Patient information: Dizziness and vertigo (Beyond the Basics)

INTRODUCTION

Dizziness is a feeling that may be hard to describe, but often includes a feeling that you are spinning or tilting, or that you are about to fall or pass out. Dizziness can also cause you to feel lightheaded or giddy, or have difficulty walking straight.

Many people who feel dizzy have vertigo, a specific type of dizziness. Vertigo causes a sense of spinning dizziness, swaying, or tilting. You may feel that you are moving or that the room is moving around you. Vertigo can be caused by a number of different problems involving the inner ear or brain. Some of these problems are not serious while others can be life threatening.

This article will describe the symptoms of vertigo and help you to know when to seek help. More detailed information about vertigo is available by subscription. (See "Evaluation of the patient with vertigo" and "Treatment of vertigo".)

VERTIGO SYMPTOMS

The most common symptoms of vertigo include a feeling of:

Spinning (you or the room around you)

Tilting or swaying

Feeling off balance

These feelings come and go, and may last seconds, hours, or days. You may feel worse when you move your head, change positions (stand up, roll over), cough, or sneeze. Along with vertigo, you may:

Vomit or feel nauseous

Have a headache or be sensitive to light and noise

See double, have trouble speaking or swallowing, or feel weak

Feel short of breath or sweaty, have a racing heart beat

If you seek treatment for vertigo, you should mention how long these symptoms last, what triggers the symptoms, and any other associated problems. These clues can help point to the cause of vertigo.

COMMON CAUSES OF VERTIGO

The most common causes of vertigo include:

Inner ear problems — Collections of calcium, inflammation, and certain infections can cause problems in the vestibular system. The vestibular system includes parts of the inner ear and nervous system, which controls balance (figure 1). Benign paroxysmal positional vertigo, Meniere disease, and vestibular neuritis are three of the most common types of vertigo caused by inner ear problems.

Benign paroxysmal positional vertigo (BPPV) — BPPV, sometimes called benign positional vertigo, positional vertigo, postural vertigo, or simply vertigo, is a type of vertigo that develops due to collections of calcium in the inner ear. These collections are called canaliths. Moving the canaliths (called canalith repositioning) is a common treatment for BPPV. Vertigo is typically brief in people with BPPV, lasting seconds to minutes. Vertigo can be triggered by moving the head in certain ways. (See "Benign paroxysmal positional vertigo".)

Meniere disease — Meniere disease is a condition that causes repeated spells of vertigo, hearing loss, and ringing in the ears. Spells can last several minutes or hours. It is probably caused by a buildup of fluid in the inner ear. (See "Meniere disease".)

Vestibular neuritis — Vestibular neuritis, also known as labyrinthitis, is probably caused by a virus that causes swelling around the balance nerve. People with vestibular neuritis develop sudden, severe vertigo, nausea, vomiting, and difficulty walking or standing up; these problems can last several days. Some people also develop difficulty hearing in one ear. (See "Vestibular neuritis and labyrinthitis".)

Head injury — Head injuries can affect the vestibular system in a variety of ways, and lead to vertigo. (See "Concussion and mild traumatic brain injury", section on 'Post-traumatic vertigo'.)

Medications — Rarely, medications can actually damage the inner ear. Other medications can affect the function of the inner ear or brain and lead to vertigo.

Migraines — In a condition called vestibular migraine or migrainous vertigo, vertigo can be caused by a migraine. This type of vertigo usually happens along with a headache, although sometimes there is no headache. (See "Vestibular migraine".)

Brain problems, such as a stroke or TIA (transient ischemic attack), bleeding in the brain, or multiple sclerosis can also cause vertigo. There are usually other symptoms, besides vertigo, that happen with these brain problems. (See "Pathophysiology, etiology, and differential diagnosis of vertigo".)

WHEN TO SEEK HELP

You should seek help immediately if you have dizziness or vertigo along with any of the following:

New or severe headache

Temperature greater than 100.4ºF (38ºC)

Seeing double or having trouble seeing clearly

Trouble speaking or hearing

Weakness in an arm or leg

An inability to walk without assistance

Passing out

Numbness or tingling

Chest pain

Vomiting that will not stop

In addition, you should seek help immediately if you have vertigo that lasts for several minutes or more if you:

Are an older adult

Have had a stroke in the past

Have risk factors for stroke (high blood pressure, diabetes, smoking)

If you have dizziness or vertigo that comes and goes but you do not have any of the above problems, make an appointment with your doctor or nurse. He or she will perform a physical exam, and may order further testing, depending on your exam and medical history.

VERTIGO TREATMENT

In most people, vertigo is bothersome but it is not caused by a serious problem. Treatment for vertigo aims to treat the underlying cause (if the cause is known), relieve the bothersome symptoms, and help with recovery. This section will discuss treatment for symptoms and treatments to help with recovery.

Treatment for symptoms — If you have spells of vertigo that are severe or last for hours or days, your doctor or nurse may recommend a medication to relieve severe vertigo symptoms, like vomiting. Treatment with medication is not usually recommended if your vertigo lasts only second or minutes.

Possible medication treatments include:

An antihistamine, such as the prescription medicine meclizine (Antivert®), or non-prescription medicines like dimenhydrinate (Dramamine®), or diphenhydramine (Benadryl®).

Prescription anti-nausea medicines, such as promethazine (Phenergan®), metoclopramide (Reglan®), or ondansetron (Zofran®).

Prescription sedative medicines, such as diazepam (Valium®), lorazepam (Ativan®), or clonazepam (Klonopin®)

Most of these medicines make you sleepy, and you should not take them before you work or drive. You should only take prescription medicines to treat severe vertigo symptoms, and you should stop the medicine when your symptoms improve.

Canalith repositioning — Canalith repositioning is a treatment that may be recommended for people with benign paroxysmal positional vertigo (BPPV). The treatment will be done by a doctor, nurse, or therapist in the office by moving your head into certain positions, sometimes called the Epley maneuver. You may be given instructions on how to perform similar movements at home, if needed.

These movements encourage the calcium collection to move into a part of the ear where it will be reabsorbed. You may begin to feel better immediately after this treatment or within a day or two.

Balance rehabilitation — Most patients with vertigo prefer to keep their head still. However, staying still and not moving your head can make it harder to cope with vertigo. Rehabilitation can help people with vertigo that is caused by injury to the vestibular system. The vestibular system includes parts of the inner ear and nervous system, which controls balance.

The rehabilitation works by helping your brain adjust its response to changes in the vestibular system. The therapy can also help train your eyes and other senses to "learn" how to compensate. This therapy is most helpful when it is started as soon as possible after you develop vertigo.

During rehabilitation, you will work with a therapist who will teach to you perform exercises at home. For example, you might start by focusing on an object with a blank background and move your head slowly to the right and left and up and down. You would perform this exercise for several minutes two to three times per day.

If you have trouble standing or walking because of vertigo, you are at risk for falling. In older adults, falls can lead to serious complications, such as a broken hip. Talk to your doctor, nurse, or therapist about your concerns. To reduce the risk of falls, get rid of hazards in your home, such as loose electrical cords and slippery rugs, and avoid walking in unfamiliar areas that are not lighted.
