What is vertigo?
Vertigo is a symptom in which you feel as if you are moving, spinning or floating, even if you are stationary. Vertigo is often accompanied by other symptoms, such as dizziness, impaired balance, lightheadedness, and nausea. It is estimated that four out of ten Americans may have an episode of vertigo and seek medical attention (Source: NIH).
There are two main types of vertigo, peripheral and central. Peripheral vertigo affects the vestibular system, which includes the inner ear and vestibular nerve and controls balance. Central vertigo is the result of a problem related to the brain.
There are many causes of both types of vertigo, including medication side effects, infection, disorders, and injuries. In some cases, there is no known cause of vertigo. Vertigo may begin or end suddenly, or gradually worsen over time. Vertigo may be temporary or long-term, depending on the underlying cause.
Vertigo may be a symptom of serious or life-threatening condition, such as a traumatic brain injury. Seek immediate medical care (call 911) if you have vertigo and other serious symptoms, such as changes in consciousness, vomiting, severe headache, and abnormal behavior.
Seek prompt medical care if your vertigo is persistent or causes you concern.
What other symptoms might occur with vertigo?
Vertigo may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. Symptoms that frequently affect the vestibular system may also involve other body systems.

What causes vertigo?
There are two main types of vertigo, peripheral vertigo and central vertigo. Peripheral vertigo occurs as the result of a problem with the vestibular system, which includes the inner ear and vestibular nerve and controls balance. Central vertigo is the result of a problem related to the brain. In many cases, the precise cause of vertigo is not identified.
Causes of peripheral vertigo
Conditions, damage and diseases affecting to the inner ear and vestibular nerve causing peripheral vertigo include:
Acoustic neuroma (benign tumor of the acoustic nerve)
Benign positional vertigo (vertigo that occurs only in certain head positions)
Labyrinthitis (infection or inflammation of the inner ear)
Meniere’s disease (disorder of the inner ear characterized by vertigo and ringing in the ears)
Perilymphatic fistula (leakage of fluid from the inner ear to the middle ear)
Medication side effects
Vestibular neuronitis (inflammation of the vestibular nerve)
Causes of central vertigo
Vertigo can also be caused by conditions, damage and diseases affecting the brain including:
Exposure to toxic substances or poisons
Side effects of medications or drugs, including alcohol, anticonvulsants and aspirin
Serious or life-threatening causes of vertigo
