When the world won't stand still.

• A sudden, intense spinning when you roll over in bed, lie down, or sit up
• Vertigo triggered by tipping your head back — reaching a high shelf, hanging washing, at the salon
• Short bursts of spinning that last seconds to a minute, then settle
• Nausea that comes with the spinning episodes
• A sense that the room keeps moving for a moment even after you've stopped
• Symptoms that come and go in clusters over days, with normal hearing

BPPV announces itself in a very particular way: you turn in bed and the whole room lurches into a violent spin, gripping and frightening — and then, within seconds, it's gone. The attacks are short but intense, and they're tied to movement and position rather than appearing out of nowhere. Many people become afraid to lie down on one side, or learn to move their head slowly and stiffly to avoid setting it off. Crucially, between attacks, hearing is normal and there's no ringing in the ears — a clue that helps separate BPPV from other causes.

Deep inside the ear are tiny calcium crystals (otoconia) that normally help the brain sense gravity and movement. In BPPV, some of these crystals come loose and drift into one of the ear's fluid-filled balance canals, where they don't belong. Now, every time you move your head a certain way, the crystals shift and send the brain a false, exaggerated signal that you're spinning — even though you aren't. It is a purely mechanical problem, not a sign of anything sinister in the brain, which is exactly why it can be corrected mechanically: by guiding those crystals back out of the canal and into the chamber where they belong.

BPPV is one of the few conditions in medicine that can often be diagnosed and cured in the same short visit. Dr. Kumar confirms it with the Dix-Hallpike test — a simple, guided change of head position that reproduces the vertigo for a few seconds and lets him see the tell-tale eye movements that pinpoint which ear and which canal is involved. The treatment is not a tablet but a manoeuvre: the Epley (or a related repositioning technique), a precise sequence of head and body movements that walks the loose crystals back out of the canal. Many patients feel dramatically better the same day. Dr. Kumar also teaches you the movements to do safely at home if it recurs, and avoids unnecessary long-term 'vertigo medicines', which actually slow the brain's natural recovery if overused.

• A sudden onset of intense, constant spinning that lasts for hours to days, not seconds
• Vertigo so severe you can't stand or walk without help, with vomiting
• Symptoms that began during or just after a cold, flu, or viral infection
• The spinning is there even when you keep your head perfectly still (though movement worsens it)
• In labyrinthitis, hearing in one ear is affected too; in pure neuritis, hearing is spared
• Gradual improvement over days, with unsteadiness lingering for a while after

This is vertigo at its most overwhelming. Unlike the brief spins of BPPV, vestibular neuritis arrives as a sustained, relentless spinning that can flatten a person completely — many describe being unable to lift their head from the pillow without violent dizziness and vomiting, sometimes for a day or two. It is genuinely distressing, and because it can come on so suddenly and severely, people often fear the worst. The reassuring part is that this is usually inflammation of the balance nerve, not a stroke, and the body has a remarkable ability to recover from it.

The inner ear sends a constant stream of balance signals to the brain through the vestibular nerve. In vestibular neuritis, this nerve becomes inflamed — usually from a viral infection — and suddenly starts sending faulty, lopsided signals. The brain, receiving strong balance information from one ear and almost none from the other, interprets the mismatch as violent spinning. When the inner ear's hearing part is involved too, it's called labyrinthitis. Over days to weeks, the inflammation settles and, importantly, the brain learns to recalibrate around the change — which is why recovery, helped by the right exercises, is the rule rather than the exception.

Dr. Kumar's first and most important job here is to confirm that this is vestibular neuritis and not a stroke affecting the balance centres — a distinction made carefully at the bedside through specific eye-movement and coordination tests, with imaging when there's any doubt. Once a benign cause is established, the approach is twofold. In the acute phase, short-term medication can ease the worst of the spinning and vomiting — but only briefly, because relying on these drugs too long actually delays recovery. The real treatment is vestibular rehabilitation: a set of graded balance and eye-head exercises that retrain the brain to compensate. Dr. Kumar guides this recovery and arranges vestibular physiotherapy where needed, and most patients return to normal function over a few weeks.

• Attacks of severe spinning that last from twenty minutes to several hours
• Hearing that drops or muffles in one ear, often during or before an attack
• Ringing, roaring, or buzzing in the same ear (tinnitus)
• A feeling of pressure or fullness in the affected ear
• Attacks that come in clusters, then quiet down for weeks or months
• Over time, hearing in that ear gradually becoming worse

Ménière's has a cruel unpredictability to it. An attack can strike with little warning — a roar building in one ear, a sense of pressure, and then hours of disabling vertigo with nausea that leaves a person wrung out. Between attacks, life can feel almost normal, which makes the next one all the harder to live with. The combination of spinning, changing hearing, and ear fullness is the signature that sets it apart from other vertigos, and the slow threat to hearing over the years is what makes getting it properly managed so important.

Ménière's disease is linked to a build-up of excess fluid in the inner ear, the delicate chamber that handles both balance and hearing. When the pressure of this fluid rises, it disrupts both systems at once — producing the vertigo, the muffled or roaring hearing, and the sense of fullness together. Exactly why the fluid accumulates isn't fully understood, but it tends to be a long-term, fluctuating condition rather than a one-off event. Because it threatens hearing as well as balance, the goal of treatment is both to control the attacks and to protect hearing over time.

Because several conditions can imitate it, Dr. Kumar's first step is a careful diagnosis — confirming the pattern of vertigo, hearing change and ear fullness, and arranging a hearing test to document it. Management is then long-term and layered. Day-to-day, simple measures make a real difference: reducing salt, caffeine and other triggers helps lower inner-ear fluid pressure, and Dr. Kumar prescribes medication to reduce the frequency and severity of attacks, along with a rescue plan for when one strikes. Vestibular rehabilitation helps with the unsteadiness between attacks. Throughout, hearing is monitored so it can be protected. The aim is fewer, milder attacks and a life that is no longer ruled by the fear of the next one — and for the great majority, that is very achievable.

• Vertigo together with double vision, slurred speech, or trouble swallowing
• Spinning with weakness or numbness on one side of the body or face
• Severe unsteadiness or falling, out of proportion to the spinning sensation
• Vertigo with a new, severe, or unusual headache (sometimes vestibular migraine)
• Dizziness that is constant and not clearly triggered by head position
• Vertigo appearing for the first time in someone with stroke risk factors

Central vertigo can feel similar to inner-ear vertigo, which is exactly what makes it dangerous to dismiss. The spinning may be less violent than BPPV or neuritis, but it tends to be more persistent, and it often travels with company — a visual disturbance, a clumsy hand, a slur in the speech, an unsteadiness that's worse than the dizziness itself would explain. Vestibular migraine, a common and very treatable cause, can bring vertigo with or without the headache people expect. The honest message is simple: when vertigo arrives with any neurological symptom, it deserves a proper look, not reassurance over the phone.

Most vertigo comes from the inner ear, but a minority arises from the brain itself — specifically the brainstem and cerebellum, the regions that process balance signals. Here the cause isn't loose crystals or inner-ear fluid but a problem in the brain's own circuitry: a reduced blood supply or small stroke, vestibular migraine, multiple sclerosis, or other conditions. This is the vertigo you must not miss, because some central causes are time-critical. It is also where a neurologist's training matters most — telling a harmless inner-ear spin from a brain-based one is a clinical skill, and getting it right decides whether you need reassurance and a manoeuvre, or urgent treatment.

This is where being seen by a neurologist genuinely changes outcomes. Dr. Kumar's role is first to separate central vertigo from the far more common inner-ear causes, using targeted bedside examination — particular patterns of eye movement, coordination, and gait can distinguish the two with surprising accuracy — and arranging brain imaging such as an MRI when the picture warrants it. If a central cause is found, treatment is directed at it: urgent stroke pathways where relevant, preventive treatment for vestibular migraine (which responds very well to the right medication and trigger management), or management of the underlying condition. Where it turns out to be a benign inner-ear problem after all, the greatest gift is often the confident reassurance that it is not a stroke — backed by a proper examination rather than a guess.
