Balance disorders: causes, how to tell them apart and when to see a doctor

The room spins, the floor sways, or when walking you are suddenly pulled to the side: balance disorders are unsettling and noticeably restrict everyday life. Many people experience them at least once in their lives, and they become more frequent with increasing age. Dizziness is not a condition of its own but a leading symptom with many possible causes. That is exactly why it is worth looking more closely instead of leaving it at a general circulation tip. This guide shows you the decisive distinction between a cause in the inner ear and one in the brain, explains the common positional vertigo together with the manoeuvres that fix it, and makes clear which warning signs mean an emergency. This brings you noticeably closer to the cause than the blanket advice simply to drink more.

How balance arises

Your sense of balance is an interplay of several systems. The balance organ in the inner ear reports rotations and changes in head position, the eyes provide images of the surroundings, and the position sense from muscles and joints reports the body's posture in space. Only from the comparison of these three sources does the secure feeling of standing upright and stable arise. The brain, above all the brainstem and cerebellum, constantly computes this information into a coherent picture. If the systems deliver contradictory signals or one fails, dizziness arises. Similar to motion sickness, when the eyes and inner ear report different movements, the body then reacts with dizziness and often with nausea. Doctors broadly distinguish spinning vertigo, in which everything turns as on a carousel, swaying dizziness, in which you feel as if on a ship, and unspecific light-headedness.

Which dizziness lasts how long?

An important clue is how long the dizziness lasts and what triggers it. Attacks lasting only seconds that are triggered by a change of head position point to positional vertigo. Attacks lasting twenty minutes to several hours, often with ear symptoms, fit Menière's disease, while a vestibular migraine can last minutes to days. An intense spinning vertigo that lasts for several days points to vestibular neuritis, but more rarely can also be centrally caused. A persistent swaying dizziness over weeks is often functional. These time patterns are a valuable building block for the right classification.

Vestibular or central?

The most important fork is the question of whether the dizziness comes from the balance system of the inner ear, that is vestibular, or from the brain, that is central. This is so important because vestibular causes are usually benign and treatable, while central causes can represent an emergency. The overview below helps you with the classification but does not replace a diagnosis. In practice the boundaries are not always sharp, and especially at the start a central cause can resemble a harmless one, which is why in case of doubt the medical judgement always decides.

The most common causes in the inner ear

Most balance disorders arise in the inner ear and are treatable. These vestibular causes can be recognised by typical patterns, above all by the type of dizziness, its duration and the accompanying symptoms. Three conditions stand out here.

Benign positional vertigo

Benign positional vertigo is the most common cause of attack-like spinning vertigo. Tiny crystals, so-called ear stones, come loose and get into the semicircular canals of the inner ear, where they do not belong. With every head movement they irritate the fine sensory cells there and report to the brain a rotation that is not happening at all. A change of head position, for example when lying down, turning over in bed or bending, then triggers brief, intense spinning attacks that usually last less than a minute, often with nausea. As unpleasant as that is, the cause is harmless and very treatable. Typically the dizziness disappears again when lying still, and only the next change of position triggers it once more, for example when turning over in bed in the morning.

Vestibular neuritis

With vestibular neuritis the balance nerve is inflamed, usually from a viral infection. Typical is a sudden, intense spinning vertigo that lasts for days, with nausea, vomiting and a tendency to fall, but without hearing loss. The symptoms usually improve within one to two weeks, while the brain compensates for the disturbance. To support this, targeted balance training is often recommended early, which speeds up this natural recovery.

Menière's disease

With Menière's disease there are recurring attacks of spinning vertigo, hearing loss, ringing in the ears and a feeling of pressure in the ear. An attack usually lasts twenty minutes to several hours. Because the ear and balance are affected together here, ear symptoms are an important clue. Between the attacks those affected can often be free of symptoms, but over the years the hearing loss can increase, which is why an early assessment is important.

Positional vertigo and the repositioning manoeuvres

With positional vertigo in particular, it shows how much a precise diagnosis brings. With a simple positioning test, the Dix-Hallpike manoeuvre, the medical practice checks whether and on which side crystals sit in the canal. The head is deliberately brought into a certain position, and the positional vertigo can be recognised from the typical eye movements that occur. If the suspicion is confirmed, a repositioning manoeuvre follows directly.

The best known is the Epley manoeuvre. The head is brought into certain positions one after another in a fixed sequence, so that the dislodged crystals, following gravity, move out of the canal and back to their actual place. The Semont manoeuvre works similarly. These manoeuvres are very effective with correctly identified positional vertigo and often bring clear improvement after just a few rounds, without any medication being needed. It is important that the correct side and the correct canal are known, because a manoeuvre on the wrong side does not help. That is why it should be done after a medical diagnosis, where appropriate with guided exercises for home. Doing it on your own and without a confirmed diagnosis is not advisable, also because more serious causes have to be ruled out first. After a successful manoeuvre the dizziness can linger in the first hours before it settles, and in some cases several rounds are needed until it disappears completely.

When it is central and dangerous

Central causes affect the brain itself. Besides a stroke, multiple sclerosis can also be behind it, in which inflammatory lesions in the brainstem or cerebellum trigger dizziness, sometimes even as a first sign. Unlike with inner-ear dizziness, further neurological complaints that go beyond the dizziness itself are often in the foreground here. This should be considered especially in younger people with changing neurological complaints. Read more in our article on multiple sclerosis. A vestibular migraine, that is dizziness as part of a migraine, is also a common and often unrecognised cause. It can also occur entirely without headache, which makes the assignment harder, and is one of the most common forms of dizziness of all.

Other causes of balance disorders

Not every dizziness comes from the inner ear or the brain. A common form is functional or phobic swaying dizziness, in which there is no damage, but the dizziness is nonetheless real and often linked to tension or anxiety. Typically it is stronger in certain situations such as in crowds, on wide squares or when climbing stairs, and it can remain after a physical vestibular illness. Common too are a drop in blood pressure on standing up, side effects of medications and a declining interplay of the senses in older age. Especially in older age several factors often come together, such as declining eyesight, unsteady legs and several medications at once, which increases the risk of falls. How dizziness can be classified in general is covered in our article on dizziness.

What you can do yourself

With harmless balance disorders you can do quite a bit yourself, once serious causes have been ruled out. It is important to stay in motion instead of taking it easy out of fear of the dizziness, because over time the brain learns to compensate for the disturbance. With acute spinning vertigo it helps to fix on a steady point and to move slowly and in a controlled way, instead of making jerky head movements. Do not get up abruptly in the morning, but first sit on the edge of the bed and wait a moment until the circulation gets going. Ensure good vision with the right glasses and safe paths without trip hazards to avoid falls. Firm, flat shoes and good light in the home help in addition. Special balance exercises, so-called vestibular training, support the recovery and are often guided by physiotherapists. Movements are deliberately practised that initially trigger mild dizziness, so that the brain gets used to the stimuli and compensates for them better over time. Patience pays off, because the successes often only show after several weeks of regular practice.

What the doctor does

The good news is that the classification often succeeds without elaborate equipment. Most important is the conversation with a few targeted questions: what does the dizziness feel like, how long does it last, what triggers it and which accompanying symptoms are there? Added to this are a check of the eye movements, positioning tests for positional vertigo and a look at gait and stance. Depending on the suspicion, a hearing test, a blood pressure measurement while lying and standing or a magnetic resonance scan follow when a central cause has to be ruled out. Studies show that most forms of dizziness can be reliably classified with just a few targeted questions and bedside examinations, entirely without elaborate equipment.

The bottom line: balance disorders are usually harmless and treatable, especially the common positional vertigo. What matters is the distinction between inner ear and brain. Watch for the warning signs, take neurological accompanying symptoms seriously and have persistent or unclear dizziness assessed. Even a single attack with warning signs is reason enough to seek medical advice promptly. A good description of your symptoms and an up-to-date medication list help the medical practice a lot with this. This way an unsettling symptom becomes a problem that can be classified well and, in most cases, treated effectively.
