See how a type of movement called the Epley maneuver can resolve one type of vertigo

BPPV, benign paroxysmal positional vertigo, occurs when a calcium crystal breaks off and is floating around in the inner ear. This video describes how someone suffering from this type of vertigo can determine if this is an issue and how treatment involves a movement called the Epley maneuver.

Vertigo may be reduced by retraining your brain with visual fixation

In this video podcast neuroscientist Andrew Huberman describes one way to help alleviate dizziness and motion sickness symptoms. He suggests visual anchoring—fixating your vision on a point several feet away and moving closer to it, if possible, or fixating your vision on your extended finger and slowly moving it toward your nose and away again.

Vertigo is considered a subtype of dizziness

This two-minute video explains vertigo—a subtype of dizziness—and its many potential causes. It explores the vestibular system, the inner ear system, which typically governs our sense of stability, and details its anatomy.

Peripheral vertigo is a type of dizziness caused by disturbances the inner ear

This type of vertigo can be triggered by several factors including viruses that cause inflammation in the inner ear, Ménière's disease, or benign paroxysmal positional vertigo, which can cause irregular nerve impulses that cause dizziness.

Vestibular Paroxysmia is often overlooked as a vertigo-causing diagnosis

VP causes brief, recurrent episodes of vertigo. It's often mistaken for the more common "benign paroxysmal positional vertigo," but its vertigo episodes are typically shorter and triggered by specific head movements. The condition is caused by compression of the eighth cranial nerve. Other symptoms that accompany it are nausea and unsteadiness and, more rarely, tinnitus and hearing changes.

Vertigo is a mismatch of information between the eyes and the ears

Both vertigo and motion sickness can be caused by mismatches between visual and auditory inputs.The brain relies on inputs from the eyes, inner ear, and receptors in muscles and joints to orient the body. When the eyes suggest movement but other signals suggest the body is stationary dizziness and nausea can occur.

Studying involuntary, rapid eye movements is a key part of vertigo diagnosis

A doctor will look at a vertigo patient's rapid, uncontrollable eye movements—formally called nystagmus—to better understand its causes. When a patient is lying down with their head turned and their eyes spin in a certain position and stop it's likely a peripheral cause, but if the spinning doesn't stop or it changes direction it's more likely a central nervous system issue.

Vertigo can last for minutes—or months—and may occur periodically

Vertigo can be caused by a variety of conditions, including as a side effect of medication, but if it comes on suddenly and is accompanied by other symptoms including difficulty with speech or weakness on one side of the body it's important to go to the emergency room to get checked for a stroke. For recurring vertigo, care teams can teach patients exercises to limit panic, lessen nausea and teach the brain to better tolerate head movements.

The word 'vertigo' derives from the Latin 'vertere,' meaning to turn

Beyond the word's origin, this article makes clear that fuzzy definitions of the disorder make it confusing for patients to describe it.
