Vertigo may be reduced by retraining your brain with visual fixation

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.

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.

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.

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.

Eating too much salt can worsen vertigo

High salt intake can cause fluid retention in the inner ear, worsening vertigo. Slashing sodium amounts (and caffeine and alcohol consumption) are particularly recommended for those suffering from Ménière's disease to help stabilize inner ear fluid levels.

Pets can experience vertigo, particularly older dogs

This type of dizziness is often caused by disorders of the vestibular system, and in dogs is often referred to as "old dog vestibular disease" because it tends to occur in older animals. The condition tends to resolve on its own in days or weeks. Vertigo is less common among cats than dogs, and in felines is typically caused by inner ear infections or other causes including a tumor.

A BPPV patient describes how a neck massage fueled crippling vertigo

The pressure, she says, dislodged tiny crystals in her inner ear that are crucial to balance. The condition is called benign paroxysmal positional vertigo, or BPPV.

Longer-duration space missions may amplify astronaut motion sickness

NASA is using the Kraken, a 50-foot-long, 100-ton US Navy research device, to simulate space motion sickness and vertigo and test possible recovery strategies, including testing out different, specific head movements. The Kraken, located at Wright-Patterson Air Force Base near Dayton, Ohio, can rotate participants at exposures of up to 3G.

20% of patients with migraines may also experience vertigo

Vestibular migraine is a common cause of vertigo, affecting approximately 20% of patients with migraine. It's the most common cause of recurrent, sudden-onset vertigo.

What is space sickness?

Mix motion sickness minus gravity with a host of other variables, and you’ve got a recipe for space adaptation syndrome. It can hit anyone, even astronauts who escaped the issue previously. This article details the history and science behind space sickness.

Why do some people always get lost?

Using GPS, anthropological data, and VR, scientists have learned that one's sense of direction is largely influenced by upbringing. A person's wayfinding ability can be measured by how accurately they point toward an out-of-sight location, a challenge further complicated by imagining they're somewhere else and pointing toward a third location. Anxiety, safety concerns, and dislike of wandering can negatively impact one's sense of direction, which can improve with practice.

The science of optical illusions

The human brain has developed cognitive shortcuts to help us navigate in a world where our visual senses are constantly bombarded of information. But these shortcuts can also be exploited, tricking the brain into telling us something is happening when it really isn't. This short video unpacks the neuroscience behind some of the most common (but perplexing) optical illusions.

Smell retraining can help people with anosmia learn to smell again

Olfactory training, which involves repeatedly smelling a selection of strong odors, teaches your brain to familiarize itself with experiencing smells over a lengthy period, typically multiple months. This can be useful for patients who lose their sense of smell for myriad reasons.

People with tinnitus should avoid silence—sound-rich environments distract the brain

This podcast from an audiologist discusses common questions about tinnitus. It notes that tinnitus could be described as a phantom sound associated with hyperactivity in the brain. It's linked with loud sound exposures above 85 decibels, hearing loss associated with aging and stress, among other factors.

Watch what depression does to the brain

This video explores the neurobiology of depression and why unraveling the complexities of this disease and its etiology will potentially improve treatments. Effective depression treatment, as this video highlights, can eventually make a depressed brain look like a healthy one on brain scans.

Déjà vu is a memory illusion involving brain regions correcting inaccurate memories

Neuroscientists suggest the phenomenon is your brain recognizing that this feeling of familiarity is incorrect, showing off the brain's internal fact-checking system. Younger people experience déjà vu more often because their brains have higher excitatory activity and stronger memory monitoring systems.

Scientists are learning to guide your dreams using sound and touch

Researchers are using a technique called "targeted dream incubation"—where stimuli like sounds or vibrations are introduced as you drift off—to influence dream content and potentially improve creativity, memory consolidation, and PTSD treatment. With the same mechanism, companies could theoretically target sleeping consumers with brand suggestions while they're unaware and neurologically susceptible, or assist in reducing nightmares.

Neural replays in mice help explain food aversions

Princeton University scientists published research in 2025 analyzing how mice learn to associate certain foods or flavors with feeling ill—even when there’s a time gap between eating something and feeling sick. The work, performed with grape Kool-Aid and injections of a substance that made mice sick, traced the literal “gut reaction” of how gut distress signals are linked to neural replays of what the mouse ate.

After 25 people used virtual reality headsets to practice flying with virtual wings—flapping their arms—their visual cortex responded to the wings almost as if they were real arms, treating them as body parts.

Why 'spacing out' or dissociating may help reduce trauma awareness

Dissociation may have developed as a defense mechanism in the brain to help navigate intense emotional or physical situations by providing out-of-body experiences that put distance between the mind and the environment. However, in about 1.1% and 1.5% percent of the general population, a severe form of this separation can produce alternate identities, or alters.

Bestselling author Daniel Pink breaks down how to approach each part of the plan and introduce these habits to your life today.

Corrective vision technologies rely on the bending of light waves

When focusing on an object, muscles change the shape of the lens, which refracts incoming light such that it focuses at the retina. If the cornea is unable to bend light correctly, lenses or contact lenses can provide supplemental refraction to ensure a focused image is produced.

Changes in vision or eye pain can be early MS symptoms

This occurs due to myelin degradation around the optic nerve, impairing its ability to transmit visual information to the brain. Individuals may especially experience eye symptoms after exercising or taking a hot shower because boosted body temperatures slow down nerve function in nerves already damaged by MS.

Negative thinking spirals are often the result of uncertainty and anxiety

Psychologists suggest that a helpful way to deal with negative thinking is to remind oneself that setbacks can simply be setbacks, rather than a grand catastrophe. Positive self-talk, focusing on the factors we can control, and being altruistic are other tools that can help one escape negative thinking.
