According to a medical blog on Vertigo posted by WebMD.com, vertigo is the feeling that you or your environment is moving or spinning. It differs from dizziness in that vertigo describes an illusion of movement. When you feel as if you yourself are moving, it’s called subjective vertigo, and the perception that your surroundings are moving is called objective vertigo.
Unlike nonspecific lightheadedness or dizziness, vertigo has relatively few causes, such as Head trauma and neck injury.
Vertigo Symptoms Vertigo implies that there is a sensation of motion either of the person or the environment, often perceived as if the room is spinning around you. This should not be confused with symptoms of lightheadedness or fainting. Vertigo differs from motion sickness in that motion sickness is a feeling of being off-balance and lacking equilibrium, caused by repeated motions such as riding in a car or boat.
- If true vertigo exists, symptoms include a sensation of disorientation or motion. In addition, the individual may also have any or all of these symptoms:
- nausea or vomiting,
- sweating, and/or abnormal eye movements.
- The duration of symptoms can be from minutes to hours, and symptoms can be constant or episodic. The onset may be due to a movement or change in position. It is important to tell the doctor about any recent head trauma orwhiplash injury as well as any new medications the affected individual is taking.
- The person may have hearing loss and a ringing sensation in the ears.
- The person might have visual disturbances, weakness, difficulty speaking, a decreased level of consciousness, and difficulty walking.
When to Seek Medical Care Any signs and symptoms of vertigo warrant an evaluation by a doctor. The majority of cases of vertigo are harmless. Although vertigo can be debilitating, most causes are easily treated with prescription medication. Have a doctor check any new signs and symptoms of vertigo to rule out rare, potentially serious or life-threatening causes.
Certain signs and symptoms of vertigo may require evaluation in a hospital’s emergency department:
- Double vision
- Difficulty speaking
- Abnormal eye movements
- Altered level of consciousness, not acting appropriately, or difficulty arousing
- Difficulty walking or controlling the arms and legs
Exams and Tests The evaluation of vertigo consists primarily of amedical history and physical exam.
The history is comprised of four basic areas.
- The doctor may want to know if the patient feels any sensation of motion, which may indicate that true vertigo exists. Report any nausea, vomiting, sweating, and abnormal eye movements.
- The doctor may ask how long the patient has symptoms and whether they are constant or come and go. Do the symptoms occur when moving or changing positions? Is the patient currently taking any new medications? Has there been any recent head trauma or whiplash injury?
- Are there any other hearing symptoms? Specifically, report any ringing in the ears or hearing loss.
- Does the patient have other neurological symptoms such as weakness, visual disturbances, altered level of consciousness, difficulty walking, abnormal eye movements, or difficulty speaking?
The doctor may perform tests such as a CT scan if a brain injury is suspected to be the cause of vertigo.
Blood tests to check blood sugar levels and the use of an electrocardiogram (ECG) to look at heart rhythm may also be helpful.
Vertigo Medical Treatment The choice of treatment will depend on the diagnosis.
- Vertigo can be treated with medicine taken by mouth, through medicine placed on the skin (a patch), or drugs given through an IV.
- Specific types of vertigo may require additional treatment and referral:
- Bacterial infection of the middle ear requires antibiotics.
- For Meniere’s disease, in addition to symptomatic treatment, people might be placed on a low salt diet and may require medication used to increase urine output.
- A hole in the inner ear causing recurrent infection may require referral to an ear, nose, and throat (ENT) specialist for surgery.
- In addition to the drugs used for benign paroxysmal positional vertigo, several physical maneuvers can be used to treat the condition.
- Vestibular rehabilitation exercises, also referred to as Epley maneuvers, consist of having the patient sit on the edge of a table and lie down to one side until the vertigo resolves followed by sitting up and lying down on the other side, again until the vertigo ceases. This is repeated until the vertigo no longer occurs.
- Particle repositioning maneuver is a treatment based on the idea that the condition is caused by displacement of tiny stones in the balance center (vestibular system) of the inner ear. The head is repositioned to move the stones to their normal position. This maneuver is repeated until the abnormal eye movements are no longer visible.
Commonly prescribed medications for vertigo include the following:
- meclizine hydrochloride (Antivert)
- diphenhydramine (Benadryl)
- scopolamine transdermal patch (Transderm-Scop)
- promethazine hydrochloride (Phenergan)
- diazepam (Valium)
Follow-up Anyone with a new diagnosis of vertigo should follow-up with his or her doctor or be referred directly to a neurologist or ENT specialist.
