Balance and Vestibular Disorders Explained

It helps to separate three common sensations that are often grouped together. Vertigo is the illusion of movement, usually spinning. Presyncope is the feeling that you might faint, often linked to blood pressure or cardiovascular causes. Disequilibrium is a sense of unsteadiness or imbalance, particularly when walking. People can experience more than one of these at the same time. Identifying which is dominant often points toward the underlying cause.

Most balance disorders fall into a small number of recognisable patterns based on when the dizziness happens, how long it lasts, what seems to trigger it, and whether anything else accompanies it. That history is usually what points toward a diagnosis well before any testing is done.

The conditions below cover the most common causes seen in audiology and ear, nose and throat practice. Some are straightforward to resolve. Some are managed over time rather than cured. The connection between hearing and balance is not always obvious - both functions share the same inner ear structure, which is why an audiologist is often one of the first clinicians involved and why a hearing assessment frequently forms part of the diagnostic picture. If something in the list below sounds familiar, it is worth following up rather than waiting

Common balance and vestibular conditions

Benign paroxysmal positional vertigo (BPPV)

BPPV is the most common cause of vertigo. It produces brief, sudden episodes of spinning - usually lasting less than a minute - triggered by specific head movements such as rolling over in bed, looking up, or bending forward. Between episodes, most people feel entirely normal, which is one of the reasons it can feel bewildering. The cause is mechanical: small calcium carbonate crystals (otoconia) that normally sit in one part of the inner ear balance organs become dislodged and migrate into one of the structures involved in sensing head movements - semicircular canals. Once there, they create an abnormal signal during movement that the brain interprets as spinning.

Diagnosis involves a specific manoeuvre called the Dix-Hallpike, which places the head in a position that provokes the characteristic eye movement (nystagmus) if BPPV is present. The pattern of that eye movement - its direction, how quickly it appears, and how quickly it settles - tells the clinician which of the three semicircular canals is involved. The posterior canal is most commonly the source, though the horizontal and anterior canals can also be affected. Treatment is a repositioning sequence called the Epley manoeuvre, which guides the displaced crystals back to where they belong. Resolution rates are high, often after one or two treatments. It is common to feel off-balance for a few days afterward, but this usually settles on its own. BPPV can recur, particularly in older adults, but responds well to the same approach each time (Bhattacharyya et al., 2017).

Vestibular neuritis

Vestibular neuritis arrives suddenly and hard. Most people describe waking with severe vertigo, nausea, and a pronounced sense of being pulled or thrown, often to one side. Moving makes it worse. The episode typically peaks within hours and then gradually settles over days to weeks, though a residual unsteadiness can persist for longer. Hearing is preserved, which distinguishes it from labyrinthitis, where the adjacent cochlea is also affected.

The cause is thought to be viral inflammation of the vestibular nerve. During the acute phase, the brain receives mismatched signals from the two ears, which drives the vertigo and instability. Over time the brain recalibrates to work with this asymmetry, a process called central compensation. Vestibular rehabilitation is the most meaningful intervention for recovery. Corticosteroids may improve recovery on vestibular testing, but this does not consistently translate to better day-to-day function (Strupp et al., 2004; Leong et al., 2021).

Meniere's disease

Meniere's disease produces episodic attacks of vertigo lasting from twenty minutes to several hours, accompanied by fluctuating hearing loss, tinnitus that sounds like ocean-waves crashing, and a sensation of pressure or fullness in the affected ear. The combination is characteristic. The unpredictability of attacks is often what patients find hardest to manage. The underlying mechanism is thought to involve excess inner ear fluid pressure (endolymphatic hydrops), though the exact relationship to symptoms is still being studied.

Diagnosis relies on the pattern of symptoms over time and audiometric evidence of fluctuating low-frequency hearing loss. In early stages, hearing often recovers between episodes. Over time, the loss can become more permanent. Audiological monitoring is an important part of care. Management ranges from dietary and medical approaches through to intratympanic therapy in more persistent cases (Lopez-Escamez et al., 2015).

Vestibular schwannoma (acoustic neuroma)

A vestibular schwannoma is a benign, slow-growing tumour arising from the vestibular nerve. Despite the name, it most often presents with hearing-related symptoms:
