It causes sudden attacks of vertigo lasting two to three hours, with ringing in the ears (tinnitus) and progressive hearing loss. Meniere’s disease is a rare condition that affects the inner ear. We all experience this to a certain extent when you are sitting on a train and it pulls out slowly from the station, it can be hard to know what’s moving. This group will think they are moving because the signal from their eyes isn’t being integrated with the information from their body. Some people are prone to vertigo because they are more visually dependent than others. Why do some people get vertigo more than others? Conversely, anxiety itself can cause unsteadiness people say it feels as if the world is moving under their feet. The extra adrenaline can cause unpleasant symptoms such as palpitations and anxiety. Illusions of movement activate the autonomic nervous system, which includes an adrenaline-fuelled fight-or-flight reaction. There is certainly a link to stress animals, including us, rely on signals about movement of predators and prey to survive.

Modifying the electrical activity in this may relieve vertigo. An electrical coil is placed over the head overlying the part of the brain – the parietal lobe – that processes balance. Kaski is interested in non-invasive brain stimulation. Prochlorperazine is good for nausea, but Betahistine, often prescribed by GPs, doesn’t help much at the doses that are given. Drug treatment of BPPV doesn’t work very well, according to Kaski. You will be guided through the exercises without having to wait months for an appointment with a trained physiotherapist. Kaski is exploring novel ways of delivering this treatment using virtual reality glasses and a mobile phone app. BPPV can be cured by head movement exercises (for example, the Epley manoeuvre or Brandt-Daroff exercises) that reset the inner-ear organ of balance. This kick-starts the brain into compensating for the vertigo so it doesn’t become a long-term problem. Medical advice for vestibular neuritis is to avoid bed rest and get back to normal life as quickly as possible. The treatment is the same as managing migraine headaches: try to identify and avoid triggers, short-term painkillers and anti-sickness medication and long-term preventive treatments such as beta blockers. These people may be hypersensitive to light, noise and smells. One in 10 people with migraines get bouts of vertigo which come and go, that don’t necessarily coincide with the more typical symptoms of a headache and can last from a few seconds to a few days. The repeated attacks usually last less than 30 seconds, and are precipitated by head movements including rolling over in bed or looking up. In vertigo, the inner-ear signals cause jerky, uncoordinated eye movements, known as nystagmus, which conflict with the brain’s other movement signals.

We have crystals inside the inner-ear balance organs that move when we do, but if the signals lag behind those emitted from the eyes and limbs, it creates an illusion of movement. But Kaski says vertigo is often mislabelled as this when in fact benign paroxysmal positional vertigo (BBPV), and vestibular migraine are the more common and likely culprits.īPPV is a mechanical problem of the inner ear. Vertigo is often attributed to an inner ear infection called vestibular neuritis that starts after a cold and can last for up to a couple of weeks. But in true vertigo, you feel as though you are standing still while the world moves around you. Normally, the brain recognises that you are moving by integrating signals from your eyes, inner ear and receptors that sense body movement in the neck and limbs. When you move your head, it can feel like what you are looking at has to ‘catch up’ with you afterwards.”ĭr Diego Kaski, neuro-otologist at London’s Charing Cross hospital, says vertigo creates the illusion of movement. It can be a lightheaded feeling, like you are going to faint, which is more likely to be a cardiovascular or breathing pattern problem. Specialist physiotherapist Nicola Harris says “dizziness covers a multitude of things.
