Why vertigo is so hard to pin down
New, sudden dizziness can have urgent causes and should be medically assessed first (see When to get urgent care, below).
Many people with lingering vertigo or dizziness are confused and frustrated about their diagnosis. They've heard it might be Meniere's, vestibular neuritis, a type of BPPV or PPPD, sometimes with overlapping explanations like an acoustic neuroma, occipital neuralgia or vestibular (silent) migraine, but no one has committed to an answer. Most have been offered medication. Many feel their testing wasn't specific enough to point to a plan. The way forward usually starts with more specific testing, because the right test comes before the right treatment.
What a thorough vestibular evaluation looks like
The inner ear doesn't work alone. Your eyes, neck, brain and blood flow all feed into your sense of balance, so a thorough evaluation looks at each of them:
- Video eye movement recordings (VNG): drifts of the eyes at rest in the dark, how the eyes follow moving patterns (optokinetics), how well they stay steady when the head moves (VOR) and how well that reflex can be overridden (VOR suppression).
- Computerized balance testing on firm and unstable surfaces, eyes open and closed, in different head positions.
- Movement in every direction: straight-line movement, such as being raised and lowered on a table, as well as turning.
- Timing and coordination testing.
- Blood flow to the brain and CO2, when the autonomic system is part of the picture.
- The neck: a hands-on cervical exam and palpation.
- Eye alignment and a bedside neurological exam.
Even in hospitals, these tests are usually split across separate departments and appointments, and rehab happens somewhere else again. Having them all in one place, read together and followed by rehab built from the results, is rare. When that happens, the findings can turn directly into what you train.
Why looking at several systems at once matters
No single test explains most lingering dizziness. The value comes from one clinician reading all of the results together: the inner ear, the eyes, the neck, balance, and blood flow and autonomic responses. A problem that looks like an inner-ear issue on one test can turn out to involve how the brain combines signals, how the neck is moving, or how blood flow responds when you're upright. Seeing those systems side by side is what turns "we're not sure" into a specific plan.
That synthesis is what our clinic is built around.
Questions worth asking any provider
More practitioners now offer help with dizziness and vertigo. Whoever you see, these questions can help you judge whether your care will be specific to you:
- Will my testing tell a central (brain) problem apart from a peripheral (inner ear) one?
- Will you test movement in every direction, not just turning?
- Will you look at my eyes, neck, balance and blood flow together, or only one of them?
- Will I see my own recordings and have them explained?
- Will my treatment be chosen from my test results, or is it a standard set of exercises?
Common misconceptions
- "It's crystals in your ear." Loose crystals (BPPV) are real, but they're often treated as the only explanation. Repositioning maneuvers like the Epley can help even without a loose crystal, because they stimulate the balance canals, otoliths and hair-cell signaling. When every dizzy patient gets the same maneuver, the real problem can be missed.
- Central and peripheral problems are treated the same. They often aren't told apart, yet they call for different care.
- "It's just anxiety" or "just take medication." Without a detailed workup, it's hard to know what's actually driving the symptoms.
What recovery looks like
When rehab targets the specific challenge points that testing found, what improves in a session tends to carry closely into daily life. Early signs often show up right away: a stripe pattern gets easier to follow, the same challenge causes less dizziness, you can do it for longer, and you have more bandwidth for other tasks.
How long care lasts depends on the findings. Chronic patterns like PPPD may take longer, or may respond quickly to an intensive. BPPV is usually more acute-style care. Good plans share the same shape: frequent care up front, then tapering support.
An example: when the usual explanation didn't fit
A recent patient had about two weeks of sudden, episodic dizziness with no clear trigger, and she had stopped working. BPPV workups didn't fit.
Her eye recordings showed a right-beating nystagmus at rest in the dark, with a leftward drift. In a rotary chair, turning left in the dark neutralized it. Her sessions stacked several therapies at once: stimulation on one side, visual suppression, low-level laser to the cochlear region, peripheral stimulation of the face, active head movements to train the VOR, fixation targets, optokinetics in one direction and bone conduction headphones.
After three days, her nystagmus was much milder. She was walking with less rigidity and more confidence, and she could see it trending toward neutral on her own video. She's now on a home plan with tapering check-ins.
What you can do at home
Home drills work best when they're personalized from your own test results. Examples include:
- balance in different head and neck positions while fixating on a target
- optokinetic stripes, keeping your eyes still or moving with or against them
- head flexion and extension, and chair spins
- line walking with an exaggerated arm swing and fixation targets
- moving to a metronome beat
- sometimes a Brock string for eye teaming, the Troxler effect, or coordination charts
Vestibular problems often overlap with other systems, so a good plan may include more than balance work.
When there's a structural cause
Structural conditions like an acoustic neuroma or Meniere's are co-managed with an ENT. Rehab works hand in hand with the ENT's care, adding a conservative, specific and safe roadmap to improve quality of life.
Is testing hard on you?
Testing can be tiring, and a mild flare the same day is common. Experienced examiners tailor tests to your comfort and feedback without loosening clinical rigor. Test day is below the threshold for lasting change, and we've never seen sustained worsening from it. Many patients say it wasn't as bad as they feared.
When to get urgent care
Go to the emergency room for dizziness with any stroke signs: sudden facial weakness, sudden arm weakness or numbness, slurred speech, sudden confusion or a sudden severe headache. Sudden, unexplained dizziness deserves extra caution.
Vestibular problems can follow a head injury. After a significant concussion, initial imaging can be warranted to rule out bleeding before rehab begins.
Frequently asked questions
Is vertigo always caused by crystals?
No. Loose crystals are one cause. Inner-ear and nerve problems, how the brain processes balance signals, the neck and blood flow can all be involved, which is why specific testing matters.
What's the difference between central and peripheral dizziness?
Peripheral dizziness comes from the inner ear and its nerve. Central dizziness comes from how the brain processes those signals. They call for different care.
Will testing make my dizziness worse?
It can be tiring, with a usually mild flare the same day, but test day is below the threshold for lasting change.
