5 Key Tests Your Doctor May Use to Diagnose Vertigo
Cracking the Vertigo Code
When you're experiencing vertigo, figuring out the cause is crucial for proper treatment. Doctors have several tests up their sleeves to get to the root of your spinning sensations.

The Head Impulse Test: A Quick Check for Inner Ear Issues
This simple yet effective test involves the doctor quickly turning your head while you focus on their nose. If your eyes can't stay fixed on the target, it may indicate an inner ear problem. It's a quick way to distinguish between central (brain-related) and peripheral (inner ear) causes of vertigo.
Dix-Hallpike Maneuver: Uncovering BPPV
This test is specifically designed to diagnose Benign Paroxysmal Positional Vertigo (BPPV), a common cause of vertigo. The doctor will quickly lay you back with your head turned and tilted, watching for characteristic eye movements. If BPPV is present, this maneuver often triggers brief but intense vertigo.
Electronystagmography (ENG) and Videonystagmography (VNG)
These tests use electrodes or video cameras to record your eye movements. They can detect abnormal eye movements called nystagmus, which often accompany vertigo. ENG and VNG help pinpoint issues in the vestibular system and can distinguish between different types of vertigo.
Imaging Tests: Looking Inside
In some cases, your doctor may order an MRI or CT scan to rule out more serious causes of vertigo like tumors or strokes. These imaging tests provide detailed pictures of your brain and inner ear structures. They're especially important if you have additional neurological symptoms beyond vertigo.
FAQs

How long do vertigo tests take?
