A common and frustrating question from people with ongoing dizziness is:
“All my tests are normal, so why am I still dizzy?”
In most cases, these “normal tests” refer to MRIs, CT scans, or blood work. While useful for ruling out serious conditions, they’re not designed to evaluate the vestibular system in detail.
Many vestibular disorders, like PPPD, vestibular migraine, or chronic vestibular hypofunction, are functional in nature. They involve how the brain interprets signals from the inner ear, eyes, and body, rather than something visible on a scan.
That’s why choosing the right diagnostic pathway is essential.
Persistent dizziness should be assessed through a comprehensive vestibular evaluation, a series of functional tests that examine key systems involved in balance. This includes assessing:

  • Vestibulo-ocular reflexes
  • Oculomotor function and gaze stability
  • Balance and positional responses
  • And how the brain processes motion and visual input

 

The exact test battery depends on the person’s history and symptoms, but when performed properly, it can reveal subtle dysfunctions that imaging alone cannot detect. So if your tests were “normal” but you’re still experiencing dizziness, it may simply mean the right tests haven’t been done yet. The path to recovery starts with the right evaluation.

Optokinetic Stimulation

Optokinetic stimulation is a treatment tool that uses moving visual patterns (like stripes or dots) to help desensitise the brain to motion and reduce symptoms of dizziness, disorientation, or visual overload. It’s particularly helpful when visual environments trigger or worsen your symptoms.

Skull Vibration Test

The Skull Vibration Test uses a gentle vibration behind the ear to stimulate the balance organs of your inner ear and detect if there’s a difference between the left and right sides. It is often used as a simple but powerful screening tool when dizziness or imbalance seems one-sided.

Videonystagmoscope (VNS)

VNS is a diagnostic tool that uses infrared video goggles to directly observe and analyse eye movements in real time. Since the eyes and inner ear are functionally linked, monitoring these movements helps determine whether a patient’s dizziness or imbalance is related to peripheral vestibular dysfunction or central causes.

Video Head Impulse Test (VHIT)

The VHIT evaluates how well your vestibulo-ocular reflex (VOR) is working — the reflex that keeps your eyes steady when your head moves. It helps us determine whether your inner ear canals are functioning properly, especially when you feel dizzy or unfocused during quick movements.
