vertigo and spinning or dizziness. These episodes may also cause people to feel faint or lightheaded and they may become disoriented, confused, or have blurred vision.

• If you become dizzy feel unbalanced on repeated occasions, first check with your doctor, who may then refer you to a specialist or audiologist for testing.
• These symptoms can have different causes. Aside from inner ear fluid disturbance, some medications or even an injury to the head can result in feelings of vertigo or dizziness as well.

When you see an audiologist or specialist, testing may include:

• An MRI or CT scan
• Computerized Dynamic Posturography (CDP): a test of balance function and motor control in changing conditions.
• Electronystagmography (ENT): this test monitors spontaneous eye movements, and includes eye evaluations.
• Vestibular Evoked Myogenic Potential (VEMP) is a test that observes the inner ear’s sensory cells and vestibular nerve to evaluate if they are functioning correctly.

A hearing test may also be part of the visit to your audiologist, to make sure there is no hearing impairment that accompanies the dizziness.

If you have had several dizzy spells or have felt unbalanced, see your general practitioner or audiologist pinpoint the cause.
